Critical Minerals and Materials Accelerator Notice of Funding Opportunity

This Notice of Funding Opportunity (NOFO) supports critical minerals and materials. Critical minerals and materials (CMM) are the building blocks for technologies foundational to U.S. energy dominance, national security, and industrial competitiveness. To build a secure domestic supply of CMMs, the U.S. Department of Energy (DOE) aims to support collaborative industry partnerships to prototype and pilot innovative processing technologies that are currently only proven at the bench scale to address CMM challenges in high impact areas. The CMM Accelerator program will advance these mid-stage innovations through validation, benchmarking, access to national lab test beds, testing in industry relevant environments, technoeconomic analysis, and life-cycle assessment. The program establishes a pipeline to support technology maturation to ultimately unlock private capital investments. It also will leverage other DOE lab-based activities, such as the Critical Materials Innovation Hub (CMI Hub) and the Minerals to Materials Supply Chain Research Facility (METALLIC).
