Proxima Fusion to build €140M factory for high-temperature superconducting tape
Key points
- Proxima Fusion will build a €140 million HTS tape factory.
- HTS tape is critical for fusion reactor magnetic fields.
- The factory will reduce reliance on Asian suppliers.
- Lower Saxony is contributing €21 million to the project.
New Factory for Fusion Component
Proxima Fusion, a Germany-based fusion startup, plans to build a €140 million factory dedicated to producing fusion-grade high-temperature superconducting (HTS) tape. This facility will provide a crucial component for the company's fusion reactor designs.
Strategic Supply Chain Investment
The decision to build the factory follows Proxima Fusion's recent €411 million funding round. The investment aims to secure the supply of HTS tape, which is predominantly manufactured in China and Japan. The state of Lower Saxony will contribute €21 million to the project, with additional funding from public and private sources.
Role of HTS Tape in Fusion
HTS tape is essential for generating the powerful magnetic fields required to contain the plasma in fusion reactions. Proxima Fusion's demonstration plant will use 20,000 kilometers of HTS tape, with commercial power plants requiring twice that amount. HTS tape enables smaller and more efficient reactor designs due to its ability to create strong magnetic fields at relatively high temperatures.
Broader Industry Impact
HTS tape emerged over a decade ago as a fundamental breakthrough for the current generation of fusion power startups. Beyond fusion, companies like Veir are utilizing HTS tape to improve the efficiency and power density of data centers, indicating its broader applications in high-tech industries.
