The Advanced Materials & Manufacturing Technologies Office's (AMMTO) Critical Minerals and Materials portfolio addresses high-impact opportunities and challenges across the entire life cycle of high priority critical minerals and materials for energy technologies. The United States lacks a strong domestic supply of many minerals and materials which will be critical to a decarbonized energy infrastructure as well as current manufacturing technologies. These include:

  • Rare earth elements, used in offshore wind turbine generators and electric vehicle motors;
  • Lithium, cobalt, and high-purity nickel, used in energy storage technologies;
  • Platinum group metals used in catalysts for automotive, chemical, fuel cell, and green hydrogen products; and
  • Gallium and germanium used in semiconductors.

The DOE critical minerals & materials strategy is based on the following pillars:

  • Diversifying supplies of critical minerals and materials;
  • Developing alternatives to critical minerals and materials;
  • Improving materials and manufacturing efficiency;
  • Investing in circular-economy approaches; and
  • Enabling activities such as criticality assessments.
