Critical Minerals and Materials Accelerator | Department of Energy Critical Minerals and Materials Accelerator Light Text on a Dark Overlay (Default) Notice of Funding Opportunity: Critical Minerals and Materials Accelerator Funding amount: Up to $69,000,000 On April 7, 2026, the Office of Critical Minerals and Energy Innovation (CMEI) Advanced Materials and Manufacturing Technologies Office (AMMTO), in partnership with the Office of Geothermal, announced a “Critical Minerals and Materials Accelerator” Notice of Funding Opportunity (NOFO) of up to $69 million.
The NOFO will focus investments on American, industry-led partnerships to prototype and pilot innovative critical materials processing technologies that are currently only proven at the bench scale to address challenges in high-impact areas. The program establishes a pipeline that will support technology maturation to ultimately unlock private capital investments.
It will also leverage other DOE lab-based investments, such as the Critical Materials Innovation (CMI) Hub and the Minerals to Materials Supply Chain Research Facility (METALLIC). This NOFO will help ensure a more secure, predictable, and affordable supply of critical minerals and materials that are foundational to American energy dominance, national security, and industrial competitiveness.
The NOFO includes the following topic areas: Topic Area 1 : Production and material efficiency for critical materials, including rare earth elements (REEs).
Inclusive of the following sub-topics: 1A: Recovery and production from postindustrial manufacturing scrap 1B: Recovery and production from postconsumer scrap (with an emphasis on electronic waste and drivetrains) 1C: Recovery and production from blended feedstocks including mine tailings, postindustrial scrap, and postconsumer scrap Topic Area 2 : Processes to refine and alloy gallium, gallium nitride, germanium, and silicon carbide.
Topic Area 3 : Cost-competitive direct lithium extraction, separation, and processing.
Inclusive of the following sub-topics: 3A: Cost-competitive direct lithium extraction 3B: Advancing pre- and post- treatment and disposal technologies for direct lithium extraction 3C: Exploration and characterization of critical materials and REEs from volcanic-hosted geothermal systems This NOFO is one of several totaling nearly $1 billion that will advance and scale mining, processing, and manufacturing technologies across key stages of the critical minerals and materials supply chains.
