The Department of Energy introduced a Fusion Science & Technology (S&T) Roadmap on October 16 as a national “Build–Innovate–Grow” strategy to develop and commercialize fusion energy by the mid-2030s by aligning public investment and private innovation. Hailed by Darío Gil, the DOE’s new undersecretary for science, as bringing “unprecedented coordination across America's fusion enterprise” and advancing President Trump’s January 2025 executive order, “Unleashing American Energy,” the road map echoes plans issued by the DOE’s Office of Fusion Energy Sciences (FES) in 2023 and 2024, with a new emphasis on the convergence of AI and fusion.

The road map release coincided with other fusion energy events held this week in Washington, D.C., and beyond.

The Office of Fusion Energy Sciences (FES) in the Department of Energy’s Office of Science introduced a new plan—"Building Bridges: A Vision for the Office of Fusion Energy Sciences”—during a Fusion Energy Sciences Advisory Committee (FESAC) hearing on December 13, and announced that news December 14. What’s included? A plan for the DOE to “establish the steps needed to help advance fusion energy, including addressing key science and technology gaps in the supply chain and industry.” The vision is less a guiding document than a preview of DOE-FES’s near-term intentions, which include drafting a fusion science and technology road map in 2024 to shape investments for the coming decade.

The Department of Energy’s Office of Science published a notice in the March 27 Federal Register calling for input on technological approaches to a Fusion Prototypic Neutron Source (FPNS) for materials irradiation research under DOE-SC’s Fusion Energy Sciences program, as well as partnership models that could accelerate the construction and delivery of the facility. The request for information (RFI) calls for responses by May 11.

The Department of Energy announced up to $50 million for a new milestone-based fusion energy development program on September 22. The funding opportunity announcement is open to for-profit companies—possibly teamed with national laboratories, universities, and others—that are prepared to meet major technical and commercialization milestones leading to a pilot fusion power plant design.

• ARDP picks divergent technologies in Natrium, Xe-100: Is nuclear’s future taking shape? The Department of Energy has put two reactor designs—TerraPower’s Natrium and X-energy’s Xe-100—on a fast track to commercialization, each with an initial $80 million in 50-50 cost-shared funds awarded through the Advanced Reactor Demonstration Program.

The Energy Sciences Coalition (ESC) issued a letter today to the incoming Biden administration’s transition team for the Department of Energy. The ESC is a broad-based group of organizations representing scientists, engineers, and mathematicians from universities, industry, and national laboratories that is committed to supporting and advancing the scientific research programs of the DOE and, in particular, the DOE Office of Science.

The Fusion Energy Science Advisory Committee (FESAC), which is responsible for advising the Department of Energy’s Office of Science, on December 4 published the first public draft of Powering the Future: Fusion and Plasmas, a 10-year vision for fusion energy and plasma science. FESAC was charged with developing a long-range plan in November 2018.

The scope: The report, which is meant to catch the eye of leaders in the DOE, Congress, and the White House, details the needs of the fusion and plasma program identified by a FESAC subcommittee—the DOE Fusion Energy Sciences Advisory Committee for Long Range Planning—with the help of the fusion research community. The yearlong Phase 1 of the Community Planning Process, organized under the auspices of the American Physical Society’s Division of Plasma Physics, gathered input and yielded a strategic plan that is reflected in the FESAC’s draft report.
