The U.S. Department of Energy (DOE) has released its Fusion Science and Technology (FS&T) Roadmap, outlining a national strategy to speed up the development and commercialization of fusion energy. The plan aims to deliver commercial fusion power to the grid by the mid-2030s through a Build–Innovate–Grow approach that seeks to align public investment with private sector innovation.
The initiative supports President Trump’s Executive Order Unleashing American Energy, which is intended to expand domestic energy production and strengthen U.S. energy security. The DOE says the Roadmap will help reinforce the nation’s energy grid, rebuild supply chains, and promote 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 presented 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.
More than 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 and to maintain U.S. leadership in the global fusion sector.
The FS&T Roadmap focuses on three main objectives: building critical infrastructure to address materials and technology gaps; fostering innovation through research and advanced computing; and growing the U.S. fusion ecosystem via public-private partnerships, regional manufacturing hubs, 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.”
According to the DOE, over $9 billion in private investment has already gone into burning-plasma demonstrations and prototype reactor designs. The Department is working with national laboratories, industry partners, universities, and international allies to address remaining technical challenges 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 technology, blankets, and plant engineering and integration.
DOE officials note that achieving the milestones outlined in the Roadmap will depend on future public-private partnerships and Congressional appropriations. The Roadmap does not commit the Department to specific funding levels. The full document is available at https://www.energy.gov/fusion-energy.
