UK and US deepen fusion and AI partnership

Britain and the United States are set to formalise two agreements at the Global Fusion Summit in London to deepen cooperation on fusion power and AI. One accord will create a supercomputing partnership between the UK Atomic Energy Authority and the Princeton Plasma Physics Laboratory, combining AI, advanced computing and fusion research to speed work toward commercially viable clean energy.

The governments also plan a joint statement on closer regulatory alignment for fusion energy, which officials say could support investment and sector growth. Fusion, which recreates the process that powers the sun by combining hydrogen isotopes under extreme heat, is viewed as a potential zero-carbon power source, though no experimental reactor has yet produced net energy output.

Energy minister Michael Shanks said fusion could support more than 10,000 jobs across the UK by 2030, while foreign minister Chris Elmore said the partnership would help British firms and researchers access investment and international expertise. The collaboration comes despite broader differences over energy policy, with the Trump administration backing fossil fuels while sharing UK ambitions on nuclear fission and fusion.

Additional UK activity includes £2.63 million for fusion materials work involving the University of Birmingham, the Electric Power Research Institute and commercial partners, plus up to £3 million from Kyoto Fusioneering through “Project Albion”. The UK is also publishing an investment prospectus for a future fusion market estimated to be worth between £3 trillion and £12 trillion, following a Government pledge of £2.5 billion over a five-year timeframe.
