## About

Based in California, US, and founded in 2023, Marathon Fusion is a company that includes fuel processing in fusion power plants. In July 2024, Marathon Fusion raised USD 5.9 million in seed funding co-led by investors 1517 Fund and Anglo American, with participation from other investors Übermorgen Ventures and Shared Future Fund. As of November 2024, the company is led by CEO Kyle Schiller.

Marathon Fusion’s primary product is its superpermeable hydrogen pump, a technology to improve the tritium processing cycle. This pump leverages plasma technology and separation membranes to expedite the processing of tritium, an isotope crucial for fusion reactions. The technology addresses two critical needs: reducing the complexity of existing systems and enhancing the utilisation of scarce isotopes. The firm approach includes integrating technologies into a consolidated fuel cycle framework.

The company will use the July 2024 funding to expand its operations and development.
