Marathon Fusion, a startup developing fuel processing technology for the fusion industry, announced a fundraise led by 1517 Fund and Anglo American, with participation from Übermorgen Ventures, Shared Future Fund, Malcolm Handley and other leading investors. Alongside a CREATE award from the Department of Energy’s ARPA-E, these investments bring Marathon Fusion’s total funding to $6.9M.

Since its founding in 2023, Marathon Fusion has been dedicated to making improvements to fuel processing efficiency. Its technology allows fusion power plants to operate with less tritium inventory, enabling smaller facilities and improved operational expenses. Now working to commercialize this technology to enable rapid, efficient and high-throughput processing of fusion fuel, Marathon aims to reduce onsite tritium inventories and improve plant economics, helping to ensure that fusion has a path to scale to its full potential.

The new funding will allow Marathon Fusion to accelerate the development and deployment of its fuel processing technology in fusion power plants. The company has signed Letters of Intent with Commonwealth Fusion Systems and Helion Energy, two leading fusion startups aiming for the near-term deployment of fusion power plants.
