The study is based on an extensive list of references. A content analysis was carried out of academic literature and industry reports devoted to both the latest trends in the development of the energy sector and the economy of rare-earth elements. The main emphasis in this study is placed on the relationship between the energy sector and the REM market in order to determine whether the demand for metals and, in particular, for rare-earth metals can be influenced by progressive transformations in the global energy sector or not.
We attempt to encompass the main trends and issues related to the topic discussed and to move consistently from the world’s experience toward Russian «unexplored reality» to answer the questions raised in the research. To get insight into the Russian intentions related to the energy transition trends, we provide a critical analysis of the current situation, as well as observe governmental plans, strategies, programs and agendas. The data about the production of «green» technologies are rather fragmented and unsystematic. To achieve a common vision about current plans and intentions, and to collect quantitative data about particular technologies (discussed in the research) to provide reliable forecasting estimates, plenty of sources were involved, including both scientific and journalistic.
2.1. Global Trends in the Energy Sector and Criticality of Rare-Earth Metals
Currently, processes related to the global energy transition are becoming more intensive [
1,
40]. There is a range of different approaches to defining the term “energy transition” (
Figure 2). This study discusses energy transition as a shift in emphasis from the use of energy that is mainly derived from such carbon-based fuels as coal and oil to the use of energy from such low-carbon sources as natural gas and renewables. One of the important trends taken into considerationin in this case is the fact that the demand for and applications of green technologies (wind turbines, electric vehicles, etc.) are expanding.
The role of fossil fuels in the pattern of demand for energy sources has begun to be gradually redefined. In 2019, the share of oil, coal, and natural gas in the global energy mix decreased by 6.1, 3.7, and 14.8% compared to 2018, respectively, and the growth in energy consumption in the world was provided only by alternative energy sources [
5,
43]. According to BP scenarios reflected in The Energy Outlook, the structure of the energy balance will radically change by 2050 in favor of the prevailing share of renewable energy sources (
Table 1) [
44].
According to the World Energy Council (WEC), the sharp decline in demand for traditional energy sources in 2020 has been a driver for reallocating capital in favor of digital solutions and environmental sustainability [
41]. The Moody’s rating agency named COVID-19 as one of the main reasons for the accelerated transition to green energy. This fact was linked with the revision of corporate policies in the sectors connected with hydrocarbons, changes in consumer behavior in key energy markets, and adopting measures aimed at promoting the recovery of the global economy, with the environmental component being taken into account [
40].
According to DNV GL Energy Transition Outlook 2020, the share of oil and coal in the global energy mix will gradually decrease [
4]. At the same time, the shares of solar and wind energy production will significantly increase. According to the same report (DNV GL Energy Transition Outlook 2020), electric vehicles are expected to reach 100% of global car sales by 2040. In view of this, it can be stated that new trends will create a demand for green technologies.
Figure 3 presents information on changes in oil prices and the volume of investments in the global energy transition. It is worth noting that there is an inverse relationship between these parameters [
45,
46]. Despite the current problems that arose in the global oil and gas industry and the general decline in the development of global economic systems, it can be noted that investments in energy transformation processes only increased, and amounted to
$330 billion (an increase of 11% compared to 2014). In the same period, the main provisions of the Paris Agreement were approved. By 2020, the volume of investments in the global energy transition reached
$501.3 billion, growing by 9% compared to 2019 and by 113% compared to 2010 [
46].
It can be stated that the processes associated with the energy transition can be witnessed all over the world: the production of green technologies is intensifying, plans are being made to reduce the negative impact on the environment, and it is planned to improve energy and resource efficiency. At the same time, it should be understood what exactly lies behind these transformations and how they can affect the future development of global markets, particularly those for metals.
The main drivers for the implementation of the global energy transition are considered to be such factors as government regulation and the availability of technology [
47]. The former is directly related to legal regulation, institutional conditions, funding opportunities for special programs and projects, and so forth. The latter is associated with the availability of materials without which the creation of progressive technologies is simply not possible. It is known that environmentally friendly technologies require much more metals for their production than their counterparts that rely on fossil fuels [
48].
There is an opinion that the global energy transition may cause a depletion of the key resources of the earth, which will only be accelerated by the plans to use metals more intensively [
49]. This is relevant not only for rare-earth metals. Minerals such as nickel, copper, cobalt, lithium, and natural graphite are also among the materials widely used in the green industry. However, due to their availability, there is no concern over their supply being unsustainable [
50].
Rare-earth metals are known for their high electrical conductivity, lightness, and strong magnetic properties. All this makes REMs an integral part of clean energy. These metals are successfully applied as raw materials for the production of permanent magnets, which are widely used in generators for wind turbines and engines for electric vehicles [
14,
15,
16,
17]. Zhou et al. (2017) provided information on the average consumption of individual elements in manufacturing various green technologies [
11]. To produce wind turbines, significant amounts of such elements as neodymium and dysprosium are required; for the production of fluorescent lamps, smaller amounts of elements are required, but their range is bigger and includes lanthanum, cerium, europium, yttrium, neodymium, and terbium [
13]. According to IRENA estimates, there is five times more metals and minerals (lithium, nickel, cobalt, zinc, rare-earth metals, etc.) in electric vehicles compared to conventional cars (173 kg per unit versus 34 kg) [
51]. For the production of one wind turbine, more than 30 kg of these valuable components is required [
18].
Despite all the difficulties in obtaining rare-earth metals that are associated with the geological features of deposits and the complexity of processes required to produce value-added products using REMs (required in the production of modern «green» technologies—oxides, magnets, etc.), there are currently no substitutes that could replace these metals [
18]. The heightened interest in the search for so-called alternative materials was caused by the rare-earth metals crisis that covered the period 2010–2011 [
52,
53,
54].
According to the Technology Metals Research, prior to the crisis, magnets used in wind turbines cost
$80,000 per unit. Under the influence of the rapid rise in prices for rare-earth metals in 2011, similar products began to cost
$500,000 and more (an increase of more than 520%) [
18]. As the pricing environment stabilized, global wind turbine companies began to rethink their supply chain strategies. A number of companies completely abandoned the use of rare-earth components in their products. For example, Siemens eliminated dysprosium from the production of turbines, and the well-known General Electrics switched to “old” transmission technologies to eliminate possible risks of a failure in the supply of rare-earth metals in the future [
18].
In the United States, special studies are being carried out, the purpose of which is to reduce the dependency of the national economy on neodymium-dysprosium magnets and to switch to using its own resources. Since the United States does not have significant reserves of dysprosium, there is only one way out, which is to replace this element with another with similar properties. Cerium—the most common element from the group of rare-earth metals—is being tested as a substitute. However, it does not have the same strong magnetic properties as dysprosium and neodymium do. Therefore, the magnets that are planned to be produced in the future will, a priori, be inferior to their competitors in terms of characteristics [
18].
While some companies are striving to abandon the use of REMs in order to neutralize possible losses from geopolitical risks, others, on the contrary, express their readiness to use them. For example, the largest oil and gas companies begin to show interest in new, or transition materials. According to a BP survey, rare-earths, along with cobalt, natural graphite, and lithium, are “key minerals” for the energy transition. BP collects data on rare-earths stock and production dynamics in order to predict available sources of supply in the future [
5].
In 2021, Norway, one of the leaders in the global oil and gas industry, announced its intention to reorient from deep-sea oil and gas production to deep-water mining of metals, in particular rare-earth metals. The reason for this is the growing demand for such green technologies as electric vehicles, solar power plants, and wind turbines. Japan and China are developing similar plans. The United Nations International Seabed Authority (ISA), which regulates seabed mining in international waters, has approved 30 exploration contracts with China [
55,
56].
Rare-earths are expected to play an increasing role in the world’s resistance to global warming in the long term, and for good reason. According to forecasts by the International Energy Agency (IEA), in order to limit global warming to 2 °C, renewable energy should generate half of the electricity on the planet in 20 years. In one of the most likely scenarios, IEA makes the assumption that solar and wind energy will have to jointly generate more than 6000 TWh, which is more than six times the demand that existed at the turn of 2013–2015. Moreover, manufacturers of electric vehicles must increase production volumes by 80% annually [
18].
Of interest are studies carried out by the Massachusetts University of Technology, according to which for a full transition to green technologies (wind turbines, electric vehicles) over the next 25 years, it will be necessary to increase the production of neodymium by 700% and that of dysprosium by 2600% [
18]. The problem is that the rate of annual growth in the production of these metals does not exceed 6–8%. Alonso et al. predicts that 2035 demand for dysprosium will be over 2500% the supply of its metal in 2010 [
57].
Studies by the U.S. Department of Energy and the European Union confirm the thesis that the world will soon face the problem of a shortage of necessary materials to implement the planned environmental changes. The report “Securing Materials for Emerging Technologies” (APS Physics) states that the lack of required materials can significantly “slow down the introduction of alternative advanced energy technologies” [
58]. This means that without strengthening the supply chain of REMs and other metals, the world will be forced to abandon its plans for the energy transition in favor of preserving the dominant role of fossil fuels [
59].
An interesting fact is that, on the one hand, rare-earths are needed to produce a number of progressive «green» technologies, but, on the other hand, to manufacture REM products innovative mining, refining and processing technologies are needed. Therefore, a growing demand for electric vehicles, wind turbines, and so forth will orderly stimulate a development of novel technologies for REMs’ extraction. Taking into consideration the current market «balance of power», the technologies implemented have to be advanced.
2.2. Conceptual Framework for the Development of the Rare-Earth Metal Industry in the Context of Global Energy Transition Trends
Based on the tendencies, trends and forecasts discussed, the conceptual framework for the development of the rare-earth metal industry in the context of global energy transition has been formed. Clearly, a need for «green» technologies and REMs in the modern economics are linked.
In this study the demand for rare-earth metals is classified as derived demand. This kind of demand for a resource is driven by the demand for the goods that are produced using this resource. Resource demand:
- (A)
Increases in the event of an increase in demand for finished products;
- (B)
Decreases if there is a decrease in demand for finished products created with the help of this type of resources.
Figure 4 reflects the conceptual foundations for the development of the rare-earth metal industry in the context of global energy transition trends.
Based on the presented conceptual framework, the study is based on the following assumptions:
- (1)
Global energy transition trends are associated with the intensification of the use of green technologies (Technology Pillar #1).
- (2)
The level of demand for green technologies will affect the consumption of rare-earth metals and, accordingly, the situation in the rare-earth metal market, where an increase in demand will lead to an increase in prices, especially for heavy group of metals which are more demanded (Market Pillar).
- (3)
Positive changes in the market stimulate the development of technologies for the extraction and processing of rare-earth metals (Technology Pillar #2), thereby acting as a driver pushing the development of the industry that consists of two basic components, which are government regulation and access to raw materials (Resource Pillar).
Technology Pillar #1 and Market Pillar shape demand factors. Technology Pillar #2, Resource Pillar, and government regulation influence REM supply. The cumulative impact of the factors associated with technology and the market will become the framework for transforming the economic foundations for the development of REM initiatives in the context of rising prices and falling costs.
Table 2 provides a more detailed description of the above factors.
Based on the assumptions presented above, we state that the demand for rare-earth metals is elastic in relation to the demand for green technologies. To assess the future demand for rare-earth metals in Russia factoring in the plans for the production of green technologies, it is proposed to use the following formula:
where
De is the demand for REM products caused by the production of a specific green technology;
Ci is the average consumption of a specific rare-earth element in producing the technology under consideration; and
Ve is the volume of production of this type of green technologies. To find the total increase (∆
D) in demand for REMs caused by producing green technologies in a specific period, the following calculation needs to be performed:
In order to determine whether global energy transition trends can act as a driver for the development of the rare-earth metal industry, it is necessary to know whether the country has a plan for fostering production and expanding the use of green technologies that cannot be produced without using REM components. In view of this, it is necessary to answer a number of questions:
- (1)
Does the country have plans for an energy transition?
- (2)
Does it plan to use modern green technologies (construct new production facilities)?
- (3)
How can these trends affect the development of the Russian rare-earth metal industry (taking into account the current state of industrial development)?
In the context of the topic under consideration, it is advisable to turn to specific green technologies that contain rare-earth elements. To forecast future demand for metals caused by growth in the production of environmentally friendly technologies, the previously mentioned scientific article (Zhou et al., 2017) considered such types of technologies as electric vehicles, wind generators, nickel-metal hydride batteries, catalytic converters, and different types of lamps (LED, LFL, CFL) [
11]. As the key objects for this study, we chose two types of technologies that are classified as environmentally friendly and require the largest number of REMs per unit: (a) electric vehicles; (b) wind turbines.
