The American Leadership in Fusion Act establishes a comprehensive federal program to accelerate fusion energy development and build a skilled workforce in this emerging industry. The bill creates a new Department of Energy Office of Fusion headed by an Assistant Secretary to coordinate research, development, and commercialization efforts, with a goal of beginning construction on multiple private fusion pilot plants by the end of 2028. It authorizes approximately $3 billion for a demonstration program supporting private companies in building fusion facilities capable of generating at least 50 megawatts of electricity to the grid, along with $800 million for materials research through 2027 and $100 million for supply chain development. The legislation also directs the National Science Foundation and Department of Energy to invest $45 million annually through 2031 in education and workforce programs, including grants to colleges, universities, and labor organizations to develop fusion-related curricula, internships, and apprenticeships with special focus on underrepresented communities. Overall, the bill authorizes between $1.1 billion and $1.3 billion annually through 2031 to position the United States as a global leader in commercial fusion technology.
