About the company:

The world needs a clean and reliable source of base-load energy to develop sustainably into the future. That’s what Tokamak Energy is striving to achieve.

Tokamak Energy is a private company accelerating the development of fusion power.

Fusion – the energy source that powers the sun – is globally accepted as the best way to generate plentiful, safe, secure and clean energy. The tokamak is the most heavily researched and best understood of all the different paths to fusion.

It is now acknowledged that the spherical tokamak design offers the smallest and most cost-effective solution. This is our solution. Yet there are many complex engineering challenges that need to be overcome for demonstration and commercialisation of this technology.

Our team of world-class fusion scientists and magnet engineers is tackling these challenges to develop efficient and affordable fusion power. Our unique approach is centred on rapid innovation using the latest materials and technology – but building on decades of scientific research and experience. This strategy gives us – and the world – a faster way to fusion.

Once fusion electricity is achieved, our scalable technology could be rolled out across the world as a solution to one of humanity’s greatest challenges: clean and sustainable energy for all.

What if there was a limitless, safe, clean, low-cost energy source, providing much needed global energy security?  What if that energy source could also help reduce climate change?  We believe that’s fusion energy.  Tokamak Energy is a leading global commercial fusion energy company based near Oxford, UK.  We have an unrivalled track record designing and operating spherical tokamaks; the optimal route to commercial fusion energy.  

In addition to fusion energy, Tokamak Energy is recognised as the leader in High Temperature Superconductor (HTS) magnet, design, numerical modelling, and prototyping.  Our dedicated HTS magnet team, in collaboration with key manufacturing partners, is focussed on becoming the leading supplier of HTS magnets to multiple markets.   

The company, founded in 2009 as a spin-off from the UK’s Culham Centre for Fusion Energy, currently 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.  The company has 70 families of patent applications and has raised $250 million, comprising $200m from private investors and $50m from the UK and US governments.  Our US subsidiary, Tokamak Energy Inc, was established in 2019.  

Come and be a part of a dynamic and innovative team who are striving to provide a solution to one of humanity’s greatest challenges: clean and sustainable energy for all.
