Today, Peak Nano took the floor in the Rayburn House Office Building to testify before the House Fusion Caucus in support of : the Fusion Advanced Manufacturing Parity Act.
Our message was simple. will be built, supplying up to 20% of U.S. power generation. That will require roughly 1,500 plants, each consuming 2 to 5 million pounds of capacitor film per year.
Behind every fusion machine are millions of high‑voltage capacitors, firing billions of times over decades. Conventional dielectric films break down quickly in that environment and quietly drive up costs. We need a domestic supply of advanced materials like next-generation capacitor film to make fusion economically viable.
A few things we put on the record:
– The U.S. manufactures millions of capacitors every year, but imports over a billion pounds of the film that goes inside them. Zero U.S. companies make the production machines. Zero U.S. companies make the polymer resin that goes inside it.
– Fusion plants will depend on capacitor banks that are reliable, replaceable, and cost‑effective over decades. Today’s global supply chain leaves that critical link heavily exposed and tilted toward China.
– PeakNano is currently the only U.S. company producing advanced dielectric film designed for fusion and other high‑power applications, enabling smaller capacitor banks, less maintenance, and lower capital cost per megawatt.
HR 5441 doesn't finance our work. It asks for tax parity, the same tax code treatment other energy technologies receive. The 45X credit sends a signal from the U.S. government that this market is real, that building here is worth the risk. It converts dollars that would otherwise be absorbed by tariffs into new production lines and American jobs.
We're grateful to Representatives Carol Miller and Don Beyer for their bipartisan sponsorship, to the Fusion Industry Association for convening the panel, and to our fellow panelists at Helion, Nucor, and Commonwealth Fusion Systems.
Fusion is moving beyond the physics... it's now a supply chain challenge. Washington is starting to understand that.
