Lower Saxony, Germany Plans to Build Europe's First Large-Scale Fusion-Grade High-Temperature Superconducting Tape Plant

Proxima Fusion and the Lower Saxony state government of Germany signed a memorandum of understanding in Hanover on September 9, planning to build Europe's first large-scale fusion-grade high-temperature superconducting tape production facility in the state, laying the foundation for large-scale industrial production of high-temperature superconducting (HTS) tape. According to the plan, the first two phases of the project involve an investment of approximately 140 million euros, with public funds and private capital each covering about half. Of this, Lower Saxony plans to contribute 21 million euros, accounting for nearly 30% of the public funding portion. The first two phases of construction are expected to be completed by the end of 2029. High-temperature superconducting tape is a type of metal tape that exhibits superconducting properties at relatively higher temperatures. In the superconducting state, it can transmit current with nearly zero resistive loss and is used to manufacture high-power, compact electromagnets. For stellarator fusion devices, magnets made from high-temperature superconducting tape can generate the magnetic fields needed to confine and control high-temperature plasma, making them an important foundational material for achieving compact fusion devices and future fusion power plants.

SuperMag New Energy Achieves Milestone Progress in Development of 25 T-Class High-Temperature Superconducting Toroidal Field Model Magnet

Recently, SuperMag New Energy has achieved two milestone progresses in the development of its 25 T-class high-temperature superconducting toroidal field model magnet: following the completion of R&D and testing of the first panel-type high-temperature superconducting single pancake coil, the company has initiated batch manufacturing of panel-type single pancake coils; meanwhile, the self-developed 24 cm² low-resistance detachable joint has completed prototype fabrication and performance testing in the liquid nitrogen temperature range, with an equivalent joint resistance of approximately 33 nΩ. These two progresses correspond to two critical aspects: stable manufacturing of single pancake coils and low-loss interconnection of multiple units. The project has advanced from the single-component process validation stage toward multi-pancake manufacturing and model magnet system integration. The single pancake coil is not an ordinary component in the model magnet, but rather a fundamental unit integrating conductor, panel structure, insulation, electrical connection, and testing interfaces. Each single pancake requires independent manufacturing and inspection, and also serves as the foundation for subsequent multi-pancake stacking, magnet excitation, and cryogenic operation.
