Critical Minerals & Materials Accelerator (CMMA)

Critical Minerals and Materials Accelerator (CMMA) is AMMTO's FY2026 competitive FOA under the U.S. Department of Energy. It spans three topic areas: production and material efficiency for critical minerals, refining processes for semiconductor-critical materials such as gallium, germanium, and silicon carbide, and cost-competitive direct lithium extraction, separation, and processing technologies. The program is aimed at domestic supply chain resilience and advanced materials processing. Applications move through DOE's EERE Exchange portal, with Grants.gov cross-posting, and each topic carries its own letter-of-intent and full-application deadline in spring and summer 2026. The opportunity is U.S.-based, with eligibility for for-profit firms, nonprofits, universities, and research organizations, while individuals are excluded. The strongest proposals are tightly matched to one topic and built around a process or materials problem that can be evaluated on its own terms. Because the topics do not move on a single shared deadline, applicants need to choose the right lane early and avoid trying to stretch one concept across all three.

Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.
