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 erosion of carbon deposition layers by oxygen exposure and the desorpstion of hydrogen retained in the layers were investigated experimentally. Carbon deposition layers were formed by a sputtering method using hydrogen RF plasma. The layers were exposed to an argon gas with oxygen of 1013 Pa in the temperature range of 200-400°C. The erosion reaction progressed quickly within 10 minutes and then decelerated rapidly. The measurement of the outlet concentration revealed that most of the layer was eroded not as carbon monoxide and carbon dioxide but as soot. Additionally, it was estimated that the soot was released from the carbon deposition layer with a large amount of hydrogen.
