DOE Releases 2023 Critical Materials Assessment for Clean Energy Tech

The U.S. Department of Energy (DOE) has released its 2023 Critical Materials Assessment (CMA2023) evaluating materials for global clean energy supply chains. Based on the results of the assessment, the DOE has determined a 2023 DOE Critical Materials List of energy-specific critical and near-critical materials through 2035.

The CMA2023 focuses on materials with a high risk of supply disruption that are integral to clean energy technologies. The final list includes many raw materials such as aluminum, cobalt, copper, dysprosium, grain-oriented steel/amorphous steel, fluorine, gallium, iridium, lithium, magnesium, natural graphite, neodymium, nickel, platinum, praseodymium, terbium, silicon, and silicon carbide.

Many of these materials, including rare earth materials (neodymium, dysprosium, etc.) and the materials needed for stationary and electric vehicle power storage, are considered critical and near critical in the short and longer term.
