Material bottlenecks in the future development of green technologies
TL;DR: In this paper, a new methodology is proposed, identifying possible bottlenecks of future demand versus geological availability, which is applied to the world development of wind power, solar photovoltaic, solar thermal power and passenger electric vehicles for the 2016-2050 time period under a business as usual scenario considering the impact on 31 different raw materials.

Global material requirements for the energy transition. An exergy flow analysis of decarbonisation pathways
TL;DR: In this article, the material requirements for 2050 scenarios are assessed in terms of exergy to analyze the impact in natural resources in each scenario and identify which technologies are going to demand more resources.

Assessment of strategic raw materials in the automobile sector
TL;DR: In this paper, a methodology has been developed to identify strategic elements for the automobile sector and a variable called Strategic Metal Index (SMI) which is calculated for each metal is defined, which is the result of combining the following parameters: (1) Automobile sector demand with respect to world production; (2) known resources compared to total cumulative demand and (3) Supply risk.

Vehicles and Critical Raw Materials: A Sustainability Assessment Using Thermodynamic Rarity
TL;DR: In this article, the authors investigate a complementary indicator to material value in passenger vehicles based on exergy, which is called thermodynamic rarity and represents the exergy cost (GJ) needed for producing a given material from bare rock to the market.

Downcycling in automobile recycling process: A thermodynamic assessment
TL;DR: In this article, an assessment of the downcycling degree of minor metals in conventional vehicles using a SEAT Leon III model as a case study was conducted, and the results demonstrated that even if the quantity of downcycled metals only represents 4.5% of the total metal weight of the vehicle, in rarity terms, this figure increases to approximately 27%.
