The UK and US have signed two agreements in a bid to boost commercial fusion. The first agreement will launch a new supercomputing partnership between the UK Atomic Energy Authority and Princeton Plasma Physics Laboratory, combining expertise in AI, computing and fusion to accelerate the development of commercial fusion.
The second agreement saw the two nations sign a Joint Statement committing to closer cooperation on regulating fusion energy, helping to attract investment and support growth of the sector.

Commenting on the agreements, UK Minister for Energy, Michael Shanks, said: “By strengthening our partnership with the US we’re accelerating the race to commercial fusion, turning cutting-edge research into economic growth and cementing Britain’s position as a world leader in fusion energy.”
FCDO Minister for the Americas, Chris Elmore said: “By bringing together world-leading expertise in fusion, artificial intelligence and advanced computing, we’re helping British businesses and researchers access the investment, knowledge and international partnerships needed to succeed in the industries of the future.”
The announcements come as the UK publishes its UK Fusion Investment Prospectus, setting out the UK’s offer for companies and investors and preparing to capture the opportunities in a future global fusion market, and follow the UK government’s £2.5bn investment in fusion under its 2025 strategic review.
