DOE’s latest fusion energy road map aims to bridge known gaps
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, on “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.

Conceptual design study of 14-MeV neutron source (FEF) of compact DT plasma based on the mirror confinement has been carried out to clarify the critical issues both in plasma physics and engineering. Characteristic feature of FEF-II are (i) use of RF pondermotive force for MHD stability, (ii) use of water for radiation shield of SC coil and (iii) use of end electrode system including plasma direct energy conversion. Several sets of plasma parameters are obtained under the variety of conditions from the most pessimistic case where the charge exchange (CX) loss of ions is dominant to the most optimistic case where the CX loss is negligible. The engineering feasibility has been studied for the pessimistic case. It was found that most of the engineering are feasible in the optimistic case, and that even in the pessimistic case by increasing plasma parameters there is possibility to meet engineering requirement.
