Proxima Fusion signs two Japanese partnerships to strengthen Germany's fusion supply chain

German fusion energy firm Proxima Fusion has formed partnerships with Japanese firms Fujikura and Kyoto Fusioneering to bolster its industrial supply chain for commercial fusion power. These Memoranda of Understanding were signed in Tokyo during Chancellor Friedrich Merz's visit to Japan. The agreements cover high-temperature superconducting tape manufacturing, plasma heating, and fusion fuel cycle technologies.

Together, the partnerships aim to enhance Germany's industrial capabilities in fusion energy by integrating Japanese manufacturing expertise. Germany plans to build the world's first fusion power plant, requiring industrial-scale supply chains for specialized components. HTS tape, crucial for compact, high-field fusion magnets, will be produced in Germany under the Fujikura partnership.

Proxima anticipates needing up to 40,000 kilometers of HTS tape for its Stellaris power plants. The Kyoto Fusioneering agreement will advance plasma heating and fuel cycle technologies, with Japan's fusion engineering expertise complementing Germany's stellarator research. Together, these collaborations will build essential industrial foundations for commercial fusion, addressing magnetic confinement, plasma heating, and fuel management.
