Tokamak Energy is pursuing the global deployment of commercial fusion through the combined development of spherical tokamaks with High Temperature Superconductor (HTS) magnets. It is the only private fusion company to have more than 10 years’ experience of designing, building and operating tokamaks.
The company, founded in 2009 as a spin-off from UK Atomic Energy Authority, employs a growing team of over 250 people with experts from the UK and around the world. It combines world leading scientific, engineering, industrial and commercial capabilities and has more than 75 families of patent applications. Its U.S. subsidiary, Tokamak Energy Inc, was established in 2019.
Magnetic confinement in tokamaks is the most mature concept. Tokamak Energy’s spherical design is more efficient than the conventional shape, with lower capital investment, operating costs and a smaller footprint. Enabled by its magnet technology, the company believes this is the optimal approach both scientifically and commercially, delivering the lowest levelized cost of energy. Tokamak Energy has pioneered these technologies since 2012, long before their importance was widely recognised, and is on a mission to deliver clean, secure and affordable fusion in the 2030s.
Tokamak Energy operates high field spherical tokamak ST40 at Milton Park, Oxfordshire.
