The Fusion Science & Technology (S&T) Roadmap is a comprehensive national strategy to accelerate the development and commercialization of fusion energy by the mid-2030s.
It charts a clear path for federal support to the growing fusion energy industry, identifying critical science and technology gaps and defining the milestones needed to bring commercial fusion power to the grid. Developed with broad input from over 600 researchers, engineers, and industry stakeholders, the roadmap establishes DOE’s Build–Innovate–Grow strategy for advancing a robust and competitive U.S. fusion sector.
This effort advances President Trump’s Executive Order Unleashing American Energy, reinforcing the Administration’s commitment to expand domestic energy production and restore U.S. energy dominance. By accelerating progress toward commercial fusion power, DOE is strengthening America’s grid, rebuilding critical supply chains, and securing a new era of abundant, reliable, American-made energy.
The goal of the Fusion S&T Roadmap is to deliver the public infrastructure that supports the fusion private sector scale up in the 2030s.
The activities outlined in the Fusion S&T Roadmap are focused on prioritizing strategic directions for the DOE to further collaborate with the US Fusion Industry. DOE’s ability to support this Roadmap’s milestones and timelines of scaling up the domestic fusion private sector by the 2030s is contingent on the development of future public private partnerships. This Roadmap is not committing DOE to specific funding levels, and future funding will be subject to Congressional appropriations.
