U.S. Energy Department Launches National Strategy to Speed Fusion Power Deployment by Mid-2030s

The U.S. Energy Department on Oct. 16 released its Fusion Science and Technology Roadmap, outlining a national strategy to speed up the transition of fusion energy from research to commercial deployment within the next decade. The plan defines DOE’s Build–Innovate–Grow framework to align public funding with private sector innovation to deliver fusion-generated electricity to the grid by the mid-2030s.

The initiative supports the administration’s broader goal of expanding domestic energy supply and reinforcing the nation’s energy independence. By expediting progress in fusion development, the department aims to improve grid reliability, rebuild manufacturing networks, and establish U.S. leadership in emerging clean energy technologies.

Prepared with input from more than 600 scientists, engineers, and industry partners, the roadmap identifies the research and technology priorities needed to construct a demonstration-scale fusion pilot facility and strengthen the nation’s position in the growing global fusion market. It emphasizes three main objectives: expanding essential infrastructure, driving innovation through advanced computing and artificial intelligence, and building a robust fusion industry through partnerships, regional production hubs, and workforce initiatives.

With over $9 billion in private investment already supporting prototype reactors and plasma demonstration projects, the plan sets a unified approach to bridge remaining technical gaps across six areas including structural materials, plasma-facing components, confinement systems, fuel cycles, blankets, and overall plant integration. The initiative will coordinate efforts among national laboratories, universities, private developers, and international partners to enhance domestic capabilities and supply chains.

While the roadmap provides a comprehensive strategic direction, it does not commit the department to specific funding levels. Future financial support will depend on congressional appropriations and the creation of new public-private partnerships. The approach aims to secure U.S. leadership in the global race toward commercial fusion energy while driving economic growth and advancing a clean, reliable energy future.

Last month, the department announced $134 million in funding to advance fusion energy research through initiatives. The Fusion Innovative Research Engine collaboratives will receive $128 million to support seven teams creating a national innovation ecosystem that bridges basic science and industry applications. An additional $6.1 million will fund 20 projects under the Innovation Network for Fusion Energy, aimed at accelerating private-sector development through partnerships with national laboratories and universities.
