Tokamak Energy Gains Policy Spotlight And Targets AI Data Centre Power With Superconducting Tech

Tokamak Energy featured prominently this week through two key themes: expansion of its fusion R&D collaboration with U.S. partners and a push to apply its superconducting technology to AI data centres. The company underscored its role in the U.K.–U.S. fusion partnership referenced by King Charles III in his recent address to the U.S. Congress.

Tokamak Energy highlighted a $52 million upgrade to its ST40 tokamak under the LEAPS programme, being delivered with the U.S. Department of Energy and the U.K. Department for Energy Security and Net Zero. The project focuses on radio-frequency heating and lithium plasma-facing components, in collaboration with Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory.

These government-backed initiatives signal growing institutional support for fusion research and may reduce long-term technology and financing risk for the company. The association with high-level policy discussions on clean and secure energy suggests fusion remains a strategic priority in both the U.K. and the U.S., potentially improving Tokamak Energy’s access to grants and partnerships.

At the same time, Tokamak Energy is emphasizing diversification through its TE Magnetics division by targeting AI data centre power distribution. A new study with consultancy The BE Company, presented at the OCP EMEA event in Barcelona, explores using high-temperature superconducting systems in place of conventional copper infrastructure.

The study claims HTS-based power distribution can deliver 3.5× higher power density, about 99% efficiency, and up to 90% fewer power losses in a 10 MW data centre. For operators, this is described as enabling up to 9% more usable IT capacity without additional grid supply and as much as 50% lower total cost of ownership over 15 years.

Tokamak Energy also points to environmental benefits, including up to 90% lower CO₂ emissions, sharply reduced cooling water usage, and up to 98% less copper consumption. These potential advantages position its HTS technology, originally developed for fusion magnets, as a candidate solution for power-hungry AI and high-density data-centre infrastructure.

While the posts do not provide commercialization timelines, contract visibility, or revenue guidance, they highlight a strategy that combines core fusion development with adjacent market opportunities. Overall, the week showcased Tokamak Energy’s increasing policy visibility, strong research partnerships, and early moves to leverage its superconducting expertise beyond fusion, with financial impacts remaining contingent on future technical and commercial milestones.
