Proxima Fusion invests €140M in domestic production of fusion-grade superconducting tape
German fusion startup Proxima Fusion announced a €140 million investment to build a factory for producing high-temperature superconducting (HTS) tape, a critical component used in its reactor designs. The funding mix includes private capital and public support from the state of Lower Saxony, which is contributing €21 million. HTS tape enables powerful magnetic fields necessary for containing plasma during fusion reactions and has been pivotal to modern fusion technology development. Currently dominated by Asian manufacturers like China and Japan, the global supply chain for HTS tape poses a strategic risk that Proxima aims to mitigate through domestic production. The company’s demonstration plant will require 20,000 kilometers of this material, with commercial reactors needing double that amount. This move aligns with broader efforts in energy innovation as fusion power is expected to consume significant portions of global HTS tape output. The investment follows a recent €411 million funding round for Proxima Fusion and reflects growing confidence in the company’s position within the competitive landscape of fusion startups.
