The U.S. Department of Energy (DOE) has released its Fusion Science and Technology (FS&T) Roadmap, outlining a national strategy aimed at accelerating the development and commercialization of fusion energy. The plan seeks to deliver commercial fusion power to the electric grid by the mid-2030s, aligning public investment with private sector innovation.
This initiative supports President Trump’s Executive Order on Unleashing American Energy, which emphasizes expanding domestic energy production and enhancing U.S. energy independence. According to the DOE, advancing fusion energy will strengthen the nation’s electric grid, rebuild supply chains, and contribute to a more reliable energy future.
Energy Department Under Secretary for Science Dr. Darío Gil stated, “The Fusion Science and Technology Roadmap brings unprecedented coordination across America’s fusion enterprise. 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 FS&T Roadmap was introduced during a series of U.S. Fusion Energy Enterprise Events in Washington, D.C., where government, industry, and academic leaders gathered to discuss the future of American fusion energy. The roadmap was developed with input from over 600 scientists, engineers, and stakeholders from various sectors. It identifies key areas—such as research, materials development, and technology gaps—that must be addressed to achieve a Fusion Pilot Plant and maintain U.S. leadership in the global fusion sector.
The strategy centers on three main objectives: building critical infrastructure to address materials and technology gaps; fostering innovation through research and advanced computing; and expanding the U.S. fusion ecosystem via public-private partnerships and workforce development initiatives.
Jean Paul Allain, Associate Director of DOE’s Office of Fusion Energy Sciences, said, “Fusion is real, near, and ready for coordinated action. 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 directed toward fusion research and prototype reactors, the DOE aims to coordinate efforts to resolve remaining technical challenges in areas such as materials science, plasma systems, fuel cycles, and plant engineering. The roadmap details plans for investment in six core areas: structural materials, plasma-facing components, confinement systems, fuel cycle, blankets, and plant engineering and integration.
The DOE’s roadmap emphasizes collaboration with the U.S. fusion industry and highlights that achieving its milestones depends on future public-private partnerships and Congressional funding decisions. The roadmap does not set specific funding levels at this time.
