About us
Our U.S. subsidiary, Tokamak Energy Inc., was established in 2019, building on long-standing relationships with U.S. research, industry and government partners.
We are proud to be part of the U.S. Department of Energy (DOE)’s Milestone Based Fusion Development Program, which supports efforts by private fusion companies to build commercial fusion pilot plants in the United States.
Recently, we announced a partnership with the U.S. DOE and the UK Department of Energy Security and Net Zero (DESNZ) to advance crucial technologies for fusion through a $52 million program utilizing our high-field ST40 spherical tokamak.
As the only private company with over a decade of experience in designing, building, and operating tokamaks, we collaborate closely with U.S. universities and National Laboratories, including Oak Ridge, Sandia, Princeton, Los Alamos, and the University of Illinois. We’ve received eight awards from the U.S. Innovation Network for Fusion Energy (INFUSE) program, enabling us to contribute to the advancement of U.S. fusion energy technology.
A bold decadal vision
The U.S. DOE’s $46 million Milestone Based Fusion Development Program was created to accelerate the viability of commercial fusion energy in partnership with the private sector.
As one of eight private companies selected for the program, we are designing a spherical tokamak-based fusion pilot plant with the aim of demonstrating net energy output in the 2030s, partnering with U.S. universities and national laboratories to address and overcome key technological challenges.
Our pilot plant will be capable of generating 800 megawatts (MW) of fusion power and 85MW of net electricity, enough to power and heat more than 70,000 American homes. It will feature a set of next-generation high temperature superconducting (HTS) magnets to confine and control the deuterium and tritium hydrogen plasma.

“Fusion power represents the promise of a clean and energy-secure future. Tokamak Energy’s world-leading technology will grant the U.S. energy independence and revolutionise energy-intensive industries. We are delighted to be participating in the DOE Milestone Driven Fusion Development Program – a 10-year race to deliver a prototype fusion power plant.”
Michael Ginsberg, President, Tokamak Energy Inc.
Case study – University of Illinois
We have partnered with the Grainger College of Engineering at the University of Illinois Urbana-Champaign to address one of the key challenges for the fusion pilot plant we are designing as part of the U.S. DOE’s Milestone-Based Fusion Development Program.
Experts from both teams will collaborate at Illinois Grainger Engineering’s state-of-the-art research facilities to conduct essential research on liquid metal plasma-facing components. This focus is crucial for next-generation fusion energy devices, with the potential to enhance plasma performance and protect solid first wall materials from the extreme conditions inside a fusion plant.
“Our partnership with Tokamak Energy represents an exciting frontier in fusion research, leveraging the university’s strengths in scientific discovery to solve one of the greatest energy challenges of our time. Together, we are not only advancing fusion science but also preparing the next generation of fusion experts.”

ST40 research and upgrade program
We recently announced a partnership with the U.S. DOE and UK DESNZ to advance critical technologies for future fusion power plants through a $52 million upgrade program for our record-breaking ST40 spherical tokamak.
The upgrade will focus on using lithium-coated plasma-facing components (PFCs) to enhance plasma performance, building on pioneering work by PPPL and others. Lithium is recognized as a crucial element in fusion power plants, both for PFCs and the ‘breeding blankets’ that will surround the plasma to capture energy and produce tritium fuel.
Cooperation between the U.S. and UK governments builds on the strategic fusion partnership announced in 2023, and will enable collaborators at universities and national laboratories in both countries to benefit from cutting-edge research on ST40.
Since 2019, ST40 research has been conducted under a pioneering public-private partnership established between Tokamak Energy and U.S. researchers from Princeton Plasma Physics Laboratory (PPPL), Oak Ridge National Laboratory (ORNL), and the University of Washington.
“We’re eager to see this new capability on ST40. What excites me most is the possibility of deploying our university and national lab scientists to leverage this new capability through our Private Facility Research program. It’s these publicly supported scientists, collaborating with their colleagues at private facilities, who drive the major advances needed in this field to support a competitive U.S. fusion power industry.”
