Tokamak Energy Ltd is a UK-based private fusion technology company headquartered at Milton Park, Oxfordshire. It develops compact spherical tokamak reactors and high-temperature superconducting (HTS) magnet systems to advance magnetically confined fusion as a future source of low-carbon electricity and high-grade process heat.
The company designs, manufactures, and tests HTS magnets and cryogenic systems, and operates experimental fusion facilities to validate plasma confinement and power-plant enabling technologies. Working with academic, industrial, and government partners, Tokamak Energy is pursuing a pathway toward pilot-scale fusion plants in the 2030s. Its magnet and power technologies also have potential applications beyond fusion in advanced industrial and energy systems.
