Key Takeaways:
A new private-sector consortium aims to build a 400 MWe fusion power plant in the UK, leveraging technology proven in the US.
A trio of companies including Type One Energy, Tokamak Energy, and AECOM have formed a consortium to develop the UK’s first private-sector-led fusion power plant, a 400 MWe project intended to accelerate the country's commercial fusion strategy. The UK Infinity Fusion Consortium will pair Type One Energy’s stellarator reactor design with Tokamak Energy’s magnet technology and AECOM’s infrastructure engineering capabilities.
"Fusion needs to be delivered, not just developed," Chris Mowry, Chief Executive Officer of Type One Energy, said. "By aligning fusion technology, advanced manufacturing, and power plant engineering, we are closing the gap between today’s energy innovation and tomorrow’s energy infrastructure."
The project centers on Type One’s 400 MWe Infinity Two stellarator design, a fusion technology that has been demonstrated to operate in a stable, continuous manner suitable for baseload power, notably at the Wendelstein 7-X project in Germany. Tokamak Energy, a spin-out from the UK Atomic Energy Authority, will provide its high-temperature superconducting (HTS) magnet technology and manufacturing expertise. AECOM, a Fortune 500 infrastructure firm with $16.1 billion in fiscal 2025 revenue, will contribute its capabilities in engineering and managing the delivery of complex energy projects.
This initiative creates a private-sector commercialization path that complements the UK government’s own £2.5 billion STEP (Spherical Tokamak for Energy Production) fusion programme. The consortium plans to leverage experience from the first-of-a-kind Infinity Two plant being developed at the Tennessee Valley Authority’s (TVA) Bull Run site in the US, which is targeting commercial operation in 2034. This transatlantic link provides a strong technical and programmatic foundation, potentially reducing risk and speeding up the timeline for a UK-based plant.
The formation of the UK Infinity Fusion Consortium reflects a broader trend of public-private partnerships in the advanced energy sector, where capital-intensive projects require collaboration. Similar models are emerging in advanced fission, such as Kairos Power's partnership with the TVA and Google to build its Hermes 2 salt-cooled reactor, and Brookfield Asset Management's venture to complete two Westinghouse AP1000 reactors at the V.C. Summer site. These ventures signal a growing consensus that deploying next-generation energy technology at scale requires combining specialized technology, large-scale project management, and significant private capital.
The consortium's members are all part of the Sustainable Markets Initiative (SMI), a network founded by His Majesty King Charles III to accelerate the transition to a sustainable economy. The project aligns with the UK Government's strategy to move from fusion science to commercial deployment and strengthens the UK's supply chain for this critical new energy source. "This government is backing fusion with over £2.5 billion and recently announced a deal with the United States, which includes closer working on fusion research and development," Lord Vallance, UK Minister for Science, Innovation, Research and Nuclear, said.
The stellarator is a fusion device that uses powerful, complex-shaped superconducting magnets to confine hydrogen plasma at temperatures hotter than the sun's core, allowing hydrogen to fuse into helium and release vast amounts of clean energy. Unlike tokamaks, which induce a current in the plasma itself, the stellarator's twisted magnetic fields are generated entirely by external coils, making it inherently stable and capable of continuous operation. The consortium's approach will build on the UK's existing investments in magnetic confinement fusion technology and supply chains developed for the government's STEP programme.
