The Department of Energy unveiled the finalized version of its Fusion Science and Technology Roadmap on Tuesday.
The Fusion Science and Technology Roadmap serves as a national strategy to expedite the development and commercialization of fusion energy on a fast track. The newest fusion strategy aligns DOE and private industry to bring together fusion energy, infrastructure and commercialization priorities into a national strategy to support fusion pilot plants and commercial fusion power in the mid 2030s.
DOE said this roadmap builds off of similar efforts that were released in October 2025. DOE said in a press release that the roadmap aligns with its Genesis Mission and will be implemented through its recently established Office of Fusion.
DOE said in the roadmap that the pathway “provides a potential future set of foundational infrastructure for a rapidly scaling, successful, world-leading U.S. fusion energy industry of the 2030s and 2040s.”
Additionally, the roadmap outlines the DOE pathway to provide fusion science and technology infrastructure and the artificial intelligence (AI)-fusion digital convergence platform along the same near-, mid- and long-term schedule that would support development of a fusion pilot plant in the 2030s, according to the document. DOE said that progress is being enabled and accelerated by combining fusion and AI research.
According to DOE, the roadmap forms a unified strategy for the domestic fusion industry built around three main points:
- Build critical infrastructure to close fusion materials and technology gaps.
- Innovate through advanced research, computing and artificial intelligence.
- Increase the domestic fusion complex through public-private partnerships, supply chain development, workforce and commercialization pathways.
DOE’s ability to support the roadmap’s milestones and timelines is contingent on future public-private partnerships and future Congressional appropriations, according to the release. The roadmap will not commit DOE to specific funding levels.
“Fusion energy has entered a new era defined by extraordinary scientific progress and public-private momentum,” said DOE Under Secretary for Science Darío Gil. “With this roadmap, we now have the clarity, coordination, and sustained commitment needed to turn the promise of fusion into a reality for the American people.”
