Tokamak Energy has installed its SOPHIA software programme for students as part of a UK-first nuclear training facility, unveiled today.

Funded through a £2 million grant from the Office for Students, the ‘Lancaster University Nuclear Operations Simulator’ will support teaching across a range subjects such as nuclear engineering and cyber security to support the nation’s clean energy goals and address critical skills gaps.

The creation of this cutting-edge facility, which includes a huge wrap-around screen and multiple lay-outs, is aligned to the UK’s Modern Industrial Strategy and National Nuclear Strategic Plans by supporting teaching across undergraduate and postgraduate Lancaster University programmes.

It comes equipped with a highly reconfigurable design and software for different reactor types including a pressurised water reactor (PWRs), small modular reactor (SMRs), and fusion reactor, with software codes developed by GSE Solutions, Westinghouse, Norway’s Institute for Energy Technology, and Tokamak Energy.

It also includes leading-edge audio-visual equipment that can be used to flexibly configure different scenarios and record student interactions in the simulation environment.

Professor Rebecca Lingwood, Deputy Vice-Chancellor at Lancaster University, said: “This fabulous new facility will augment Lancaster’s long-established strength across disciplines such as nuclear engineering and cyber security, providing our students with a truly excellent learning experience. Lancaster University plays a vital role as an economic anchor institution in north-west England, and this facility will further enable us in helping to deliver a new generation of young people equipped with the skills needed to support a low-carbon energy sector vital for national energy security.”

Tokamak Energy’s SOPHIA, the Greek goddess of wisdom, was originally developed to predict, simulate and validate experiments in the company’s record-breaking machine ST40 – a vital testbed for developing the technologies and expertise required to deliver commercial fusion. It allows scientists and engineers to get maximum gains from every experiment without needing to test multiple scenarios in the physical machine – which reaches plasma temperatures six times hotter than the centre of the sun – removing human error and fast-tracking results.

Ross Morgan, Tokamak Energy’s Fusion Managing Director, said: “This is a fantastic initiative by Lancaster University that we are extremely proud to support. Young people are more aware than ever that the world needs a new supply of clean, secure energy. We hope our tokamak simulator SOPHIA will inspire students to pursue a career in fusion energy and help make the world a better place for future generations.”

The facility will be ready for teaching students at Lancaster University from the next academic year starting in the autumn. It will be an invaluable teaching tool to enable students to put into practice some of the theory from their undergraduate, master’s and doctorate courses.

Tokamak Energy has world-leading expertise in fusion technologies and is the Magnet Systems Partner for the UK’s flagship STEP programme.

This work builds on the longstanding relationship between Furukawa Electric and Tokamak Energy, as well as ongoing discussions regarding the role HTS technology could play in areas such as fusion energy, power transmission, and medical devices.

The agreement was signed at a formal ceremony in 10 Downing Street yesterday where Prime Minister Keir Starmer and his Japanese counterpart Sanae Takaichi launched a new UK-Japan Frontier Technology Partnership to accelerate cooperation on the technologies of the future.

Founded in Tokyo in 1884, Furukawa Electric Group provides a broad range of technologies, products, and services in infrastructure, automotive systems, and electronics. The company has long contributed to innovation in superconducting technologies and, since the 1960s, has developed low-temperature superconducting (LTS) wires for fusion experimental reactors, including ITER. Through its U.S. subsidiary SuperPower Inc., the Group has also developed and commercialised HTS tape for applications in energy, medical, and research fields.

Founded in 2009 as a spin-out from the UK Atomic Energy Authority, Tokamak Energy is a global leader in HTS and fusion technologies, with end-to-end capability in developing HTS systems from design to manufacturing. Headquartered in Oxford, with subsidiaries in the United States and Japan, the company works with governments and industry to develop and bring HTS and fusion solutions to market through innovation and strategic partnerships. Through its TE Magnetics division, Tokamak Energy is creating commercial opportunities for HTS applications, while also contributing to the development of advanced fusion systems.

Tokamak Energy also plays an important role in the UK’s fusion ecosystem. In April 2026, it was named Magnet Systems Partner for the UK Government’s STEP Fusion programme under a £70 million contract running to 2029. Through this work, the company is collaborating with UK Fusion Energy (UKFE) on the HTS magnet system for the STEP prototype power plant, while also contributing to tokamak systems and plasma integration. STEP is a UK-led programme that brings together government and industry to develop fusion energy and accelerate its pathway towards deployment. In building a prototype fusion power plant by 2040 it is expected to use an estimated 30,000 km of HTS tape.

As part of the collaboration between Furukawa Electric and Tokamak Energy, the companies are moving forward with an initial programme focused on tape research, development, prototyping, and feasibility assessment, including evaluation of manufacturing processes and future options in the UK. Subject to the outcome of these studies, this work could help lay the groundwork for future HTS tape manufacturing capabilities in the UK.

Furukawa Electric and Tokamak Energy have received letters of support from the UK Government and UK Fusion Energy (UKFE). The UK Government has expressed support for the companies’ emerging plans to develop HTS tape capability in the UK and its intention to continue working with the companies as those plans evolve. UKFE, which leads the STEP programme, has also expressed support for the development of UK-based HTS tape capability and its potential importance for future fusion development.

Furukawa Electric entered into an investment agreement with Tokamak Energy in December 2023, building on a longstanding strategic partnership aimed at realising zero-carbon, safe and secure fusion energy. This latest initiative reflects the two companies’ shared ambition to unlock the potential of HTS technologies in support of the future growth of the fusion ecosystem and wider industrial applications.

Hideya Moridaira, President and CEO of Furukawa Electric Co., Ltd., said: “We have long been dedicated to the research and development of superconducting technologies, applying them across a wide range of fields. We are encouraged by the potential of this collaboration with Tokamak Energy and look forward to exploring how HTS capability — including future HTS tape manufacturing capabilities — could be developed in the UK.”

Warrick Matthews, CEO of Tokamak Energy Ltd, said: “Tokamak Energy has built a strong relationship with Furukawa Electric in recent years, and we greatly value the expertise the company brings in superconducting technology and manufacturing. Together, we are exploring how HTS tape capability in the UK could help commercialise fusion energy and unlock new levels of performance in a range of other industries, while strengthening our future HTS systems manufacturing capabilities.”

Lord Vallance, Minister for Science, Innovation, Research and Nuclear, said: “Britain is a world-leader in the fusion industry and this partnership between Furukawa Electric and Tokamak Energy will develop crucial capability to drive forwards progress in fusion energy. This is supported by our Fusion Strategy, helping to secure our future energy independence, champion innovation and research, and provide the skilled clean energy jobs of the future for British people.”

Dan Bishop OBE, UKFE’s Chief Commercial Officer, said: “UKFE welcomes this collaboration, the close working between Furukawa Electric and Tokamak Energy as our Magnets Partner, and the opportunity it presents to strengthen partnerships and explore pathways towards future HTS capability in the UK in support of a secure, sustainable, safe, cost-effective national energy supply.”

Fusion energy requires strong magnetic fields to confine and control extremely hot hydrogen fuel in the form of plasma. These magnetic fields are generated using advanced magnet systems, in which HTS tapes play an important role. HTS materials can enable high current density, strong magnetic fields, and improved performance across a range of next-generation applications.

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.

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.

Launched in 2023, the Defense Advanced Research Project Agency (DARPA)’s Principles of Undersea Magnetohydrodynamic Pumps (PUMP) programme was initiated with a view to creating novel electrode materials suitable for a magnetohydrodynamic (MHD) drive.

The contract with General Atomics will see Tokamak Energy provide the simulation, design and fabrication of the HTS magnets.

General Atomics will provide magnet system integration with auxiliary systems and integration with prime contractor HRL Laboratories, who are developing the electrode technology needed to overcome existing performance limitations. These combined efforts bring together capabilities that address challenges which have previously made the technology unviable due to limitations in magnets and electrodes.

HTS is the ideal technology to be deployed for MHD as propulsion in water requires high magnetic fields in a compact package, and HTS technology is capable of enabling a more powerful, silent and efficient MHD drive.

Tokamak Energy is delivering this technology by leveraging its proprietary suite of modelling and simulation tools validated through extensive magnet testing, patented designs that enable robust magnets and versatile manufacturing technologies born from its mission to deliver clean and limitless fusion energy.

Dr Liam Brennan, Director of TE Magnetics, Tokamak Energy’s specialist business division, said: “This contract is another step towards realising a military relevant scale magnetohydrodynamic drive, and we are delighted to be working with General Atomics on this important project. We’re excited to demonstrate how our HTS technology, born from our mission to deliver limitless, clean fusion energy, can enable a broad range of applications with significant industrial and commercial value across a range of sectors.”

“We are proud to be part of this groundbreaking collaboration and to provide our expertise in advanced magnet system integration,” said John Smith, senior director of Projects and Engineering for General Atomics Energy Group. “Our work with Tokamak Energy and HRL Laboratories shows how the unique strengths of each collaborator can overcome long-standing barriers in magnetohydrodynamic propulsion. At General Atomics, we have a proven record of delivering complex technologies for national security, energy, and scientific discovery, and this project highlights how our capabilities extend across multiple applications to strengthen U.S. leadership in innovation.”

Tokamak Energy launched TE Magnetics to focus on the industrial deployment of transformative HTS technology in September 2024.

MHD pumps generate force from a magnetic field acting on an electric current flowing through seawater, requiring no rotating mechanical components. This approach reduces noise while increasing reliability in comparison to conventional propeller- or impeller-based systems.

Tokamak Energy has made advances in rare-earth barium copper oxide (REBCO) superconducting material, and its advanced winding, testing and production techniques are the key to creating robust and reliable HTS magnets. Its HTS materials have demonstrated large-scale magnetic fields as high as 24 Telsa and will be critical in yielding an efficient MHD drive. The PUMP programme is a 42-month effort that aims to solve the electrode materials challenge.

Tokamak Energy does not have a contractual relationship with the U.S. Government on this program.

Ridgway Machines, founded in 1920, develop solutions for winding and insulating superconducting magnets and cables, and will enable TE Magnetics to scale up its UK manufacturing facilities to produce commercial products fit for multiple industries.

Warrick Matthews, Tokamak Energy CEO, said: “Since launching the TE Magnetics brand, we have been successful in securing contracts for a range of HTS products and it is now time to scale up. The acquisition of Ridgway Machines, a thriving business with a highly skilled workforce, will accelerate TE Magnetics’ manufacturing method development to deliver high quality products at scale.

“Ridgway’s specialist engineering capabilities combined with TE Magnetics’ world-leading HTS design and prototyping knowledge will deliver breakthroughs in performance, efficiency, and accessibility across a wide range of industries, helping to address global challenges and accelerate the electric revolution.”

Andy Glanville, Ridgway Machines Managing Director, said: “Throughout our hundred-years history, Ridgway has always been forward looking. This track record means we are well suited to expansion and this new period of growth. In Tokamak Energy, we’re proud to be joining one of the UK’s most exciting technology businesses and to play our part in their ambitious and transformative plans.

“Both businesses exist to provide innovative solutions to some of the most pressing and important technological challenges the world is facing, and we can’t wait to get started on new projects together.”

HTS materials conduct electricity with virtually no power loss. When engineered into magnets, they generate exceptionally strong and stable magnetic fields within compact, lightweight systems – unlocking new possibilities in fusion energy and other applications ranging from electric zero emission flight to analytical science.

Tokamak Energy has pioneered HTS magnets since 2012, long before their importance for delivering clean, limitless fusion energy was widely recognised. Its advanced winding, testing and production techniques are key to creating robust and reliable HTS magnets for many industrial applications, including fusion, science and medicine, power systems, power distribution, manufacturing, and propulsion for land, water, air and space.
