The Critical Materials Future Act of 2025 establishes a pilot program run by the Department of Energy to support domestic processing of critical materials needed for energy, technology, and defense applications. The program will provide financial support to at least three domestic critical material processing projects, using innovative financial tools such as price guarantees and contracts to make these projects economically competitive and attract private investment. The bill aims to reduce U.S. dependence on foreign suppliers, particularly from countries viewed as strategic risks, by building a more stable domestic supply chain for materials like rare earths and other minerals essential to modern infrastructure. The program will operate for up to five years, with the Secretary required to select projects within one year of enactment and submit annual reports to Congress on progress and recommendations. The bill authorizes $750 million in funding and establishes a revolving fund to reinvest revenues from supported projects into new processing ventures.
