Together, the companies intend to develop a fusion project that is commercially credible, deployable using existing enabling technologies, and capable of attracting private capital — consistent with the long-term goals of the government’s recently announced UK Fusion Strategy.

This announcement comes at a time of increasing U.S.-U.K. bilateral cooperation on fusion. His Majesty King Charles III said during his address to the United States Congress last week that, “Our nations are combining talent and resources in the technologies of tomorrow — our new partnerships in nuclear fusion and quantum computing, and in AI and drug discovery, holding the promise of saving countless lives.”

The Consortium partners are all members of the Sustainable Markets Initiative (SMI), a global CEO-led network founded by His Majesty King Charles III with the mandate to lead the private sector in accelerating the transition to a sustainable economy.

At its core, the UK Infinity Fusion Consortium combines Type One Energy’s 400 MWe Infinity Two stellarator fusion power plant design, AECOM’s leading engineering capabilities, and Tokamak Energy’s HTS magnet technology and manufacturing expertise in the UK. The Consortium will use these capabilities to develop a UK Infinity Two fusion power plant project that will include participation by the broader UK fusion value chain spanning construction, finance, offtake and other supply chain partners.

The Consortium will build on the UK’s significant investment in magnetic confinement fusion technology, supply chain capabilities, regulation, and power plant siting for the government’s STEP Fusion programme. It will also capitalise on the synergy and experience gained from the first-of-a-kind (FOAK) Infinity Two fusion power plant project at the Tennessee Valley Authority’s (TVA’s) Bull Run site in the United States, which is targeted for commercial operation in 2034. The TVA Infinity Two project is being supported by the U.S. government’s own fusion programmes and provides a strong technical and programmatic foundation for the UK Infinity Two deployment project.

The development of a UK Infinity Two fusion power plant project by the Consortium is aligned with the UK Government’s strategy to move from world-leading fusion science to commercial deployment — a strategy guiding the STEP Fusion programme. The Consortium will create a private-sector-led fusion commercialisation pathway complementing the STEP Fusion programme. The UK Infinity Two project further scales growth of the UK fusion supply chain and accelerates time-to-market for this critical new energy source, while strengthening the country’s industrial base.

Chris Mowry, Chief Executive Officer, Type One Energy, said: “Fusion needs to be delivered, not just developed. This Consortium brings together the core industrial capabilities in the UK and US required to deploy real-world fusion power plant projects that are commercially viable. 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. Our initiative is fully aligned with UK and US ambitions to be leaders in commercial fusion deployment.”

Warrick Matthews, Chief Executive Officer, Tokamak Energy, said: “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.”

Troy Rudd, Chairman and Chief Executive Officer, AECOM, said: “Fusion represents one of the most important long-term energy solutions, offering a clean, safe and reliable source of power for future generations. Delivering on fusion’s potential requires disciplined engineering, well-established infrastructure delivery models and collaboration across the entire energy ecosystem. Through this Consortium, AECOM is bringing its global experience in complex energy infrastructure to help lay the groundwork for commercial fusion projects that can scale with confidence, supporting the UK’s energy system while strengthening its industrial and infrastructure base.”

Lord Vallance, UK Minister for Science, Innovation, Research and Nuclear, said: “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, taking us closer to a future powered by limitless clean energy. Our long-term vision and investment in the sector is now helping turn that ambition into reality.”

Lord Stockwood, UK Minister for Investment, said: “The UK is a world leader in renewables, and this consortium will play a key role in new fusion projects, creating exciting opportunities for people in local communities. We’re serious about the benefits three of clean energy technologies, which is why our modern Industrial Strategy is attracting investment into the sector to boost economic growth as the UK powers towards net zero.”

Jennifer Jordan-Saifi, CEO of the Sustainable Markets Initiative (SMI) said: “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.”

The company ended 2025 by achieving its highest plasma current, highest stored energy, and highest fusion triple product – all key measures on the path to delivering clean, limitless fusion energy.

The compact spherical tokamak at the company’s Oxfordshire HQ is now preparing for a major upgrade for a new campaign of ground-breaking experiments in partnership with the U.S. Department of Energy (DOE) and the UK Department for Energy Security and Net Zero (DESNZ).

Otto Asunta, Tokamak Energy Experiments Chief for ST40, said: “These superb results are a great way to finish the year and demonstrate how the ST40 team continues to push the limits, improving the already impressive performance of our compact high-field device.

“Breaking into the mega-amp range with our plasma current is a major milestone as we continue to build our knowledge of what will be needed for delivering fusion energy to future grids. We now look forward to working with the U.S. and UK governments on a new wave of experiments to deliver more cutting-edge science with our industry-leading device that has always punched above its weight.”

ST40 set a new record by reaching 1 MA (1,000,000 amperes) of plasma current, surpassing its previous best of 0.85 MA, while stored energy was nearly doubled compared to previous campaigns. This demonstrates that a plasma volume of just one cubic metre can hold immense power – an important insight on the path to energy-producing devices.

Plasma current – the electric current flowing through the plasma inside a tokamak – is crucial for confinement. It generates a poloidal magnetic field that, together with the magnetic fields from coils, keeps the plasma confined and away from material surfaces inside a tokamak. In future devices, a high plasma current is required to also trap the fusion-born alpha particles.
The fusion triple product, a measure combining plasma temperature, density, and energy confinement, is a key indicator of plasma performance.

In the company’s record-breaking 100 million degrees Celsius campaign of 2022, ST40 achieved a triple product of approximately 6 ± 2 × 10¹⁸ m⁻³·keV·s, the highest ever achieved in a privately-owned tokamak. Following an extensive series of experiments at plasma currents >800 kA and toroidal field 2.1 T, the team improved its previous best by a third to ~8 ± 2 × 10¹⁸ m⁻³·keV·s, demonstrating significant progress in plasma performance by operating in H-mode (high-confinement mode).

The latest campaign also saw the implementation of a new software called RT-GSFit that can reconstruct the plasma shape during a pulse at a millisecond time resolution (a thousand times per second). Integrating RT-GSFit into the ST40 Plasma Control System allowed the team to control plasma shape in real-time.

ST40 has now paused operations for the $52 million upgrade programme, known as LEAPS (Lithium Evaporations to Advance PFCs in ST40), in partnership with DOE and DESNZ. The programme will apply lithium coatings to all plasma-facing components (PFCs) using a lithium evaporation technique, building on pioneering work by Princeton Plasma Physics Laboratory and others that has shown lithium PFCs can significantly improve plasma performance.

The ultimate goal is to enable fusion conditions with good confinement that is compatible with sustainment for long durations in a future fusion pilot plant.

The company was praised for its transformative work in the development of compact, powerful, robust, quench resilient, high temperature superconducting (HTS) technology.

HTS is essential for commercialising clean, limitless fusion energy, and will support the UK Government in addressing constraints in the national grid exacerbated by power demand for AI and data centre infrastructure.

Established in 2024, Tokamak Energy’s TE Magnetics division is leading the company’s HTS development and commercialisation for a range of applications, from power distribution, electric motors for zero emission flight, and fast, efficient magnetic levitation transport systems.

Warrick Matthews, Tokamak Energy CEO, said: “We have designed, built, and operate two of most advanced fusion energy research devices in the world – ST40 and Demo4.

“The teams behind these machines are driving the development and commercialisation of clean, limitless energy and transformative superconducting technologies for applications in fusion, science, power systems, propulsion, and beyond. We are proud to accept this prestigious award on behalf of all our people at Tokamak Energy, recognising their outstanding work to deliver positive impact through ground-breaking technology.”

The IOP is the professional body and learned society for physics in the UK and Ireland. With a rich history of supporting business innovation and growth, it is committed to working with ‘physics-powered’ businesses, and companies that apply and employ physics and physicists.

Michele Dougherty, Institute of Physics President Professor, said: “Physics drives discovery and innovation, transforming our understanding of the world. And it is the innovations of physics-powered businesses that are driving our economy, creating jobs and addressing the challenges that face us today.

“In the coming years, physics will continue to shape our lives, hopefully making a better world for us all, and it is companies like those we are honouring with a 2025 IOP Business Award that are leading the way towards a prosperous, sustainable future. My sincerest congratulations to them all. “

Demo4 also demonstrates the transformative potential of high temperature superconducting (HTS) technology across a range of spin-out applications, from power distribution for data centres, electric motors for zero emission flight, and fast, efficient magnetic levitation transport systems.

Creating fusion energy requires extremely strong magnetic fields to confine and control hydrogen fuel, which is heated to a plasma several times hotter than the centre of the sun inside a vessel called a tokamak.

Tokamak Energy’s Demo4 – a complete set of HTS magnets built in a tokamak configuration – produced the milestone results at the company’s headquarters outside Oxford, achieving field strengths of 11.8 Tesla at -243 degrees Celsius in recent tests.

The world-first system had an incredible seven million ampere turns of electrical current running through its centre column, demonstrating huge potential for power distribution as HTS can deliver around 200 times the current density of copper.

Warrick Matthews, Tokamak Energy CEO, said: “These results are a major victory for the race to deliver fusion and HTS as a disruptive new commercial technology. Demo4 represents over a decade of HTS innovation at Tokamak Energy. Born from our fusion mission, it validates one of the technical solutions for getting clean, limitless, safe and secure fusion energy on the grid.

“Demo4 is also best in class at showcasing and demonstrating the transformative potential for superconductors, including power distribution for high-demand environments like data centres and applications across science, power systems, propulsion, and beyond.”

Strong magnetic fields are generated by passing large electrical currents through arrays of electromagnetic coils assembled in a cage-like formation. The magnets are wound with precision from HTS tapes using multi-layered metal conductors with a crucial internal coating of ‘rare earth barium copper oxide’ (REBCO) superconducting material.

While recognising the achievement of demonstrating a single high-field HTS magnet, Tokamak Energy has focused on the next essential step: validating a complete HTS magnet system. In a fusion power plant, each REBCO superconducting tape must operate within the complex, combined magnetic environment created by neighbouring coils – conditions that significantly influence its effective critical current and structural performance.

These system-level interactions cannot be captured through individual magnet tests. Demo4 is therefore a world-first high field platform to generate and study fusion-relevant forces across a system coil set (14 toroidal field magnets and two poloidal field magnets), providing uniquely valuable engineering insight and data to inform power plant designs of the future.

Graham Dunbar, Demo4 chief engineer at Tokamak Energy, said: “Demo4 is delivering exactly what it was built for. Every test provides us with invaluable data and deepens our understanding. This isn’t just about achieving a number; it’s about gaining the confidence and build expertise to scale our technology for future energy-producing fusion systems.”

Demo4’s results confirm Tokamak Energy’s HTS magnets can generate the high fields essential for a fusion power plant and prove their capacity to support higher current densities with plug-in cooling capability. This means they can be made smaller and lighter than traditional low-temperature superconductors and operate at a fraction of the cooling cost. Further testing to reach higher magnetic fields continues, with next results due in early 2026.
