Proxima Fusion announced plans to build a €140 million facility dedicated to manufacturing high-temperature superconducting (HTS) tape, a crucial component for its fusion reactor technology. The Germany-based company intends to use a combination of public and private funding for the project, including a €21 million contribution from the state of Lower Saxony. HTS tape is essential for generating the strong magnetic fields needed to contain plasma in fusion reactions. Proxima's demonstration reactor will require approximately 20,000 kilometers of this tape, with commercial plants needing even more. Currently, most HTS tape production is concentrated in China and Japan. The development of HTS tape over the past decade has been pivotal for fusion startups, enabling smaller and more efficient reactor designs by producing strong magnetic fields at relatively higher temperatures. Beyond fusion, HTS tape is also being explored to enhance the efficiency of data centers. Proxima Fusion's investment reflects a strategic effort to secure supply chains and advance fusion energy technology.
