Tokamak Energy is a integral leader in fusion energy and high temperature superconducting (HTS) technologies. We work with governments and industry to develop and bring fusion and HTS solutions to market through innovation and strategic partnerships. A major part of this is our end to end capability in HTS systems, from design to manufacturing.
We are the Magnet Systems Partner for the UK Government's STEP Fusion programme, under a £70million contract running to 2029, working with UK Fusion Energy to deliver HTS magnet systems for the STEP prototype power plant, while also contributing to tokamak systems and plasma integration.
Founded in 2009 as a spin-out from the UK Atomic Energy Authority, Tokamak Energy is headquartered in Oxfordshire, with subsidiaries in the United States and Japan. Today, we employ over 300 people and have secured more than £280 million in investment.
We operate through three divisions:
Fusion - Fusion energy technologies, expertise and testbeds for government and private fusion programmes, including ST40, the world’s highest field spherical tokamak.




TE Magnetics - HTS systems for commercial applications including fusion energy, power distribution, life sciences, and propulsion.
Ridgway Machines - Manufacturing equipment for the superconducting, electrical and wider energy sectors, enabling the rapid industrialisation of HTS products.
