U.S. DOE Fusion Science and Technology Roadmap (Finalized, June 2026)

The U.S. Department of Energy (DOE) "Fusion Science and Technology Roadmap" (published June 2026, 122 pages) establishes a comprehensive national strategy to accelerate the commercialization of fusion energy and support a scaling private fusion industry targeting pilot plants by the mid-2030s. Aligned with the 2020 FESAC Long-Range Plan and the newly established Office of Fusion (OF), the Roadmap is organized around the "Build-Innovate-Grow" strategic framework. It defines phased actions across near-term (2–3 years), mid-term (3–5 years), and long-term (5–10 years) horizons across six core Challenge Areas: Structural Materials, Plasma-Facing Components/Plasma-Material Interactions, Confinement Approaches, Fuel Cycle/Tritium Processing, Blanket S&T, and Plant Engineering/System Integration. The roadmap prioritizes closing Fusion Materials & Technology (FM&T) gaps, establishing public-private testbeds, and advancing AI-fusion digital convergence via the Genesis Mission.
