The U.S. House Committee on Science, Space, and Technology convened on September 19, 2025, to discuss the critical advancements and future potential of fusion power, emphasizing the urgency for increased investment and collaboration in this transformative energy sector.

Key discussions highlighted the significant progress made in fusion research, particularly through the National Ignition Facility and international collaborations like ITER. U.S. scientists have achieved record results, showcasing the potential of fusion energy to reshape the energy landscape. However, experts warned that without robust public-private partnerships, the U.S. risks losing its leadership in fusion technology to countries like China, which has significantly outpaced American investment in recent years.

Dr. Mumbgaard, CEO of Commonwealth Fusion Systems, underscored the urgency of the moment, stating, "A working fusion power plant is not a matter of if, it's a matter of when and where." He noted a surge in private investment, with the number of fusion companies in the U.S. rising from 23 to 53 and total funding increasing from $2 billion to $10 billion in just a few years. This momentum, however, is threatened by a lack of coordinated government support and investment.

The committee members echoed these concerns, with calls for a one-time $10 billion investment in fusion research and demonstration to ensure the U.S. remains competitive. This funding would support existing commercialization programs and the development of necessary infrastructure, such as new facilities for testing and materials research.

As the meeting concluded, the message was clear: decisive action is needed now to turn the promise of fusion power into a commercial reality. The U.S. must act swiftly to foster innovation and collaboration, or risk falling behind in the global race for sustainable energy solutions.
