A consortium led by Type One Energy, Tokamak Energy, and AECOM has formed in the United Kingdom to pursue the development of a 400 MWe fusion power plant, a specific, measurable step toward commercially viable fusion energy. Combining Type One Energy’s stellarator design with AECOM’s engineering and Tokamak Energy’s high-temperature superconducting magnet technology and manufacturing expertise, the UK Infinity Fusion Consortium aims to complement the government’s STEP Fusion programme and attract private capital. This initiative coincides with increased U.S.-U.K. collaboration on fusion; His Majesty King Charles III recently stated during an address to the U.S. Congress that, “Our nations are combining talent and resources in the technologies of tomorrow—our new partnerships in nuclear fusion and quantum computing.” Chris Mowry, Chief Executive Officer of Type One Energy, emphasizes the need to deliver fusion, not just develop it, positioning this consortium as a pathway to real-world deployment.
UK-US Collaboration Drives Fusion Energy Development
The newly formed UK Infinity Fusion Consortium signals a determined push toward commercially viable fusion power, aiming to deliver a 400 MWe stellarator power plant design, the Infinity Two, through a transatlantic partnership. This builds on the UK’s existing investment in magnetic confinement fusion, supply chain development, and regulatory frameworks. The project will also draw upon experience gained from the Infinity Two plant currently under development at the Tennessee Valley Authority’s Bull Run site in the United States, which is slated for commercial operation.
Type One Energy’s 400 MWe Infinity Two Stellarator Design
The pursuit of commercially viable fusion energy is rapidly evolving from publicly funded research into private enterprise, with several ventures now aiming to deliver functional power plants within the decade. This targeted electrical output establishes a clear benchmark, positioning the Infinity Two plant as a substantial contributor to future energy grids and providing a concrete scale for comparison against other fusion initiatives currently under development. The consortium’s approach leverages existing technological strengths; Tokamak Energy brings established high-temperature superconducting magnet technology and manufacturing expertise to the project, building directly on their contributions to the UK’s STEP Fusion programme. This focus on readily available capabilities distinguishes the consortium’s strategy, aiming for a deployable solution rather than relying on unproven innovations. This private sector initiative receives support from high-level diplomatic engagement; His Majesty King Charles III highlighted U.S.-U.K. collaboration on fusion during his address to the U.S.
Type One Energy, Tokamak Energy and AECOM have come together as members of the SMI, demonstrating the SMI’s Terra Carta and Astra Carta mandates in action – business and finance working together to turn breakthrough innovation into measurable progress in building a more sustainable future.

HTS Magnet Technology & UK Supply Chain Expansion
Tokamak Energy is central to bolstering the United Kingdom’s position in advanced fusion technology, specifically through its expertise in high-temperature superconducting magnet technology and associated manufacturing capabilities. These capabilities are being directly integrated into the UK Infinity Fusion Consortium, formed with Type One Energy and AECOM to develop the first privately-led fusion power plant within the country. The consortium aims to deploy a commercially viable plant utilizing Type One Energy’s 400 MWe Infinity Two stellarator design, with Tokamak Energy providing the advanced magnets essential for containing the superheated plasma.
Warrick Matthews, Chief Executive Officer of Tokamak Energy, emphasized the significance of this integration, stating that the consortium “puts Tokamak Energy’s transformative magnet technology and manufacturing expertise” into a “world-class fusion programme.” He continued, “Together, we can accelerate towards commercializing a new form of limitless, clean energy and, in combination with our role as STEP magnet systems partner, strengthen the UK supply chain’s leadership in global fusion.” The consortium’s ambition extends beyond demonstrating fusion; it seeks to establish a fully-fledged commercialization pathway, complementing the government-led STEP initiative and accelerating the growth of the UK fusion supply chain.
Lord Stockwood, UK Minister for Investment, affirmed the importance of this private sector involvement, noting that the consortium will “play a key role in new fusion projects, creating exciting opportunities for people in local communities.” This coordinated effort aims to position the UK as a global leader in both fusion science and its practical application, strengthening the nation’s industrial base and contributing to net-zero goals.
This Consortium puts Tokamak Energy’s transformative magnet technology and manufacturing expertise in the centre of another world-class fusion programme. Together, we can accelerate towards commercialising a new form of limitless, clean energy and, in combination with our role as STEP magnet systems partner, strengthen the UK supply chain’s leadership in global fusion.
