Type One Energy, Tokamak Energy and AECOM have formed the UK Infinity Fusion Consortium to develop the first privately-led fusion power plant project in the UK. The initiative aims to create a commercially credible, deployable fusion project using existing technologies and capable of attracting private capital, aligning with the UK government’s recently published UK Fusion Strategy.
The consortium will centre on Type One Energy’s 400 MWe Infinity Two stellarator design, AECOM’s engineering and infrastructure delivery capability and Tokamak Energy’s high‑temperature superconducting (HTS) magnet technology and UK manufacturing expertise. The UK Infinity Two project is intended to integrate the wider British fusion value chain, including construction, finance, offtake arrangements and local supply chain partners.
The effort builds on the UK’s investment in magnetic confinement fusion, regulation, supply chain development and the siting work underway for the government‑led STEP Fusion programme. It also draws on the US-based TVA Infinity Two project at the Bull Run site in Tennessee, where the same stellarator design is targeted for commercial operation in 2034 under the US fusion development framework.
Consortium leaders say the UK Infinity Two project will create a parallel, private sector path to commercial fusion, complementing STEP and accelerating the UK’s move from world‑leading fusion science to commercial deployment. The collaboration is also framed as a symbol of deepening US–UK fusion cooperation, reinforced by King Charles III’s recent remarks on bilateral partnership in fusion and other emerging technologies during his address to the US Congress.
Executives from Type One Energy, Tokamak Energy and AECOM emphasised that the initiative is designed to translate cutting‑edge fusion science into scalable, real‑world power plants, while the UK government pointed to the project as evidence that its £2.5 billion fusion commitment is beginning to turn ambitious research into tangible infrastructure.
