Continuation of Solicitation for the Office of Science Financial Assistance Program

The FY2026 Continuation Solicitation sits under DOE Fusion Energy Sciences inside the Office of Science financial assistance portfolio. It is the department's annual open-window route for research across the Office of Science, with FES topics called out for AI and machine learning for fusion, high-energy-density physics, and public-private partnership work. The instrument is a grant, the geography is the United States, and the call runs from September 30, 2025 through September 30, 2026. The record allows for-profit companies, nonprofits, universities, and research organizations, while excluding individuals. Pre-applications are optional but encouraged, and some review panels may require them, which makes the route suitable for teams that can respond quickly to a continuing federal solicitation. The program is best suited to groups already working in fusion research or adjacent enabling areas rather than applicants looking for a one-time demonstration award. It rewards proposals that fit the stated topic areas cleanly, follow the solicitation timetable, and arrive with a clear technical case. In practice, that favors groups with strong research credentials, a defined collaboration structure, and a project that can be evaluated against the Office of Science's standard review process.

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