Energy Department Releases Finalized Fusion Science and Technology Roadmap to Accelerate Commercial Fusion Power

WASHINGTON-The U.S. Department of Energy (DOE) today released the finalized Fusion Science and Technology (FS&T) Roadmap, a national strategy to accelerate the development and commercialization of fusion energy on the most rapid, responsible timeline in history. Building on earlier roadmap efforts, the finalized roadmap brings together fusion science, technology, infrastructure, workforce development, and commercialization priorities into a single national strategy to support fusion pilot plants and commercial fusion power in the mid-2030s.

Fusion is the process that powers the sun and stars. For decades, scientists and engineers have worked to bring that same process to Earth as a source of abundant, reliable energy. The finalized roadmap outlines how DOE, industry, universities, and national laboratories will work together to accelerate the path toward commercial fusion energy in the United States.

This effort advances President Trump's energy dominance agenda and reinforces the Administration's commitment to expanding reliable American energy production, strengthening domestic supply chains, and maintaining U.S. leadership in critical technologies. By accelerating progress toward commercial fusion power, DOE is helping secure a future of abundant and reliable energy.

"Fusion energy has entered a new era defined by extraordinary scientific progress and public-private momentum," said DOE Under Secretary for Science Dr. 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."

Developed with input from more than 800 scientists and engineers across the public and private sectors, the finalized FS&T Roadmap reflects contributions from more than 15 private companies, over 10 National Laboratories, and more than 70 universities. The roadmap identifies the critical science and technology gaps that must be closed to realize fusion pilot plants and strengthen U.S. leadership in the global fusion industry.

The FS&T Roadmap establishes a unified strategy for the U.S. fusion enterprise built around three primary drivers:

• Build critical infrastructure to close fusion materials and technology gaps.
• Innovate through advanced research, high-performance computing, and artificial intelligence.
• Grow the U.S. fusion ecosystem through public-private partnerships, supply chain development, workforce growth, and commercialization pathways.

The roadmap aligns with DOE's Genesis Mission and will be implemented through the DOE's newly established Office of Fusion, leveraging artificial intelligence, advanced computing, and public-private collaboration to accelerate fusion research, engineering, and commercialization. With more than $10 billion in private investment already advancing fusion technologies and demonstration projects, DOE is coordinating a national effort to close the remaining technical gaps needed to commercialize fusion energy. Through the Build-Innovate-Grow strategy, DOE and its partners are strengthening domestic supply chains, advancing fusion science, and positioning the United States to lead the global race to commercialize fusion energy.

The activities outlined in the Fusion Science and Technology Roadmap are focused on prioritizing strategic directions for DOE to further collaborate with the U.S. fusion industry. DOE's ability to support the roadmap's milestones and timelines is contingent on future public-private partnerships and future Congressional appropriations. This roadmap is not committing DOE to specific funding levels.
