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.

A design of a compact fusion reactor is proposed based on the reversed field pinch and utilizing the "Integrated-Blanket-CoiI" (IBC) concept. The IBC is applied to the toroidal field and divertor systems, with liquid metal used for cooling both the first wall and blanket. This simplifies the overall design by requiring only a single coolant cycle. In addition, safety is increased by eliminating any possible lithium-water interaction in the fusion power core. Finally, replacing conventional copper divertor coils with IBC components enhances tritium breeding and energy recovery. A generic problem with liquid metal coolants is their reduced heat transfer capabilities in magnetic fields. In this context, the use of liquid metal coolants may limit the allowable neutron wall loading to a value of 10 MW/m2. Above this value it may be necessary to use water cooling for the first wall and divertor surfaces.
