I personally don’t think that electric cars will ever be viable because battery development is too slow, and given that oil can be hundreds of times more energy dense than a battery of the same weight, the laws of physics will prevent them from ever achieving enough energy density — see my post at Who Killed the Electric Car. (and also my more-up-to-date version and utility-scale energy storage batteries in my book When Trains Stop Running: Energy and the Future of Transportation.  Some excerpts from my book about lithium and energy storage:

Li-ion energy storage batteries are more expensive than PbA or NaS, can be charged and discharged only a discrete number of times, can fail or lose capacity if overheated, and the cost of preventing overheating is expensive. Lithium does not grow on trees. The amount of lithium needed for utility-scale storage is likely to deplete known resources (Vazquez, S., et al. 2010. Energy storage systems for transport and grid applications. IEEE Transactions on Industrial Electronics 57(12): 3884).

To provide enough energy for 1 day of storage for the United states, li-ion batteries would cost $11.9 trillion dollars, take up 345 square miles and weigh 74 million tons (DOE/EPRI. 2013. Electricity storage handbook in collaboration with NRECA. USA: Sandia National Laboratories and Electric Power Research Institute) 

Barnhart et al. (2013) looked at how much materials and energy it would take to make batteries that could store up to 12 hours of average daily world power demand, 25.3 TWh. Eighteen months of world-wide primary energy production would be needed to mine and manufacture these batteries, and material production limits were reached for many minerals even when energy storage devices got all of the world’s production (with zinc, sodium, and sulfur being the exceptions). Annual production by mass would have to double for lead, triple for lithium, and go up by a factor of 10 or more for cobalt and vanadium, driving up prices. The best to worst in terms of material availability are: CAES, NaS, ZnBr, PbA, PHS, Li-ion, and VRB (Barnhart, C., et al. 2013. On the importance of reducing the energetic and material demands of electrical energy storage. Energy Environment Science 2013(6): 1083–1092). ]

Abstract

Lithium is a highly interesting metal, in part due to the increasing interest in lithium-ion batteries. Several recent studies have used different methods to estimate whether the lithium production can meet an increasing demand, especially from the transport sector, where lithium-ion batteries are the most likely technology for electric cars. The reserve and resource estimates of lithium vary greatly between different studies and the question whether the annual production rates of lithium can meet a growing demand is seldom adequately explained. This study presents a review and compilation of recent estimates of quantities of lithium available for exploitation and discusses the uncertainty and differences between these estimates. Also, mathematical curve fitting models are used to estimate possible future annual production rates. This estimation of possible production rates are compared to a potential increased demand of lithium if the International Energy Agency’s Blue Map Scenarios are fulfilled regarding electrification of the car fleet. We find that the availability of lithium could in fact be a problem for fulfilling this scenario if lithium-ion batteries are to be used. This indicates that other battery technologies might have to be implemented for enabling an electrification of road transports.

  • Review of reserves, resources and key properties of 112 lithium deposits
  • Discussions of widely diverging results from recent lithium supply estimates
  • Forecasting future lithium production by resource-constrained models
  • Exploring implications for future deployment of electric cars

Introduction

Global transportation mainly relies on one single fossil resource, namely petroleum, which supplies 95% of the total energy [1]. In fact, about 62% of all world oil consumption takes place in the transport sector [2]. Oil prices have oscillated dramatically over the last few years, and the price of oil reached $100 per barrel in January 2008, before skyrocketing to nearly $150/barrel in July 2008. A dramatic price collapse followed in late 2008, but oil prices have at present time returned to over $100/barrel. Also, peak oil concerns, resulting in imminent oil production limitations, have been voiced by various studies [3–6].

It has been found that continued oil dependence is environmentally, economically and socially unsustainable [7].

The price uncertainty and decreasing supply might result in severe challenges for different transporters. Nygren et al. [8] showed that even the most optimistic oil production forecasts implied pessimistic futures for the aviation industry. Curtis [9] found that globalization may be undermined by peak oil’s effect on transportation costs and reliability of freight.

Barely 2% of the world electricity is used by transportation [2], where most of this is made up by trains, trams, and trolley buses.

A high future demand of Li for battery applications may arise if society choses to employ Li-ion technologies for a decarbonization of the road transport sector.

Batteries are at present time the second most common use, but are increasing rapidly as the use of li-ion batteries for portable electronics [12], as well as electric and hybrid cars, are becoming more frequent. For example, the lithium consumption for batteries in the U.S increased with 194 % from 2005 to 2010 [12]. Relatively few academic studies have focused on the very abundance of raw materials needed to supply a potential increase in Li demand from transport sector [13]. Lithium demand is growing and it is important to investigate whether this could lead to a shortfall in the future.

 

[My comment: utility scale energy storage batteries in commercial production are lithium, and if this continues, this sector alone would quickly consume all available lithium supplies: see Barnhart, C., et al. 2013. On the importance of reducing the energetic and material demands of electrical energy storage. Energy Environment Science 2013(6): 1083–1092.]

Aim of this study

Recently, a number of studies have investigated future supply prospects for lithium [13–16]. However, these studies reach widely different results in terms of available quantities, possible production trajectories, as well as expected future demand. The most striking difference is perhaps the widely different estimates for available resources and reserves, where different numbers of deposits are included and different types of resources are assessed. It has been suggested that mineral resources will be a future constraint for society [17], but a great deal of this debate is often spent on the concept of geological availability, which can be presented as the size of the tank. What is frequently not reflected upon is that society can only use the quantities that can be extracted at a certain pace and be delivered to consumers by mining operations, which can be described as the tap. The key concept here is that the size of the tank and the size of the tap are two fundamentally different things.

This study attempts to present a comprehensive review of known lithium deposits and their estimated quantities of lithium available for exploitation and discuss the uncertainty and differences among published studies, in order to bring clarity to the subject. The estimated reserves are then used as a constraint in a model of possible future production of lithium and the results of the model are compared to possible future demand from an electrification of the car fleet. The forecasts are based on open, public data and should be used for estimating long term growth and trends. This is not a substitute for economical short-term prognoses, but rather a complementary vision.

Data sources

The United States Geological Survey (USGS) has been particularly useful for obtaining production data series, but also the Swedish Geological Survey (SGU) and the British Geological Survey (BGS) deserves honourable mention for providing useful material. Kushnir and Sandén [18], Tahil [19, 20] along with many other recent lithium works have also been useful. Kesler et al. [21] helped to provide a broad overview of general lithium geology.

Information on individual lithium deposits has been compiled from numerous sources, primarily building on the tables found in [13–16]. In addition, several specialized articles about individual deposits have been used, for instance [22–26]. Public industry reports and annual yearbooks from mining operators and lithium producers, such as SQM [27], Roskill [28] or Talison Lithium [29], also helped to create a holistic data base.

In this study, we collected information on global lithium deposits. Country of occurrence, deposit type, main mineral, and lithium content were gathered as well as published estimates for reserves and resources. Some deposits had detailed data available for all parameters, while others had very little information available. Widely diverging estimates for reserves and resources could sometimes be found for the same deposit, and in such cases the full interval between the minimum and maximum estimates is presented. Deposits without reserve or resource estimates are included in the data set, but do not contribute to the total. Only available data and information that could be found in the public and academic spheres were compiled in this study. It is likely that undisclosed and/or proprietary data could contribute to the world’s lithium volume but due to data availability no conclusions on to which extent could be made.

Geological overview

In order to properly estimate global lithium availability, and a feasible reserve estimate for modelling future production, this section presents an overview of lithium geology. Lithium is named after the Greek word “lithos” meaning “stone”, represented by the symbol Li and has the atomic number 3. Under standard conditions, lithium is the lightest metal and the least dense solid element. Lithium is a soft, silver-white metal that belongs to the alkali group of elements.

As all alkali elements, Li is highly reactive and flammable. For this reason, it never occurs freely in nature and only appears in compounds, usually ionic compounds. The nuclear properties of Li are peculiar since its nuclei verge on instability and two stable isotopes have among the lowest binding energies per nucleon of all stable nuclides. Due to this nuclear instability, lithium is less abundant in the solar system than 25 of the first 32 chemical elements [30].

Resources and reserves

An important frequent shortcoming in the discussion on availability of lithium is the lack of proper terminology and standardized concepts for assessing the available amounts of lithium. Published studies talk about “reserves”, “resources”, “recoverable resources”, “broad-based reserves”, “in-situ resources”, and “reserve base”.

A wide range of reporting systems minerals exist, such as NI 43-101, USGS, Crirsco, SAMREC and the JORC code, and further discussion and references concerning this can be found in Vikström [31]. Definitions and classifications used are often similar, but not always consistent, adding to the confusion when aggregating data. Consistent definitions may be used in individual studies, but frequently figures from different methodologies are combined as there is no universal and standardized framework. In essence, published literature is a jumble of inconsistent figures. If one does not know what the numbers really mean, they are not simply useless – they are worse, since they tend to mislead.

Broadly speaking, resources are generally defined as the geologically assured quantity that is available for exploitation, while reserves are the quantity that is exploitable with current technical and socioeconomic conditions. The reserves are what are important for production, while resources are largely an academic figure with little relevance for real supply. For example, usually less than one tenth of the coal resources are considered economically recoverable [32, 33]. Kesler et al. [21] stress that available resources needs to be converted into reserves before they can be produced and used by society. Still, some analysts seemingly use the terms ‘resources’ and ‘reserves’ synonymously.

It should be noted that the actual reserves are dynamic and vary depending on many factors such as the available technology, economic demand, political issues and social factors. Technological improvements may increase reserves by opening new deposit types for exploitation or by lowering production costs. Deposits that have been mined for some time can increase or decrease their reserves due to difficulties with determining the ore grade and tonnage in advance [34]. Depletion and decreasing concentrations may increase recovery costs, thus lowering reserves. Declining demand and prices may also reduce reserves, while rising prices or demand may increase them. Political decisions, legal issues or environmental policies may prohibit exploitation of certain deposits, despite the fact significant resources may be available.

For lithium, resource/reserve classifications were typically developed for solid ore deposits. However, brine – presently the main lithium source – is a fluid and commonly used definitions can be difficult to apply due to pumping complications and varying concentrations.

Houston et al. [35] describes the problem in detail and suggest a change in NI 43-101 to account for these problems. If better standards were available for brines then estimations could be more reliable and accurate, as discussed in Kushnir and Sandén [18].

Environmental aspects and policy changes can also significantly influence recoverability. Introduction of clean air requirements and public resistance to surface mining in the USA played a major role in the decreasing coal reserves [33].

It is entirely possible that public outcries against surface mining or concerns for the environment in lithium producing will lead to restrictions that affect the reserves. As an example, the water consumption of brine production is very high and Tahil [19] estimates that brine operations consume 65% of the fresh water in the Salar de Atacama region. [ The Atacama only gets 0.6 inches of rain a year ]

Regarding future developments of recoverability, Fasel and Tran [36] monotonously assumes that increasing lithium demand will result in more reserves being found as prices rise. So called cumulative availability curves are sometimes used to estimate how reserves will change with changing prices, displaying the estimated amount of resource against the average unit cost ranked from lowest to highest cost. This method is used by Yaksic and Tilton [14] to address lithium availability. This concept has its merits for describing theoretical availability, but the fact that the concept is based on average cost, not marginal cost, has been described as a major weakness, making cumulative availability curves disregard the real cost structure and has little – if any – relevance for future price and production rate [37].

Production and occurrence of lithium

The high reactivity of lithium makes it geochemistry complex and interesting. Lithium-minerals are generally formed in magmatic processes. The small ionic size makes it difficult for lithium to be included in early stages of mineral crystallization, and resultantly lithium remains in the molten parts where it gets enriched until it can be solidified in the final stages [38].

At present, over 120 lithium-containing minerals are known, but few of them contain high concentrations or are frequently occurring. Lithium can also be found in naturally occurring salt solutions as brines in dry salt lake environments. Compared to the fairly large number of lithium mineral and brine deposits, few of them are of actual or potential commercial value. Many are very small, while others are too low in grade [39]. This chapter will briefly review the properties of those deposits and present a compilation of the known deposits.

Lithium mineral deposits

Lithium extraction from minerals is primarily done with minerals occurring in pegmatite formations. However, pegmatite is rather challenging to exploit due to its hardness in conjunction with generally problematic access to the belt-like deposits they usually occur in. Table 1 describes some typical lithium-bearing minerals and their characteristics. Australia is currently the world’s largest producer of lithium from minerals, mainly from spodumene [39]. Petalite is commonly used for glass manufacture due to its high iron content, while lepidolite was earlier used as a lithium source but presently has lost its importance due to high fluorine content. Exploitation must generally be tailor-made for a certain mineral as they differ quite significantly in chemical composition, hardness and other properties[13]. Table 2 presents some mineral deposits and their properties.

Recovery rates for mining typically range from 60 to 70%, although significant treatment is required for transforming the produced Li into a marketable form. For example, [40, 41] describe how lithium are produced from spodumene. The costs of acid, soda ash, and energy are a very significant part of the total production cost but may be partially alleviated by the market demand for the sodium sulphate by-products.

Lithium brine deposits

Lithium can also be found in salt lake brines that have high concentrations of mineral salts. Such brines can be reachable directly from the surface or deep underground in saline expanses located in very dry regions that allow salts to persist. High concentration lithium brine is mainly found in high altitude locations such as the Andes and south-western China. Chile, the world largest lithium producer, derives most of the production from brines located at the large salt flat of Salar de Atacama.

Lithium has similar ionic properties as magnesium since their ionic size is nearly identical; making is difficult to separate lithium from magnesium. A low Mg/Li ratio in brine means that it is easier, and therefore more economical to extract lithium.

Lithium Market Research SISThe ratio differs significant at currently producing brine deposits and range from less than 1 to over 30 [14]. The lithium concentration in known brine deposits is usually quite low and range from 0.017–0.15% with significant variability among the known deposits in the world (Table 3).

Exploitation of lithium brines starts with the brine being pumped from the ground into evaporation ponds. The actual evaporation is enabled by incoming solar radiation, so it is desirable for the operation to be located in sunny areas with low annual precipitation rate. The net evaporation rate determines the area of the required ponds [42].

It can easily take between one and two years before the final product is ready to be used, and even longer in cold and rainy areas.

The long timescales required for production can make brine deposits ill fit for sudden changes in demand. Table 3. Properties of known brine deposits in the world.

Lithium from sea water

The world’s oceans contain a wide number of metals, such as gold, lithium or uranium, dispersed at low concentrations. The mass of the world’s oceans is approximately 1.35*1012 Mt [47], making vast amounts of theoretical resources seemingly available. Eckhardt [48] and Fasel and Tran [36] announce that more than 2,000,000 Mt lithium is available from the seas, essentially making it an “unlimited” source given its geological abundance. Tahil [20] also notes that oceans have been proclaimed as an unlimited Li-source since the 1970s.

The world’s oceans and some highly saline lakes do in fact contain very large quantities of lithium, but if it will become practical and economical to produce lithium from this source is highly questionable.

For example, consider gold in sea water – in total nearly 7,000,000 Mt. This is an enormous amount compared to the cumulative world production of 0.17 Mt accumulated since the dawn of civilization [49]. There are also several technical options available for gold extraction. However, the average gold concentration range from <0.001 to 0.005 ppb [50]. This means that one km3 of sea water would give only 5.5 kg of gold. The gold is simply too dilute to be viable for commercial extraction and it is not surprising that all attempts to achieve success – including those of the Nobel laureate Fritz Haber – has failed to date.

Average lithium concentration in the oceans has been estimated to 0.17 ppm [14, 36]. Kushnir and Sandén [18] argue that it is theoretically possible to use a wide range of advanced technologies to extract lithium from seawater – just like the case for gold. However, no convincing methods have been demonstrated this far. A small scale Japanese experiment managed to produce 750 g of lithium metal from processing 4,200 m3 water with a recovery efficiency of 19.7% [36]. This approach has been described in more detail by others [51–53].

Grosjean et al. [13] points to the fact that even after decades of improvement, recovery from seawater is still more than 10–30 times more costly than production from pegmatites and brines. It is evident that huge quantities of water would have to be processed to produce any significant amounts of lithium. Bardi [54] presents theoretical calculations on this, stating that a production volume of lithium comparable to present world production (~25 kt annually) would require 1.5*103 TWh of electrical energy for pumping through separation membranes in addition to colossal volumes of seawater. Furthermore, Tahil [20] estimated that a seawater processing flow equivalent to the average discharge of the River Nile – 300,000,000 m3/day or over 22 times the global petroleum industry flow of 85 million barrels per day – would only give 62 tons of lithium per day or roughly 20 kt per year. Furthermore, a significant amount of fresh water and hydrochloric acid will be required to flush out unwanted minerals (Mg, K, etc.) and extract lithium from the adsorption columns [20].

In summary, extraction from seawater appears not feasible and not something that should be considered viable in practice, at least not in the near future.

Estimated lithium availability

From data compilation and analysis of 112 deposits, this study concludes that 15 Mt areImage result for lithium reasonable as a reference case for the global reserves in the near and medium term. 30 Mt is seen as a high case estimate for available lithium reserves and this number is also found in the upper range in literature. These two estimates are used as constraints in the models of future production in this study.

Estimates on world reserves and resources vary significantly among published studies. One main reason for this is likely the fact that different deposits, as well as different number of deposits, are aggregated in different studies. Many studies, such as the ones presented by the USGS, do not give explicitly state the number of deposits included and just presents aggregated figures on a national level. Even when the number and which deposits that have been used are specified, analysts can arrive to wide different estimates (Table 5). It should be noted that a trend towards increasing reserves and resources with time can generally be found, in particularly in USGS assessments. Early reports, such as Evans [56] or USGS [59], excluded several countries from the reserve estimates due to a lack of available information. This was mitigated in USGS [73] when reserves estimates for Argentina, Australia, and Chile have been revised based on new information from governmental and industry sources. However, there are still relatively few assessments on reserves, in particular for Russia, and it is concluded that much future work is required to handle this shortcoming. Gruber et al. [16] noted that 83% of global lithium resources can be found in six brine, two pegmatite and two sedimentary deposits. From our compilation, it can also be found that the distribution of global lithium reserves and resources are very uneven.

Three quarters of everything can typically be found in the ten largest deposits (Figure 1 and 2). USGS [12] pinpoint that 85% of the global reserves are situated in Chile and China (Figure 3) and that Chile and Australia accounted for 70 % of the world production of 28,100 tonnes in 2011 [12]. From Table 2 and 3, one can note a significant spread in estimated reserves and resources for the deposits. This divergence is much smaller for minerals (5.6–8.2 Mt) than for brines (6.5– 29.4 Mt), probably resulting from the difficulty associated with estimating brine accumulations consistently. Evans [75] also points to the problem of using these frameworks on brine deposits, which are fundamentally different from solid ores. Table 5. Comparison of published lithium assessments.

Recycling

One thing that may or may not have a large implication for future production is recycling. The projections presented in the production model of this study describe production of lithium from virgin materials. The total production of lithium could potentially increase significantly if high rates of recycling were implemented of the used lithium, which is mentioned in many studies.

USGS [12] state that recycling of lithium has been insignificant historically, but that it is increasing as the use of lithium for batteries are growing. However, the recycling of lithium from batteries is still more or less non-existent, with a collection rate of used Li-ion batteries of only about 3% [93]. When the Li-ion batteries are in fact recycled, it is usually not the lithium that is recycled, but other more precious metals such as cobalt [18].

If this will change in the future is uncertain and highly dependent on future metal prices, but it is still commonly argued for and assumed that the recycling of lithium will grow significantly, very soon. Goonan [94] claims that recycling rates will increase from vehicle batteries in vehicles since such recycling systems already exist for lead-acid batteries. Kushnir and Sandén [18] argue that large automotive batteries will be technically easier to recycle than smaller batteries and also claims that economies of scale will emerge when the use for batteries for vehicles increase. According to the IEA [95], full recycling systems are projected to be in place sometime between 2020 and 2030. Similar assumptions are made by more or less all studies dealing with future lithium production and use for electric vehicles and Kushnir and Sandén [18] state that it is commonly assumed that recycling will take place, enabling recycled lithium to make up for a big part of the demand but also conclude that the future recycling rate is highly uncertain.

There are several reasons to question the probability of high recycling shares for Li-ion batteries. Kushnir and Sandén [18] state that lithium recycling economy is currently not good and claims that the economic conditions could decrease even more in the future. Sullivan and Gaines [96] argue that the Li-ion battery chemistry is complex and still evolving, thus making it difficult for the industry to develop profitable pathways. Georgi-Maschler [93] highlight that two established recycling processes exist for recycling Li-ion batteries, but one of them lose most of the lithium in the process of recovering the other valuable metals. Ziemann et al. [97] states that lithium recovery from rechargeable batteries is not efficient at present time, mainly due to the low lithium content of around 2% and the rather low price of lithium.

In this study we choose not to include recycling in the projected future supply for several reasons. In a short perspective, looking towards 2015-2020, it cannot be considered likely that any considerable amount of lithium will be recycled from batteries since it is currently not economical to do so and no proven methods to do it on a large scale industrial level appear to exist. If it becomes economical to recycle lithium from batteries it will take time to build the capacity for the recycling to take place. Also, the battery lifetime is often projected to be 10 years or more, and to expect any significant amounts of lithium to be recycled within this period of time is simply not realistic for that reason either.

The recycling capacity is expected to be far from reaching significant levels before 2025 according to Wanger [92]. It is also important to separate the recycling rates of products to the recycled content in new products. Even if a percentage of the product is recycled at the end of the life cycle, this is no guarantee that the use of recycled content in new products will be as high. The use of Li-ion batteries is projected to grow fast. If the growth happens linearly, and high recycling rates are accomplished, recycling could start constituting a large part of the lithium demand, but if the growth happens exponentially, recycling can never keep up with the growth that has occurred during the 10 years lag during the battery lifetime. In a longer time perspective, the inclusion of recycling could be argued for with expected technological refinement, but certainties regarding technology development are highly uncertain. Still, most studies include recycling as a major part of future lithium production, which can have very large implications on the results and conclusions drawn. Kushnir and Sandén [18] suggest that an 80% lithium recovery rate is achievable over a medium time frame. The scenarios in Gruber et al. [16], assumes recycling participation rates of 90 %, 96% and 100%. In their scenario using the highest assumed recycling, the quantities of lithium needed to be mined are decreased to only about 37% of the demand. Wanger [92] looks at a shorter time perspective and estimates that a 40% or 100% recycling rate would reduce the lithium consumption with 10% or 25% respectively by 2030. Mohr et al. [15] assume that the recycling rate starts at 0%, approaching a limit of 80%, resulting in recycled lithium making up significant parts of production, but only several decades into the future. IEA [95] projects that full recycling systems will be in place around 2020–2030.

The impact of assumed recycling rates can indeed be very significant, and the use of this should be handled with care and be well motivated.

Future demand for lithium

To estimate whether the projected future production levels will be sufficient, it isImage result for lithiuminteresting to compare possible production levels with potential future demand. The use of lithium is currently dominated by use for ceramics and glass closely followed by batteries. The current lithium demand for different markets can be seen in Figure 7. USGS [12] state that the lithium use in batteries have grown significantly in recent years as the use of lithium batteries in portable electronics have become increasingly common. Figure 7 (Ceramics and glass 29%, Batteries 27%, Other uses 16%, Lubrication greases 12%, Continuous casting 5%, Air treatment 4%, Polymers 3%, Primary aluminum production 2%, Pharmaceuticals 2%).

Global lithium demand for different end-use markets. Source: USGS [12] USGS [12] state that the total lithium consumption in 2011 was between 22,500 and 24,500 tonnes. This is often projected to grow, especially as the use of Li-ion batteries for electric cars could potentially increase demand significantly. This study presents a simple example of possible future demand of lithium, assuming a constant demand for other uses and demand for electric cars to grow according to a scenario of future sales of

electric cars. The current car fleet consists of about 600 million passenger cars. The sale of new passenger cars in 2011 was about 60 million cars [98]. This existing vehicle park is almost entirely dependent on fossil fuels, primarily gasoline and diesel, but also natural gas to a smaller extent. Increasing oil prices, concerns about a possible peak in oil production and problems with anthropogenic global warming makes it desirable to move away from fossil energy dependence. As a mitigation and pathway to a fossil-fuel free mobility, cars running partially or totally on electrical energy are commonly proposed. This includes electric vehicles (EVs), hybrid vehicles (HEVs) and PHEVs (plug-in hybrid vehicles), all on the verge of large-scale commercialization and implementation. IEA [99] concluded that a total of 1.5 million hybrid and electric vehicles had been sold worldwide between the year 2000 and 2010.

Both the expected number of cars as well as the amount of lithium required per vehicle is important. As can be seen from Table 9, the estimates of lithium demand for PEHV and EVs differ significantly between studies. Also, some studies do not differentiate between different technical options and only gives a single Li-consumption estimate for an “electric vehicle”, for instance the 3 kg/car found by Mohr et al. [15]. The mean values from Table 9 are found to be 4.9 kg for an EV and 1.9 kg for a PHEV.

As the battery size determines the vehicles range, it is likely that the range will continue to increase in the future, which could increase the lithium demand. On the other hand, it is also reasonable to assume that the technology will improve, thus reducing the lithium requirements. In this study a lithium demand of 160 g Li/kWh is assumed, an assumption discussed in detail by Kushnir and Sandén [18]. It is then assumed that typical batteries capacities will be 9 kWh in a PHEV and 25 kWh in an EV. This gives a resulting lithium requirement of 1.4 kg for a PHEV and 4 kg for an EV, which is used as an estimate in this study. Many current electrified cars have a lower capacity than 24 kWh, but to become more attractive to consumers the range of the vehicles will likely have to increase, creating a need for larger batteries [104]. It should be added that the values used are at the lower end compared to other assessments (Table 9) and should most likely not be seen as overestimates future lithium requirements.

Figure 8 shows the span of the different production forecasts up until 2050 made in this study, together with an estimated demand based on the demand staying constant on the high estimate of 2010– 2011, adding an estimated demand created by the electric car projections done by IEA [101]. This is a very simplistic estimation future demand, but compared to the production projections it indicates that lithium availability should not be automatically disregarded as a potential issue for future electric car production. The amount of electric cars could very well be smaller or larger that this scenario, but the scenario used does not assume a complete electrification of the car fleet by 2050 and such scenarios would mean even larger demand of lithium. It is likely that lithium demand for other uses will also grow in the coming decades, why total demand might increase more that indicated here. This study does not attempt to estimate the evolution of demand for other uses, and the demand estimate for other uses can be considered a conservative one. Figure 8. The total lithium demand of a constant current lithium demand combined with growth of electric vehicles according to IEA’s blue map scenario [101] assuming a demand for 1.4 kg of lithium per PHEV and 4.0 kg per EV. The span of forecasted production levels range from the base case Gompertz model

Concluding discussion

Potential future production of lithium was modeled with three different production curves. In a short perspective, until 2015–2020, the three models do not differ much, but in the longer perspective the Richards and Logistic curves show a growth at a vastly higher pace than the Gompertz curve. The Richards model gives the best fit to the historic data, and lies in between the other two and might be the most likely development. A faster growth than the logistic model cannot be ruled out, but should be considered unlikely, since it usually mimics plausible free market exploitation [89]. Other factors, such as decreased lithium concentration in mined material, economics, political and environmental problems could also limit production.

It can be debated whether this kind of forecasting should be used for short term projections, and the actual production in coming years can very well differ from our models, but it does at least indicate that lithium availability could be a potential problem in the coming decades. In a longer time perspective up to 2050, the projected lithium demand for alternative vehicles far exceeds our most optimistic production prognoses.

If 100 million alternative vehicles, as projected in IEA [101] are produced annually using lithium battery technology, the lithium reserves would be exhausted in just a few years, even if the production could be cranked up faster than the models in this study. This indicates that it is important that other battery technologies should be investigated as well.

It should be added that these projections do not consider potential recycling of the lithium, which is discussed further earlier in this paper. On the other hand, it appears it is highly unlikely that recycling will become common as soon as 2020, while total demand appears to potentially rise over maximum production around that date. If, when, and to what extent recycling will take place is hard to predict, although it appears more likely that high recycling rates will take place in electric cars than other uses.

Much could change before 2050. The spread between the different production curves are much larger and it is hard to estimate what happens with technology over such a long time frame. However, the Blue Map Scenario would in fact create a demand of lithium that is higher than the peak production of the logistic curve for the standard case, and close to the peak production in the high URR case.

Improved efficiency can decrease the lithium demand in the batteries, but as Kushnir and Sandén [18] point out, there is a minimum amount of lithium required tied to the cell voltage and chemistry of the battery.

IEA [95] acknowledges that technologies that are not available today must be developed to reach the Blue Map scenarios and that technology development is uncertain. This does not quite coincide with other studies claiming that lithium availability will not be a problem for production of electric cars in the future.

It is also possible that other uses will raise the demand for lithium even further. One industry that in a longer time perspective could potentially increase the demand for lithium is fusion, where lithium is used to breed tritium in the reactors. If fusion were commercialized, which currently seems highly uncertain, it would demand large volumes of lithium [36].

Further problems with the lithium industry are that the production and reserves are situated in a few countries (USGS [12] in Mt: Chile 7.5, China 3.5, Australia 0.97, Argentina 0.85, Other 0.135]. One can also note that most of the lithium is concentrated to a fairly small amount of deposits, nearly 50% of both reserves and resources can be found in Salar de Atacama alone. Kesler et al. [21] note that Argentina, Bolivia, Chile and China hold 70% of the brine deposits. Grosjean et al. [13] even points to the ABC triangle (i.e. Argentina, Bolivia and Chile) and its control of well over 40% of the world resources and raises concern for resource nationalism and monopolistic behavior. Even though Bolivia has large resources, there are many political and technical problems, such as transportation and limited amount of available fresh water, in need of solutions [18].

Regardless of global resource size, the high concentration of reserves and production to very few countries is not something that bode well for future supplies. The world is currently largely dependent on OPEC for oil, and that creates possibilities of political conflicts. The lithium reserves are situated in mainly two countries. It could be considered problematic for countries like the US to be dependent on Bolivia, Chile and Argentina for political reasons [105]. Abell and Oppenheimer [105] discuss the absurdity in switching from dependence to dependence since resources are finite. Also, Kushnir and Sandén [18] discusses the problems with being dependent on a few producers, if a problem unexpectedly occurs at the production site it may not be possible to continue the production and the demand cannot be satisfied.

Final remarks

Although there are quite a few uncertainties with the projected production of lithium and demand for lithium for electric vehicles, this study indicates that the possible lithium production could be a limiting factor for the number of electric vehicles that can be produced, and how fast they can be produced. If large parts of the car fleet will run on electricity and rely on lithium based batteries in the coming decades, it is possible, and maybe even likely, that lithium availability will be a limiting factor.

To decrease the impact of this, as much lithium as possible must be recycled and possibly other battery technologies not relying on lithium needs to be developed. It is not certain how big the recoverable reserves of lithium are in the world and estimations in different studies differ significantly. Especially the estimations for brine need to be further investigated. Some estimates include production from seawater, making the reserves more or less infinitely large. We suggest that it is very unlikely that seawater or lakes will become a practical and economic source of lithium, mainly due to the high Mg/Li ratio and low concentrations if lithium, meaning that large quantities of water would have to be processed. Until otherwise is proved lithium reserves from seawater and lakes should not be included in the reserve estimations. Although the reserve estimates differ, this appears to have marginal impact on resulting projections of production, especially in a shorter time perspective. What are limiting are not the estimated reserves, but likely maximum annual production, which is often missed in similar studies.

If electric vehicles with li-ion batteries will be used to a very high extent, there are other problems to account for. Instead of being dependent on oil we could become dependent on lithium if li-ion batteries, with lithium reserves mainly located in two countries. It is important to plan for this to avoid bottlenecks or unnecessarily high prices. Lithium is a finite resource and the production cannot be infinitely large due to geological, technical and economical restraints. The concentration of lithium metal appears to be decreasing, which could make it more expensive and difficult to extract the lithium in the future. To enable a transition towards a car fleet based on electrical energy, other types of batteries should also be considered and a continued development of battery types using less lithium and/or other metals are encouraged. High recycling rates should also be aimed for if possible and continued investigations of recoverable resources and possible production of lithium are called for.

Forget 1984…. 2020 is the apocalypse year

26 01 2017

The crescendo of news pointing to 2020 as the date to watch is growing apace…. it won’t be the year collapse happens, because collapse is a process, not an event; but it will definitely be the year this process starts to become obvious. To people other than followers of this blog at least…!

RIYADH, Saudi ArabiaAccording to the International Monetary Fund, Saudi Arabia’s economy is in danger of collapse as oil prices grow increasingly unstable.

The warning appeared in the “Regional Economic Outlook” for the Middle East and Central Asia published on Oct. 15, an annual report published by IMF economists. Adam Leyland, writing on Oct. 23 for The Independent, explained the grim prognosis for Saudi’s economy, which is almost completely dependent on fossil fuels:

“[T]he IMF said that the kingdom will suffer a negative 21.6 per cent ‘General Government Overall Fiscal Balance’ in 2015 and a 19.4 per cent negative balance in 2016, a massive increase from only -3.4 per cent in 2014.

Saudi Arabia currently has $654.5 billion in foreign reserves, but the cash is disappearing quickly.

The Saudi Arabian Monetary Agency has withdrawn $70 billion in funds managed by overseas financial institutions, and has lost almost $73 billion since oil prices slumped, according to Al-Jazeera. Saudi Arabia generates 90 per cent of its income from oil.”

AND……..

Tax-free living will soon be a thing of the past for Saudis after its cabinet on Monday approved an IMF-backed value-added tax to be imposed across the Gulf following an oil slump.

A 5% levy will apply to certain goods following an agreement with the six-member Gulf Cooperation Council in June last year.

Residents of the energy-rich region had long enjoyed a tax-free and heavily subsidised existence but the collapse in crude prices since 2014 sparked cutbacks and a search for new revenue.

Author Dr Nafeez Ahmed, a Visiting Fellow at Anglia Ruskin University’s Global Sustainability Institute, is making even more waves today, saying………:

“Syria and Yemen demonstrate how climate and energy crises work together to undermine state power and fuel terrorism. 

“Climate-induced droughts ravage agriculture, swell the ranks of the unemployed and destroy livelihoods.  Domestic oil depletion undercuts state revenues, weakening the capacity to sustain domestic subsidies for fuel and food.  As the state is unable to cope with the needs of an increasingly impoverished population, this leads to civil unrest and possibly radicalisation and terrorism. 

“These underlying processes are not isolated to Syria and Yemen.  Without a change of course, the danger is that eventually they will occur inside the US and Europe.”

Failing States, Collapsing Systems: BioPhysical Triggers of Political Violence, authored by Dr Nafeez Ahmed, published by Springer Briefs in Energy includes the following key points…:
  • Global net energy decline is the underlying cause of the decline in the rate of global economic growth.  In the short term, slow or absent growth in Europe and the US is complicit in voter discontent and the success of anti-establishment politicians. 
  • Europe is now a post-peak oil society, with its domestic oil production declining every year since 1999 by 6%.  Shale oil and gas is unlikely to offset this decline. 
  • Europe’s main sources of oil imports are in decline. Former Soviet Union producers, their production already in the negative, are likely to terminate exports by 2030.  Russia’s oil production is plateauing and likely to decline after 2030 at the latest. 
  • In the US, conventional oil has already peaked and is in sharp decline.  The shortfall is being made up by unconventional sources such as tight oil and shale gas, which are likely to peak by 2025. California will continue to experience extensive drought over the coming decades, permanently damaging US agriculture.
  • Between 2020 and 2035, the US and Mexico could experience unprecedented military tensions as the latter rapidly runs down its conventional oil reserves, which peaked in 2006. By 2020, its exports will revert to zero, decimating Mexican state revenues and potentially provoking state failure shortly thereafter.
  • After 2025, Iraq is unlikely to survive as a single state.  The country is experiencing worsening water scarcity, fueling an ongoing agricultural crisis, while its oil production is plateauing due to a combination of mounting costs of production and geopolitical factors.
  • Saudi Arabia will face a ‘perfect storm’ of energy, food and economic shocks most likely before 2030, and certainly within the next 20 years.
  • Egypt will begin to experience further outbreaks of civil unrest leading to escalating state failure after 2021.  Egypt will likely become a fully failed state after 2037.
  • India’s hopes to become a major economic player will falter due to looming food, water and energy crises.  India’s maximum potential domestic renewable energy capacity is insufficient to meet projected demand growth.
  • China’s total oil production is likely to peak in 2020.  Its rate of economic growth is expected to fall continuously in coming decades, while climate change will damage its domestic agriculture, forcing it to rely increasingly on expensive imports by 2022.

I wish Julian Simon could read this….. it seems all our limits to growth chickens are coming home to roost, and very soon now.





What is this ‘Crisis’ of Modernity?

22 01 2017

But why is the economy failing to generate prosperity as in earlier decades?  Is it mainly down to Greenspan and Bernanke’s monetary excesses?  Certainly, the latter has contributed to our contemporary stagnation, but perhaps if we look a little deeper, we might find an additional explanation. As I noted in a Comment of 6 January 2017, the golden era of US economic expansion was the ‘50s and ‘60s – but that era had begun to unravel somewhat, already, with the economic turbulence of the 70s. However, it was not so much Reagan’s fiscal or monetary policies that rescued a deteriorating situation in that earlier moment, but rather, it was plain old good fortune. The last giant oil fields with greater than 30-to-one, ‘energy-return’ on ‘energy-cost’ of exploitation, came on line in the 1980s: Alaska’s North Slope, Britain and Norway’s North Sea fields, and Siberia. Those events allowed the USA and the West generally to extend their growth another twenty years.

This week, there has been an avalanche of articles on Limits to Growth, just not titled so……. it’s almost as though the term is getting stuck in people’s throats, and are unable to pronounce them….

acrooke

Alastair Crooke

This article by former British diplomat and MI6 ‘ranking figure’ Alastair Crooke, is an unpublished article I’ve lifted from the Automatic Earth…… as Raul Ilargi succinctly puts it…:

 

His arguments here are very close to much of what the Automatic Earth has been advocating for years [not to mention DTM’s…], both when it comes to our financial crisis and to our energy crisis. Our Primers section is full of articles on these issues written through the years. It’s a good thing other people pick up too on topics like EROEI, and understand you can’t run our modern, complex society on ‘net energy’ as low as what we get from any of our ‘new’ energy sources. It’s just not going to happen.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Alastair Crooke: We have an economic crisis – centred on the persistent elusiveness of real growth, rather than just monetised debt masquerading as ‘growth’ – and a political crisis, in which even ‘Davos man’, it seems, according to their own World Economic Forum polls, is anxious; losing his faith in ‘the system’ itself, and casting around for an explanation for what is occurring, or what exactly to do about it. Klaus Schwab, the founder of the WEF at Davos remarked  before this year’s session, “People have become very emotionalized, this silent fear of what the new world will bring, we have populists here and we want to listen …”.

Dmitry Orlov, a Russian who was taken by his parents to the US at an early age, but who has returned regularly to his birthplace, draws on the Russian experience for his book, The Five Stages of Collapse. Orlov suggests that we are not just entering a transient moment of multiple political discontents, but rather that we are already in the early stages of something rather more profound. From his perspective that fuses his American experience with that of post Cold War Russia, he argues, that the five stages would tend to play out in sequence based on the breaching of particular boundaries of consensual faith and trust that groups of human beings vest in the institutions and systems they depend on for daily life. These boundaries run from the least personal (e.g. trust in banks and governments) to the most personal (faith in your local community, neighbours, and kin). It would be hard to avoid the thought – so evident at Davos – that even the elites now accept that Orlov’s first boundary has been breached.

But what is it? What is the deeper economic root to this malaise? The general thrust of Davos was that it was prosperity spread too unfairly that is at the core of the problem. Of course, causality is seldom unitary, or so simple. And no one answer suffices. In earlier Commentaries, I have suggested that global growth is so maddeningly elusive for the elites because the debt-driven ‘growth’ model (if it deserves the name ‘growth’) simply is not working.  Not only is monetary expansion not working, it is actually aggravating the situation: Printing money simply has diluted down the stock of general purchasing power – through the creation of additional new, ‘empty’ money – with the latter being intermediated (i.e. whisked away) into the financial sector, to pump up asset values.

It is time to put away the Keynesian presumed ‘wealth effect’ of high asset prices. It belonged to an earlier era. In fact, high asset prices do trickle down. It is just that they trickle down into into higher cost of living expenditures (through return on capital dictates) for the majority of the population. A population which has seen no increase in their real incomes since 2005 – but which has witnessed higher rents, higher transport costs, higher education costs, higher medical costs; in short, higher prices for everything that has a capital overhead component. QE is eating into peoples’ discretionary income by inflating asset balloons, and is thus depressing growth – not raising it. And zero, and negative interest rates, may be keeping the huge avalanche overhang of debt on ‘life support’, but it is eviscerating savings income, and will do the same to pensions, unless concluded sharpish.

But beyond the spent force of monetary policy, we have noted that developed economies face separate, but equally formidable ‘headwinds’, of a (non-policy and secular) nature, impeding growth – from aging populations in China and the OECD, the winding down of China’s industrial revolution,  and from technical innovation turning job-destructive, rather than job creative as a whole. Connected with this is shrinking world trade.

But why is the economy failing to generate prosperity as in earlier decades?  Is it mainly down to Greenspan and Bernanke’s monetary excesses?  Certainly, the latter has contributed to our contemporary stagnation, but perhaps if we look a little deeper, we might find an additional explanation. As I noted in a Comment of 6 January 2017, the golden era of US economic expansion was the ‘50s and ‘60s – but that era had begun to unravel somewhat, already, with the economic turbulence of the 70s. However, it was not so much Reagan’s fiscal or monetary policies that rescued a deteriorating situation in that earlier moment, but rather, it was plain old good fortune. The last giant oil fields with greater than 30-to-one, ‘energy-return’ on ‘energy-cost’ of exploitation, came on line in the 1980s: Alaska’s North Slope, Britain and Norway’s North Sea fields, and Siberia. Those events allowed the USA and the West generally to extend their growth another twenty years.

And, as that bounty tapered down around the year 2000, the system wobbled again, “and the viziers of the Fed ramped up their magical operations, led by the Grand Vizier (or “Maestro”) Alan Greenspan.”  Some other key things happened though, at this point: firstly the cost of crude, which had been remarkably stable, in real terms, over many years, suddenly started its inexorable real-terms ascent.  And from 2001, in the wake of the dot.com ‘bust’, government and other debt began to soar in a sharp trajectory upwards (now reaching $20 trillion). Also, around this time the US abandoned the gold standard, and the petro-dollar was born.

Well, the Hill’s Group, who are seasoned US oil industry engineers, led by B.W. Hill, tell us – following their last two years, or so, of research – that for purely thermodynamic reasons net energy delivered to the globalised industrial world (GIW) per barrel, by the oil industry (the IOCs) is rapidly trending to zero. Note that we are talking energy-cost of exploration, extraction and transport for the energy-return at final destination. We are not speaking of dollar costs, and we are speaking in aggregate. So why should this be important at all; and what has this to do with spiraling debt creation by the western Central Banks from around 2001?

The importance? Though we sometimes forget it, for we now are so habituated to it, is that energy is the economy.  All of modernity, from industrial output and transportation, to how we live, derives from energy – and oil remains a key element to it.  What we (the globalized industrial world) experienced in that golden era until the 70s, was economic growth fueled by an unprecedented 321% increase in net energy/head.  The peak of 18GJ/head in around 1973 was actually of the order of some 40GJ/head for those who actually has access to oil at the time, which is to say, the industrialised fraction of the global population. The Hill’s Group research  can be summarized visually as below (recall that these are costs expressed in energy, rather than dollars):

[This study was also covered here on Damnthematrix starting here…]

But as Steve St Angelo in the SRSrocco Reports states, the important thing to understand from these energy return on energy cost ratios or EROI, is that a minimum ratio value for a modern society is 20:1 (i.e. the net energy surplus available for GDP growth should be twenty times its cost of extraction). For citizens of an advanced society to enjoy a prosperous living, the EROI of energy needs to be much higher, closer to the 30:1 ratio. Well, if we look at the chart below, the U.S. oil and gas industry EROI fell below 30:1 some 46 years ago (after 1970):

 


Source: https://srsroccoreport.com/the-coming-breakdown-of-u-s-global-markets-explained-what-most-analysts-missed/

“You will notice two important trends in the chart above. When the U.S. EROI ratio was higher than 30:1, prior to 1970, U.S. public debt did not increase all that much.  However, this changed after 1970, as the EROI continued to decline, public debt increased in an exponential fashion”. (St Angelo).

In short, the question begged by the Hill’s Group research is whether the reason for the explosion of government debt since 1970 is that central bankers (unconsciously), were trying to compensate for the lack of GDP stimulus deriving from the earlier net energy surplus.  In effect, they switched from flagging energy-driven growth, to the new debt-driven growth model.

From a peak net surplus of around 40 GJ  (in 1973), by 2012, the IOCs were beginning to consume more energy per barrel, in their own processes (from oil exploration to transport fuel deliveries at the petrol stations), than that which the barrel would deliver net to the globalized industrial world, in aggregate.  We are now down below 4GJ per head, and dropping fast. (The Hill’s Group)

Is this analysis by the Hill’s Group too reductionist in attributing so much of the era of earlier western material prosperity to the big discoveries of ‘cheap’ oil, and the subsequent elusiveness of growth to the decline in net energy per barrel available for GDP growth?  Are we in deep trouble now that the IOCs use more energy in their own processes, than they are able to deliver net to industrialised world? Maybe so. It is a controversial view, but we can see – in plain dollar terms – some tangible evidence fo rthe Hill’s Groups’ assertions:

 


Source: https://srsroccoreport.com/wp-content/uploads/2016/08/Top-3-U.S.-Oil-Companies-Free-Cash-Flow-Minus-Dividends.png

(The top three U.S. oil companies, ExxonMobil, Chevron and ConocoPhillips: Cash from operations less Capex and dividends)

Briefly, what does this all mean? Well, the business model for the big three US IOCs does not look that great: Energy costs of course, are financial costs, too.  In 2016, according to Yahoo Finance, the U.S. Energy Sector paid 86% of their operating income just to service the interest on the debt (i.e. to pay for those extraction costs). We have not run out of oil. This is not what the Hill’s Group is saying. Quite the reverse. What they are saying is the surplus energy (at a ratio of now less than 10:1) that derives from the oil that we have been using (after the energy-costs expended in retrieving it) – is now at a point that it can barely support our energy-driven ‘modernity’.  Implicit in this analysis, is that our era of plenty was a one time, once off, event.

They are also saying that this implies that as modernity enters on a more severe energy ‘diet’, less surplus calories for their dollars – barely enough to keep the growth engine idling – then global demand for oil will decline, and the price will fall (quite the opposite of mainstream analysis which sees demand for oil growing. It is a vicious circle. If Hills are correct, a key balance has tipped. We may soon be spending more energy on getting the energy that is required to keep the cogs and wheels of modernity turning, than that same energy delivers in terms of calorie-equivalence.  There is not much that either Mr Trump or the Europeans can do about this – other than seize the entire Persian Gulf.  Transiting to renewables now, is perhaps too little, too late.

And America and Europe, no longer have the balance sheet ‘room’, for much further fiscal or monetary stimulus; and, in any event, the efficacy of such measures as drivers of ‘real economy’ growth, is open to question. It may mitigate the problem, but not solve it. No, the headwinds of net energy per barrel trending to zero, plus the other ‘secular’ dynamics mentioned above (demography, China slowing and technology turning job-destructive), form a formidable impediment – and therefore a huge political time bomb.

Back to Davos, and the question of ‘what to do’. Jamie Dimon, the CEO of  JPMorgan Chase, warned  that Europe needs to address disagreements spurring the rise of nationalist leaders. Dimon said he hoped European Union leaders would examine what caused the U.K. to vote to leave and then make changes. That hasn’t happened, and if nationalist politicians including France’s Marine Le Pen rise to power in elections across the region, “the euro zone may not survive”. “The bottom line is the region must become more competitive, Dimon said, which in simple economic terms means accept even lower wages. It also means major political overhauls: “I say this out of respect for the European people, but they’re going to have to change,” he said. “They may be forced by politics, they may be forced by new leadership.”

A race to the bottom in pay levels?  Italy should undercut Romanian salaries?  Maybe Chinese pay scales, too? This is politically naïve, and the globalist Establishment has only itself to blame for their conviction that there are no real options – save to divert more of the diminished prosperity towards the middle classes (Christine Lagarde), and to impose further austerity (Dimon). As we have tried to show, the era of prosperity for all, began to waver in the 70s in America, and started its more serious stall from 2001 onwards. The Establishment approach to this faltering of growth has been to kick the can down the road: ‘extend and pretend’ – monetised debt, zero, or negative, interest rates and the unceasing refrain that ‘recovery’ is around the corner.

It is precisely their ‘kicking the can’ of inflated asset values, reaching into every corner of life, hiking the cost of living, that has contributed to making Europe the leveraged, ‘high cost’, uncompetitive environment, that it now is.  There is no practical way for Italians, for example, to compete with ‘low cost’ East Europe, or  Asia, through a devaluation of the internal Italian price level without provoking major political push-back.  This is the price of ‘extend and pretend’.

It has been claimed at Davos that the much derided ‘populists’ provide no real solutions. But, crucially, they do offer, firstly, the hope for ‘regime change’ – and, who knows, enough Europeans may be willing to take a punt on leaving the Euro, and accepting the consequences, whatever they may be. Would they be worse off? No one really knows. But at least the ‘populists’ can claim, secondly, that such a dramatic act would serve to escape from the suffocation of the status quo. ‘Davos man’ and woman disdain this particular appeal of ‘the populists’ at their peril.

Hi all.

The global economic slowdown has politicians and economists baffled. TARP, QE, ZIRP and NIRP have failed. What is going on? Well, we were warned decades ago and refused to heed. We have reached the limits of our planet’s ability to provide growth and like peak oil, is being hidden by the largest debt bubble in history. Continuing the pursuit of growth will only exacerbate our environmental, ecological, social and economic problems which, are already severe.

The “Jobs and Growth” mantra of Australia’s recent election was never questioned by the main stream media. (MSM) Until MSM journalists realize the environmentally destructive and civilization destroying nature of compound growth, our problems will only exacerbate and and the probability of the bulk of humanity surviving more than a few decades more which, is already approaching zero, will only further reduce.

If MSM journalists think that they have got reserved places in the elite’s doomsday bunkers and yes, they do exist, aka survival shelters then, they have got rocks in their heads. The corporate controlled MSM journalists must realize that they are being used, find some courage, rebel and hold those that are destroying our world to account. For them not to puts them in the same criminal class as the greedy psychopathic ruling elites that are literally killing us.

The Day After…….

3 07 2016

Australia has voted, and we have business as usual. I shouldn’t be surprised of course. The ignorant electorate has spoken……

What the ignorant electorate had to choose from was Blue Jobs and Growth (BJG), Red Jobs and Growth (RJG), Green Jobs and Growth (GJG) and now the X Men (and one woman). The X men, Nick Xenophon’s Party, also want jobs and growth (XJG), specifically in Whyalla.

As I said to someone who congratulated themselves for campaigning so well, at the end of the day, we’ll have business as usual. At the end of the day, we also appear to be heading for a hung parliament, possibly the best result under the circumstances, none of them deserve to be in power….hungparliament

The lack of understanding of the true future in store, the kow towing to the Matrix, the influence of the Murdock Press, and the sheer momentum of the monetary system has led us to utter lack of vision.

Even with their best ever campaign performance, the Greens hardly made a dent. When I stood for election in 2001, I was thoroughly congratulated for getting 6% of the vote. I was bitterly disappointed. A solid month out of my life, campaigning every day, for 6%..? And here we are, fifteen years later, and the vote’s gone up by 4% (more in some seats obviously..), and the Greens are still congratulating themselves. In one election, the X Men have done better than the Greens have done in four or five….. you’d think that by now it’s clear the electorate does not care. The Greens’ message has reached saturation point, and unless you’re a dyed in the wool greenie, you ain’t gonna vote for them, not even when thoroughly pissed off with the rest.

hungdemocracyEven if they fall over the line in Batman and Melbourne Ports, their influence will be very limited, the reds and the blues will just gang up on them…. The Greens’ leader Richard Di Natale says Australians are looking for a change, but all they’re doing is more of the same only a different colour. The change we need, as we fast run out of time, is on such a scale nobody even dares to contemplate it……

In the last few days of the election campaign, everywhere I went on the internet was peppered with Greens ads. I was impressed actually. The three word slogan (which is about all the electorate understands) “Save the Reef” was everywhere. Clearly, Australians don’t care if the reef dies. All they care about are Jobs and Growth. They don’t, seemingly, even care about green jobs and growth much at all.

Malcolm Turncoat may be finished over this result. He backstabbed the Abbott over bad polls, and now with the poll that really counts not coming good for him, possibly a ‘worse’ Senate (for the BJG Party) than before the double dissolution, a leadership challenge is in my view on the cards. God help us if the Abbott makes a comeback, he was by far the worst PM we’ve ever had, and that’s really saying something….

Not that I care. I realised the other day just how much ‘past caring’ I am….. apart from what happens to my family and closest friends, I’ve stopped caring.

The way things are going, by 2020 we’ll all be driving over cliffs in solar powered electric cars. China appears to be heading for a depression, the Saudi oil industry has laid off 50,000 to 77,000 workers, many of whom have not been paid for several months, and now, according to the IMF, the Brexit vote will have negative repercussions that will spread beyond the U.K. and Europe to the global economy. Good. All these good outcomes might slow emissions down.

How the Australian Jobs and Growth Parties deal with these issues will be mildly interesting, but nothing will happen ’til we have a major banking collapse, and that might even begin with Deutsche Bank, described by some as the world’s most systemically dangerous bank…….

How the jobs and growth parties will fund their promises under a banking collapse will be interesting to watch. The similarity between what happened to Lehhman in 2008 and DB today is simply amazing….. by then, jobs and growth will be a thing of the past, no matter what colour.

As far as I’m concerned, we’re on our own, and we should be actively planning for this. Plan your future, then work your plan…….. Voting no longer counts for anything, nobody elected in Parliament knows what they are doing.

ME?  Cynical…?  Don’t make me laugh……..





Jobs and growth

26 05 2016

Many moons ago, I ‘met’ this guy on The Conversation who called himself Harquebus…. which is French (more or less) for a flintstock rifle.  Why he picked that word as his internet identity, not even I know, but what I do know is that we agreed on nearly everything…!  He found me by following the many links to DTM I had left behind, and now, as a result, I get a sort of ‘newsletter’ from him.  Here is his latest.

Lots of links, as usual….  enjoy.

Hi all.

We are less than three weeks into the Australian federal election campaign which, was called because the Australian Building Construction Commission legislation could not pass the senate. So far I have not heard it mentioned once. What I have heard ad-nauseam is the slogan, “jobs and growth”.

Our Prime Minister, his deputy and ministers can not string two sentences together without including this slogan. In the myriad of interviews that I have seen so far during this campaign, not one journalist has queried the need for pursuing this destructive ideology.

Rather than create jobs, no one has instead considered reducing populations. Not only would it reduce unemployment and put more in peoples hands and pockets, it will also reduce pollution, environmental destruction, urban sprawl, traffic jams, smog, inequality and poverty etc.

“Jobs and growth” is not being called for by the general population. It is being promoted by the very small minority that benefit from it. The rest of us will suffer from it until the point of no return when, rich and poor alike will perish because of it.

There are no vast habitable expanses left to inhabit, there are no large quantities of easily accessible resources to exploit and there is no cheap and abundant energy left to provide the growth that we have seen these past two centuries.

Every politician using the slogan “jobs and growth” is displaying their ignorance of the exponential function, the limited finite resources that are available to us and the consequences of our attack on the natural world.

Do you really want more traffic jams, more over crowding, more urban sprawl, limited access to resources, more pollution, more inequality, more poverty, more CO2, depleted fish stocks and more unemployment etc. until, we can not sustain ourselves any longer and have to endure the inevitable bloody consequences? This is what those that pursue growth at any cost will bring you.

I urge all journalists on my list, for all of our sake, query this destructive ideology before it is too late. As it is, the damage already done will take centuries to recover, humans surviving or not.

I have included an attachment listing various alternative news sources. A lot are already on my reading list, some I come across regularly and a few I have never heard of before.

If you are turned off by the endless trivia and propaganda being spoon fed to us by the corporate controlled main stream media (MSM), please take a look. The differences between MSM and the alternative media are large.

Here again is my list of various articles along with excerpts.

Avagoodwun.

Cheers.

Another study on the ERoEI of solar PV

10 05 2016

Originally posted by Euan Mearns on his blog Energy Matters, this study makes Pedro Prieto’s look very good….. the differences in ERoEI between the two studies must be a function of the difference in latitude between Spain and the UK, and even possibly by the fact that as the ERoEI of fossil fuels drops like a stone, the ERoEI of renewables must follow suit, as they rely entirely on the former.  Is Mearns a fan of nuclear power?  You make up your mind….

As Fort McMurray burns, and its smoke plume reaches the East coast of the USA, it’s occurred to me that the inevitable efforts and energy smoke-plume-from-fort-mcmurray-fire-reaches-us-east-coastrequired to rebuild it once the fire is out (IF, that is, it doesn’t reach the tar sands and sets them alight…), should be included in the ERoEI of fossil fuels.  Whilst it’s impossible to say Climate Change caused the fire in Alberta Canada, it’s impossible to not make the connection that the only reason it was over 20°C when the fire started was entirely down to the jetstream going haywire because of the arctic melt……  in fact, the energy spent rebuilding destroyed infrastructure caused by Climate Change anywhere should now be included in the ERoEI of fossil fuels….

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

A new study by Ferroni and Hopkirk [1] estimates the ERoEI of temperate latitude solar photovoltaic (PV) systems to be 0.83. If correct, that means more energy is used to make the PV panels than will ever be recovered from them during their 25 year lifetime. A PV panel will produce more CO2 than if coal were simply used directly to make electricity. Worse than that, all the CO2 from PV production is in the atmosphere today, while burning coal to make electricity, the emissions would be spread over the 25 year period. The image shows the true green credentials of solar PV where industrial wastelands have been created in China so that Europeans can make believe they are reducing CO2 emissions (image credit Business Insider).

I have been asked to write a post reviewing the concept of energy return on energy invested (ER0EI) and as a first step in that direction I sent an email to my State-side friends Charlie Hall, Nate Hagens and David Murphy asking that they send me recent literature. The first paper I read was by Ferruccio Ferroni and Robert J. Hopkirk titled Energy Return on Energy Invested (ERoEI) for photovoltaic solar systems in regions of moderate insolation [1] and the findings are so stunning that I felt compelled to write this post immediately.

So what is ERoEI? It is simply the ratio of energy gathered to the amount of energy used to gather the energy (the energy invested):

ERoEI = energy gathered / energy invested

Simple, isn’t it? Well it’s not quite so simple as it appears at first sight. For example, using PV to illustrate the point, the energy gathered will depend on latitude, the amount of sunshine, the orientation of the panels and also on the lifetime of the panels themselves. And how do you record or measure the energy invested? Do you simply measure the electricity used at the PV factory, or do you include the energy consumed by the workers and the miners who mined the silicon and the coal that is used to make the electricity? Ferroni and Hopkirk go into all of these details and come up with an ERoEI for temperate latitude solar PV of 0.83. At this level, solar PV is not an energy source but is an energy sink. That is for Switzerland and Germany. It will be much worse in Aberdeen!

Why is ERoEI important? It is a concept that is alien to most individuals, including many engineers, energy sector employees, academics and policy makers. The related concept of net energy is defined as:

Net Energy = ERoEI – 1 (where 1 is the energy invested)

Net energy is the surplus energy left over from our energy gathering activities that is used to power society – build hospitals, schools, aircraft carriers and to grow food. In the past the ERoEI of our primary energy sources – oil, gas and coal – was so high, probably over 50, that there was bucket loads of cheap energy left over to build all the infrastructure and to feed all the people that now inhabit The Earth. But with the net energy equation for solar PV looking like this:

0.83-1 = -0.17

….. Brussels we have a problem!

So how can it be possible that we are managing to deploy devices that evidently consume rather than produce energy? The simple answer is that our finance system, laws and subsidies are able to bend the laws of physics and thermodynamics for so long as we have enough high ERoEI energy available to maintain the whole system and to subsidise parasitic renewables. Try mining and purifying silicon using an electric mining machine powered by The Sun and the laws of physics will re-establish themselves quite quickly.

In very simple terms, solar PV deployed in northern Europe can be viewed as coal burned in China used to generate electricity over here. All of the CO2 emissions, that underpin the motive for PV, are made in China. Only in the event of high energy gain in the PV device would solar PV reduce CO2 emissions. More on that later.

Energy Return

The calculations are all based on the energy produced by 1 m^2 of PV.

Theoretical calculations of what PV modules should generate made by manufacturers do not take into account operational degradation due to surface dirt. Nor do they take into account poor orientation, unit failure or breakage, all of which are quite common.

The actual energy produced using Swiss statistics works out at 106kWe/m^2 yr

We then also need to know how long the panels last. Manufacturers claim 30 years while empirical evidence suggests a mean scrapage age of only 17 years in Germany. Ferroni and Hopkirk use a generous 25 year unit life.

Combining all these factors leads to a number of 2203kWe/m^2 for the life of a unit.

Energy Invested

The energy invested calculation is also based on 1 m^2 of panel and uses mass of materials as a proxy for energy consumed and GDP energy intensity as a proxy for the labour part of the equation.

Two different methods for measuring energy invested are described:

  • ERoEI(IEA)
  • ERoEI(Ext)

Where IEA = methodology employed by the International Energy Agency and Ext = extended boundary as described by Murphy and Hall, 2010 [2,3]. The difference between the two is that the IEA is tending to focus on the energy used in the factory process while the extended methodology of Murphy and Hall, 2010 includes activities such as mining, purifying and transporting the silicon raw material.

In my opinion, Ferroni and Hopkirk correctly follow the extended ERoEI methodology of Murphy and Hall and include the following in their calculations:

  • Materials to make panels but also to erect and install panels
  • Labour at every stage of the process from mining manufacture and disposal
  • Manufacturing process i.e. the energy used in the various factories
  • Faulty panels that are discarded
  • Capital which is viewed as the utilisation of pre-existing infrastructure and energy investment
  • Integration of intermittent PV onto the grid

And that gives us the result of ERoEI:

2203 / 2664 kW he/m^2 = 0.83

The only point I would question is the inclusion of the energy cost of capital. All energy produced can be divided into energy used to gather energy and energy for society and I would question whether the cost of capital does not fall into the latter category?

But there appears to be one major omission and that is the energy cost of distribution. In Europe, about 50% of the cost of electricity (excluding taxes) falls to the grid construction and maintenance. If that was to be included it would make another serious dent in the ERoEI.

This value for ERoEI is lower than the value of 2 reported by Prieto and Hall [4] and substantially lower that the values of 5 to 6 reported by the IEA [5]. One reason for this is that the current paper [1] is specifically for temperate latitude solar. But Ferroni and Hopkirk also detail omissions by the IEA as summarised below.

IEA energy input omissions and errors

a) The energy flux across the system boundaries and invested for the labour is not included.
b) The energy flux across the system boundaries and invested for the capital is not included.
c) The energy invested for integration of the PV-generated electricity into a complex and flexible electricity supply and distribution system is not included (energy production does not follow the needs of the customer).
d) The IEA guidelines specify the use of “primary energy equivalent” as a basis. However, since the energy returned is measured as secondary electrical energy, the energy carrier itself, and since some 64% to 67% of the energy invested for the production of solar-silicon and PV modules is also in the form of electricity (Weissbach et al., 2013) and since moreover, the rules for the conversion from carrier or secondary energy back to primary energy are not scientifically perfect (Giampietro and Sorman, 2013), it is both easier and more appropriate to express the energy invested as electrical energy. The direct contribution of fossil fuel, for instance in providing energy for process heating, also has to be converted into secondary energy. The conversion from a fossil fuel’s internal chemical energy to electricity is achieved in modern power plants with an efficiency of 38% according to the BP statistic protocol (BP Statistical Review of World Energy, June 2015). In the present paper, in order to avoid conversion errors, we shall continue to use electrical (i.e. secondary) energy in kW he/m2 as our basic energy unit.
e) The recommended plant lifetime of 30 years, based on the experiences to date, must be regarded as unrealistic.
f) The energy returned can and should be based on actual experimental data measured in the field. Use of this procedure will yield values in general much lower than the electricity production expected by investors and politicians.

Of those I’d agree straight off with “a”, “c” and “f”. I’m not sure about “b” and “e” I’m sure this will be subject to debate. “d” is a complex issue and is in fact the same one described in my recent post EU and BP Renewable Electricity Accounting Methodologies. I agree with Ferroni and Hopkirk that units of electricity should be used throughout but if the IEA have grossed up the electricity used to account for thermal losses in power stations then this would increase their energy invested and suppress not inflate their estimates of ERoEI. Hence this is a point that needs to be clarified.

Environmental impacts

The main reason for deploying solar PV in Europe is to lower CO2 emissions. The European Commission and most European governments have been living in cloud cuckoo land allowing CO2 intensive industries to move to China, lowering emissions in Europe while raising emissions in China and making believe that importing steel from China somehow is emissions free.

The example of solar PV brings this into sharp focus. Assuming the main energy input is from coal (and low efficiency dirty coal at that) and with ERoEI <1, making electricity from solar PV will actually create higher emissions than had coal been used directly to make electricity for consumption in the first place. But it’s a lot worse than that. All of the emissions associated with 25 years of electricity production are in the atmosphere now making global warming much worse than it would otherwise have been without the PV.

And it gets even worse than that! The manufacture of PV panels involves lots of nasty chemicals too:

Many potentially hazardous chemicals are used during the production of solar modules. To be mentioned here is, for instance, nitrogen trifluoride (NF3), (Arnold et al., 2013), a gas used for the cleaning of the remaining silicon-containing contaminants in process chambers. According to the IPCC (Intergovernmental Panel on Climate Change) this gas has a global warming potential of approximately 16600 times that of CO2. Two other similarly undesirable “greenhouse” gases appearing are hexafluoroethane (C2F6) and sulphur hexafluoride (SF6).

And

The average weight of a photovoltaic module is 16 kg/m2 and the weight of the support system, inverter and the balance of the system is at least 25 kg/m2 (Myrans, 2009), whereby the weight of concrete is not included. Also, most chemicals used, such as acids/ bases, etchants, elemental gases, dopants, photolithographic chemicals etc. are not included, since quantities are small. But, we must add hydrochloric acid (HCl): the production of the solar- grade silicon for one square meter of panel area requires 3.5 kg of concentrated hydrochloric acid.

Comparison with nuclear

The paper offers some interesting comparisons with nuclear power. Looking first at materials used per unit of electricity produced:

  • PV uses 20.2 g per kW he (mainly steel aluminium and copper)
  • A nuclear power station uses 0.31 g per kW he (mainly steel) for a load factor of 85%

kW he = kilowatt hours electrical

Looking at labour, the authors observe:

The suppliers involved in the renewable energies industry advertise their capability to create many new jobs.

While of course the best forms of energy use as little labour as possible. At the point where ERoEI reaches 1, everyone is engaged in gathering energy and society as we know it collapses!

  • Solar PV creates 94.4 jobs per MW installed, adjusted for capacity factor.
  • Nuclear creates 13 jobs per MW installed covering construction, operation and decommissioning.

This may seem great to the politicians but it’s this inefficiency that makes solar PV expensive and kills the ERoEI. And looking at capital costs:

  • Solar PV needs CHF 6000 per kW installed (CHF = Swiss Franc)
  • Nuclear power CHF 5500 per kW installed

But normalising for capacity factors of 9% for solar and 85% for nuclear we get for effective capacity:

66,667 / 6471 = 10.3

Solar PV is 10 times more capital intensive than nuclear.

Energy transformation

When ERoEI approaches or goes below 1 we enter the realm of energy transformation which is quite common in our energy system. For example, converting coal to electricity we lose approximately 62% of the thermal energy. Converting coal and other raw materials into a PV panel may in certain circumstances make some sense. For example PV and a battery system may provide African villages with some electricity where there is little hope of ever getting a grid connection. Likewise for a mountain cabin. Individuals concerned about blackouts may also consider a PV battery system as a backup contingency.

But as a means of reducing CO2 emissions PV fails the test badly at temperate latitudes. It simply adds cost and noise to the system. In sunnier climates the situation will improve.

Concluding comments

The findings of this single study suggest that deploying solar PV at high latitudes in countries like Germany and the UK is a total waste of time, energy and money. All that is achieved is to raise the price of electricity and destabilise the grid. Defenders of RE and solar will point out that this is a single paper and there are certainly some of the inputs to Ferroni and Hopkirk that are open to debate. But there are reasons to believe that the findings are zeroing in on reality. For example Prieto and Hall found ERoEI for solar PV = 2. Looking only at cloudy, high temperate latitudes will substantially degrade that number.

And you just need to look at the outputs as shown below. Solar PV produces a dribble in winter and absolutely nothing at the 18:00 peak demand. There is a large financial cost and energy cost to compensate for this that RE enthusiasts dismiss with a wave of the arm.

Figure 1 From UK Grid Graphed. The distribution of solar production in the UK has grown 7 fold in 4 years. But 7 times a dribble in winter is still a dribble.  The large amount of embodied energy in these expensive devices does no work for us at all when we need it most.

Energy Matters has a good search facility top right. Insert solar pv and I was surprised to find how many articles Roger and I have written and they all more or less reach the same conclusions. I have added these links at the end of the post.

Figure 2 A typical solar installation in Aberdeen where the panels are on an east facing roof leaving the ideal south facing roof empty. This is a symbol of ignorance and stupidity that also pervades academia. Has anyone seen a University that does not have solar PV deployed? I’ve heard academics argue that orientation does not matter in Scotland, and they could be right. I dare say leaving the panels in their box would make little difference to their output. Academics, of course, are increasingly keen to support government policies. Note that sunny days like this one are extremely rare in Aberdeen. And in winter time, the sun rises about 10:00 and sets around 15:00.

Two years ago I fulminated about the random orientation of solar panels in Aberdeen in a post called Solar Scotland. And this random orientation will undoubtedly lead to serious degradation of the ERoEI. PV enthusiasts will no doubt assume that all solar PV panels are optimally orientated in their net energy analysis while in the real world of Ferroni and Hopkirk, they are not. A good remedy here would be to remove the feed in tariffs of systems not optimally deployed while ending future solar PV feed in tariffs all together.

But how to get this message heard at the political level? David MacKay’s final interview was very revealing:

The only reason solar got on the table was democracy. The MPs wanted to have a solar feed-in-tariff. So in spite of the civil servants advising ministers, ‘no, we shouldn’t subsidise solar’, we ended up having this policy. There was very successful lobbying by the solar lobbyists as well. So now there’s this widespread belief that solar is a wonderful thing, even though … Britain is one of the darkest countries in the world.

If the politicians do not now listen to the advice of one of the World’s most famous and respected energy analysts then I guess they will not listen to anyone. But they will with time become increasingly aware of the consequences of leading their electorate off the net energy cliff.
