Recent congressional testimony has highlighted growing concerns over China’s rapid advancement in fusion energy technology, with experts warning that Beijing could achieve commercial fusion power generation by 2030. Since 2023, China has invested approximately $13 billion in fusion development, positioning itself to potentially become the first nation to harness this revolutionary energy source.
During a House Science, Space, and Technology Committee’s Energy Subcommittee hearing on September 18, industry leaders and scientists urged the United States to accelerate its fusion energy initiatives to maintain competitiveness. Energy Subcommittee Chair Rep. Randy Weber (R-Texas) emphasized the importance of ensuring fusion technology development remains in the hands of democratic nations rather than authoritarian regimes that might weaponize energy dominance.
Fusion energy, which replicates the power generation process of stars by combining atoms, represents a potential source of unlimited, clean energy. The field has seen significant progress since 2022, when Lawrence Livermore National Laboratory achieved a breakthrough by producing more energy from a fusion reaction than was required to power it.
Commonwealth Fusion Systems CEO Bob Mumgaard, testifying before the subcommittee, likened recent advances to aviation’s “Kitty Hawk moment” and called for a one-time $10 billion Department of Energy funding boost. The U.S. fusion industry has experienced substantial growth, expanding from 23 companies with $1.78 billion in private capital in 2021 to 53 companies with $10.6 billion in 2024.
Oak Ridge National Laboratory Fusion Energy Division Director Troy Carter supported Mumgaard’s funding proposal, stressing the critical timing for American leadership in commercializing fusion energy. Pacific Fusion founder Will Regan emphasized America’s historical success in converting scientific breakthroughs into industrial applications through private sector partnerships.
The Trump administration’s fiscal year 2026 budget proposal has garnered bipartisan support for its fusion initiatives, with Rep. Zoe Lofgren (D-Calif.) expressing approval of the direction despite overall opposition to the budget. The Department of Energy’s budget request includes $7.1 billion for the Office of Science, specifically emphasizing maintaining U.S. competitiveness in fusion research.
Industry experts outlined recommendations for maintaining U.S. leadership, including establishing fusion demonstration programs similar to DOE’s advanced fission reactor program. These programs would aim to accelerate the deployment of multiple fusion power plant approaches, with construction beginning by 2028 and operations starting in the early 2030s.
University of Wisconsin assistant professor Stephanie Diem highlighted fusion energy’s potential to address growing global energy demands while mitigating geopolitical tensions related to energy resource access. The experts advocated for a milestone-based funding approach that would reward substantial progress and require clear paths to commercial success.
The hearing underscored the strategic importance of fusion energy development in maintaining technological leadership and energy independence. With China’s aggressive investment and development timeline, the United States faces pressure to enhance its fusion research and development efforts through increased funding,
international cooperation with allies, and accelerated demonstration programs. The race to commercialize fusion energy has significant implications for future global energy dynamics and international relations, making it a critical focus for U.S. technological and economic strategy.
