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.

The properties of a classical stellarator will be described and the need to optimise stellarators will be motivated. The principles of optimisation will be presented. W7-AS, a partly optimised modular stellarator, will be briefly introduced and some results with relevance to its optimised properties will be summarised. The fully optimised large stellarator W7-X will be described and the progress in optimisation from W7-AS to W7-X will be discussed. The possible design of an optimised stellarator reactor will be presented.
