DOE Fusion Energy Sciences (FES)
Supports United States. fusion research through DOE Energy Sciences partnerships across labs and industry.
DOE Fusion Energy Sciences is the Department of Energy Office of Science program that funds the scientific foundation for a U.S. fusion energy industry. Its roadmap organizes work around theory and simulation, fusion materials, sustaining a burning plasma, and closing the fusion cycle. The program's funding range runs from $500,000 to $50,000,000, with a median actual award of $5,000,000, annual cadence, and U.S.-based applicants at TRL 3-9. The 2026 opportunities page lists the Genesis Mission, the FY 2026 Continuation of Solicitation, and the Early Career Research Program, with additional public-private partnership work such as volumetric neutron sources. FES is strongest for teams that can combine fusion science with a path to facilities, materials, or advanced diagnostics. It funds work across public and private sectors, so the best applicants are U.S.-based companies, universities, or research organizations that can meet DOE submission requirements and turn technical progress into a credible fusion platform.
