The U.S. Department of Energy (DOE) has released its Fusion Science and Technology (FS&T) Roadmap, which aims to speed up the development and commercialization of fusion energy. The roadmap outlines the Build–Innovate–Grow strategy, designed to coordinate public and private efforts to deliver commercial fusion power to the grid by the mid-2030s.
This initiative is part of the Administration’s broader goal to increase domestic energy production and reinforce U.S. energy independence. The DOE’s approach seeks to strengthen the national power grid, rebuild supply chains, and support the growth of American-made energy.
“The Fusion Science and Technology Roadmap brings unprecedented coordination across America’s fusion enterprise,” said Energy Department Under Secretary for Science Dr. Darío Gil. “For the first time, DOE, industry, and our National Labs will be aligned with a shared purpose—to accelerate the path to commercial fusion power and strengthen America’s leadership in energy innovation. Thanks to President Trump’s leadership, the Department is streamlining the full strength of the U.S. scientific and industrial base to deliver fusion energy faster than ever before.”
The roadmap was introduced during a series of U.S. Fusion Energy Enterprise Events in Washington, D.C., which gathered representatives from government, industry, and academia to discuss the future of fusion energy in the United States.
Input from over 600 scientists, engineers, and industry stakeholders contributed to the development of the roadmap. It identifies key research and technology gaps that need to be addressed to achieve a Fusion Pilot Plant (FPP) and maintain U.S. leadership in the global fusion sector.
The strategy is organized around three main objectives: building critical infrastructure to address technology gaps, innovating through advanced research and technology, and growing the fusion ecosystem through partnerships and workforce development.
“Fusion is real, near, and ready for coordinated action,” said Jean Paul Allain, Associate Director of DOE’s Office of Fusion Energy Sciences. “This roadmap provides the strategic foundation for building the scientific, technical, and industrial base needed to ensure American leadership in commercial fusion on an ambitious timeline.”
With over $9 billion in private investment already supporting demonstration projects and prototype reactors, DOE is working to close remaining technical gaps in areas such as materials, plasma systems, fuel cycles, and plant engineering. The roadmap details plans for investments in six core areas: structural materials, plasma-facing components, confinement systems, fuel cycle, blankets, and plant engineering and integration.
The roadmap’s activities are intended to guide DOE’s collaboration with the U.S. fusion industry. Achieving its milestones will depend on developing public-private partnerships and securing funding through Congressional appropriations. The roadmap does not commit DOE to specific funding levels.
