U.S. DOE Releases Fusion Science and Technology Roadmap

The U.S. Department of Energy has published its Fusion Science and Technology Roadmap, a national strategy aimed at accelerating the commercialization of fusion energy by the mid-2030s. Organized around a Build–Innovate–Grow framework, the Roadmap sets near-term (2–3 years), mid-term (3–5 years), and long-term (5–10 years) actions to close critical gaps in materials, fuel cycle, plasma-facing components, confinement, blankets, and plant engineering — the six Core Challenge Areas identified as standing between today's private-sector demonstration platforms and a viable Fusion Pilot Plant in the 2030s.

The document also outlines a planned AI-Fusion Digital Convergence Platform intended to accelerate design and modeling across the field, and maps its priorities to the 2020 FESAC Long-Range Plan and DOE's newly formed Office of Fusion.

As DOE Under Secretary for Science Darío Gil frames it, the Roadmap is meant to chart a clear path for federal support to the fusion industry, identifying the science and technology milestones needed to bring commercial fusion power to the grid.
