GoKawiilProxima Fusion to build €140M superconducting tape factory in Germany
Proxima Fusion announced plans to construct a €140 million ($162.6 million) plant to manufacture fusion-grade high-temperature superconducting tape, a critical material for containing plasma in its reactors. The factory will be funded through a mix of public and private money, including €21 million from the state of Lower Saxony, and follows a €411 million funding round the startup closed months earlier.
GoKawiil's interpretation of the reporting above, not reported fact.
Currently China and Japan produce nearly all the world's HTS tape supply, creating a potential bottleneck for Western fusion developers who need vast quantities of the material to build reactors. By localizing production, Proxima aims to secure its supply chain for both its demonstration plant and future commercial reactor, which will require tens of thousands of kilometers of tape.
- Proxima Fusion will spend €140 million building its own HTS tape factory in Germany.
- The material is essential for generating magnetic fields that contain plasma in fusion reactors.
- Asian manufacturers currently dominate global HTS tape production, posing supply risks for Western fusion startups.
