The Commerce Department released on Tuesday an interagency report that identifies a list of minerals deemed critical to U.S. strategic interests and outlines an action plan to ensure their supply.

Why it matters: Securing these minerals and their supply chains is essential to leading the way on technologies that will enable the global energy transition, including cobalt and lithium for batteries, graphite and scandium for fuel cells, and indium and tellurium for solar panels.
