Furukawa Electric, SuperPower's parent, and Tokamak Energy signed an agreement at 10 Downing Street to begin research, prototyping and a feasibility assessment of HTS tape manufacturing in the UK. Any UK production depends on the results of these studies. The UK's STEP prototype fusion plant, targeted for 2040, is expected to need about 30,000 km of HTS tape.

## Key facts

- Signed 14 June 2026, alongside the launch of a UK-Japan Frontier Technology Partnership.
- Scope: R&D, prototyping and feasibility of manufacturing processes and UK options.
- STEP is expected to use about 30,000 km of HTS tape.
- Furukawa invested in Tokamak Energy in December 2023.
