A trailblazing British nuclear fusion company has raised almost £100 million in funding, fuelling hopes that a pilot plant capable of generating near-limitless clean electricity could be operational within the next decade.
If successful, Tokamak Energy’s technology could revolutionise energy production, providing a near-limitless source of clean power and solidifying Britain’s position at the forefront of global fusion innovation.
Tokamak Energy, based in Oxfordshire, has secured $125 million (£99 million) from investors, including Lingotto, a fund managing the wealth of Italy’s billionaire Agnelli family, chaired by former Conservative Chancellor George Osborne.
This investment brings Tokamak’s total funding to $335 million since its inception in 2009.
Harnessing the Power of the Sun
Tokamak Energy aims to achieve what has eluded scientists for decades: controlling nuclear fusion (the reaction that powers the sun) to produce continuous, low-carbon energy. Unlike traditional nuclear fission, fusion involves forcing hydrogen atoms to fuse under extreme heat and pressure, producing helium as a byproduct and releasing massive amounts of energy.
While fusion was first harnessed in the hydrogen bomb nearly 70 years ago, creating a controlled and sustainable process for energy generation has proven an extraordinary challenge. Fusion requires temperatures 10 to 15 times hotter than the sun, necessitating magnetic fields to contain the reaction, a feat that has defied scientists and engineers for decades.
Breakthrough Technology
Tokamak Energy believes it has made a significant breakthrough with the development of high-temperature superconducting (HTS) magnets, capable of creating magnetic fields a million times stronger than Earth’s. These magnets, combined with advancements in artificial intelligence, may allow engineers to sustain the white-hot plasmas needed for fusion over longer periods.
The company plans to use the latest funding to design a pilot fusion reactor and the superconducting magnet systems required for the process. It has told investors that a fusion pilot plant could be running by 2034.
Chief executive Warrick Matthews expressed confidence in fusion’s potential to transform global energy markets. He said: “We have a target of initial fusion power plants generating power at $70 (£55) per megawatt hour, driving down to $50 per megawatt hour, making us competitive with other baseload power sources like gas.”
Global Race for Fusion Power
Tokamak Energy is one of several global companies racing to commercialise fusion power, with many targeting 2040 for widespread deployment. The company is also involved in the UK’s Step programme, which plans to build a pilot fusion reactor at the former West Burton power station in Nottinghamshire.
The company recently unveiled its reactor design as part of the US Department of Energy’s fusion programme, receiving acclaim at a major international physics conference. The latest funding round includes contributions from Furokawa Electric, which produces metallic strips used in Tokamak’s superconducting magnets, alongside high-profile private investors such as Sir David Harding, Lord Wolfson, and Hans-Peter Wild, owner of Capri-Sun.
Tokamak’s progress underscores the UK’s role as a leader in fusion research and the company’s ambitious vision for fusion offers a glimmer of hope in the quest for sustainable energy.
