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 primary objective of the study was to analyze the feasibility of using a large ice water heat sink for power plant cooling and to predict the effect of the relatively cool condenser water, produced by this system, on plant performance. For a chosen hypothetical site, the study has shown that a large ice mass could be produced during winter in northern regions and coupled with a 1000-MW(electric) nuclear power plant to provide year-round cooling water as low as 4.5°C (40°F). When introduced into the plant, this water could increase the thermal efficiency of the particular plant chosen from 34.1 to 35.4%. Although the initial cost of this system is above that of a cooling tower, the additional revenue realized through increased plant efficiency can, over the life of the plant, help to offset this increased cost.
