Tokamak Energy’s new advanced fusion prototype to be built in Oxfordshire
A new fusion energy advanced prototype with power plant-relevant magnet technology will be built by Tokamak Energy at United Kingdom Atomic Energy Authority’s (UKAEA) Culham Campus, near Oxford.
Tokamak Energy’s compact spherical tokamak, ST80-HTS, will demonstrate multiple technologies required for the delivery of clean, sustainable fusion energy. This includes a complete set of cutting-edge high temperature superconducting (HTS) magnets to confine and control the hydrogen fuel, which becomes plasma many times hotter than the sun. Constructing the new purpose-built facility at UKAEA’s Culham Campus, part of the thriving UK Fusion Cluster, provides the company with access to leading science and engineering capabilities, including knowledge and experience in designing, constructing and operating the record-breaking Joint European Torus.
It further builds on the framework agreement signed by Tokamak Energy and UKAEA in October 2022 to enable closer collaboration to develop spherical tokamaks as a route to commercial fusion energy. Designs for the facility are underway in partnership with construction consultants McBains, with build completion planned for 2026.
Chris Kelsall, Tokamak Energy CEO, said: “Today’s exciting announcement is a major step forward on our mission to demonstrate grid-ready fusion energy by the early 2030s. Our next device, ST80-HTS, aims to validate key engineering solutions needed to make commercial fusion a reality and will showcase our world-class magnet technology at scale. It’s clear public and private partnerships of this nature will be a crucial catalyst for fusion to deliver global energy security and mitigate climate change.”
