U.S. Department of Energy's 2023 Critical Materials Assessment: A Comprehensive Review of Clean Energy Supply Chains

The U.S. Department of Energy (DOE) has recently unveiled its highly anticipated 2023 Critical Materials Assessment (2023 CMA), marking a significant milestone in the evaluation of materials critical to global clean energy technology supply chains. This assessment, which plays a crucial role in shaping the future of clean energy technologies, will have a profound impact on DOE priorities and tax credits. In this article, we will provide an in-depth analysis of the key findings from the 2023 CMA, as well as the implications for the clean energy industry.

The Importance of the 2023 Critical Materials Assessment

The 2023 DOE Critical Materials Assessment is a comprehensive evaluation that identifies energy-specific critical and near-critical materials that will be crucial for the clean energy industry through 2035. The assessment takes into account the importance of these materials in clean energy technologies and their susceptibility to potential supply disruptions. By determining the criticality of these materials, the DOE aims to prioritize research and development efforts and reduce reliance on materials with high supply risks.

Key Materials Identified in the 2023 Critical Materials Assessment

The 2023 DOE Critical Materials List includes a wide range of materials that are deemed critical or near critical for the clean energy industry. These materials have been selected based on their significance in clean energy technologies and their potential vulnerability to supply disruptions. Let's delve into the key materials identified in the assessment and their implications for the industry.

Rare Earth Materials: Neodymium, Praseodymium, Dysprosium, and Terbium

Rare earth materials, including neodymium (Nd), praseodymium (Pr), dysprosium (Dy), and terbium (Tb), have been identified as critical materials in the 2023 CMA. These materials play a vital role in the production of magnets used in electric vehicle (EV) motors and wind turbine generators. While dysprosium and terbium serve similar functions, terbium's criticality is slightly lower due to its role as a substitute for dysprosium in high-grade magnets. Similarly, praseodymium is considered near-critical in the short term because it can be more easily substituted in magnets compared to neodymium.

Materials for EV and Stationary Storage Batteries: Cobalt, Lithium, and Natural Graphite

The assessment recognizes the criticality of materials used in batteries for EVs and stationary storage. Cobalt (Co), which has been recognized as critical in previous reports, continues to be essential due to its widespread use in battery chemistries. However, the rapid growth of the EV industry has also led to the inclusion of lithium (Li) as a critical material. The versatile use of lithium in various battery chemistries, coupled with the increasing demand for EVs, underscores its significance. Furthermore, natural graphite has been newly added to the critical materials list, highlighting its importance in battery technologies.

Platinum Group Metals: Platinum, Iridium, Rhodium, and Palladium

Platinum group metals (PGMs) play a crucial role in clean energy technologies. Platinum (Pt) and iridium (Ir) are identified as critical materials due to their importance in hydrogen electrolyzers, which are essential for achieving net-zero carbon emissions. However, PGMs used in catalytic converters, such as rhodium (Rh) and palladium (Pd), are considered less critical in the medium term due to the decreased importance of catalytic converters.

Gallium: Critical for LEDs and Semiconductors

Gallium (Ga) is another critical material identified in the 2023 CMA. Its applications in light-emitting diodes (LEDs) and its expanding use in magnet manufacturing and semiconductors, particularly in the forms of gallium arsenide (GaAs) or gallium nitride (GaN), underline its criticality in the clean energy industry.

Aluminum, Copper, Nickel, and Silicon: Increasing Importance in Electrification

Major materials such as aluminum (Al), copper (Cu), nickel (Ni), and silicon (Si) are projected to move from noncritical in the short term to near critical in the medium term. This shift reflects their increasing importance in the process of electrification. The inclusion of copper as a critical material by a U.S. federal agency for the first time aligns with global characterizations of copper's criticality, recognizing its significance in clean energy technologies.

Electrical Steel: Crucial for Grid Transformers and EV Motors

Electrical steel, used in transformers for the grid and electric motors in EVs, is classified as near critical due to its significance in these crucial components. This recognition highlights the importance of maintaining a stable supply of electrical steel to support the clean energy transition.

Implications for the Clean Energy Industry

The 2023 Critical Materials Assessment has significant implications for the clean energy industry. The identification of critical and near-critical materials provides valuable insights for policymakers, researchers, and industry stakeholders to prioritize research and development efforts and reduce supply chain risks. By addressing material-specific risks and ensuring a stable supply of critical materials, the industry can accelerate the transition to clean energy technologies and achieve sustainability goals.

Conclusion

The U.S. Department of Energy's 2023 Critical Materials Assessment serves as a comprehensive evaluation of materials critical to global clean energy technology supply chains. Through the identification of critical and near-critical materials, the assessment enables the prioritization of research and development efforts and the mitigation of supply chain risks. The inclusion of materials such as rare earths, lithium, and gallium underscores their importance in clean energy technologies. As the clean energy industry continues to evolve, the findings from the 2023 CMA will play a pivotal role in shaping policies and strategies to drive the transition towards a sustainable and resilient energy future.
