Proxima Fusion invests €140M to build factory for fusion‑grade HTS tape

Proxima Fusion announced on Wednesday that it will construct a €140 million (US$162.6 million) factory to produce fusion‑grade high‑temperature superconducting (HTS) tape, a critical component for the company’s next‑generation reactor design. The new facility will be located in the Netherlands and is expected to begin operations in 2025, positioning Proxima as a key supplier of advanced superconducting materials for fusion applications.

The HTS tape, which enables efficient magnetic confinement in fusion reactors, will be manufactured using proprietary processes that Proxima claims deliver higher critical current densities and improved thermal stability compared to existing products. The investment also includes a research and development wing to refine the tape’s performance under the extreme conditions required for sustained fusion reactions. By securing a domestic production line, Proxima aims to reduce lead times and supply chain risks that have historically challenged the fusion industry.

With the factory’s completion, Proxima plans to integrate the HTS tape into its prototype reactor slated for demonstration in 2027. The move is intended to accelerate the company’s path toward commercial fusion power, while also creating a new niche market for high‑performance superconductors in energy and industrial sectors.
