Marathon Fusion secures $5.9 million in seed funding to innovate tritium production technologies, targeting critical challenges in the emerging nuclear fusion industry.

Information on the Target

Marathon Fusion is a pioneering startup focused on overcoming critical challenges in nuclear fusion energy, particularly related to the production of tritium, a vital isotopic fuel. Tritium, which is needed in significant quantities for commercial nuclear fusion reactors, is currently in limited supply, with only around 20 kilograms available worldwide. CEO Kyle Schiller emphasizes that this scarcity poses a significant obstacle for the development of multiple fusion power plants. Marathon Fusion aims to address this issue through innovative technologies that enhance the extraction and production of tritium.

The company seeks to refine a 40-year-old technology known as superpermeation, which employs solid metal membranes to efficiently filter hydrogen and its isotopes from other impurities. This process not only maximizes throughput but also compresses hydrogen as it passes through the membrane, further streamlining the generation of required fuels for reactor operations.

Industry Overview in the Target’s Specific Country

The nuclear fusion sector is currently gaining momentum, accompanied by substantial investments and research efforts in the United States. While traditional fission reactors have been the cornerstone of nuclear energy for
