INFUSE — Innovation Network for Fusion Energy

INFUSE is DOE Fusion Energy Sciences' partnership program for U.S. private fusion companies that need access to national laboratory or university expertise. Oak Ridge National Laboratory and Princeton Plasma Physics Laboratory jointly run the program on DOE's behalf, and the work is designed to move private fusion technologies toward realization. Most awards are one-year projects in the $100,000 to $500,000 range, and companies must provide a 20% cost share. Funding is delivered to the partner institution rather than directly to the company, so each project has both a company PI and a lab or university PI. The topic areas include enabling technologies, materials science, diagnostics, modeling and simulation, unique experimental capabilities, and commercialization paths. The structure favors companies that already know what expertise they need and can work in a lab-linked partnership. A single company may submit up to five requests in a cycle, and the FY2026 process was active in the source window after FY2025 reached $6.1 million across 20 projects.

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