General Fusion, a Canadian energy company backed by Amazon CEO Jeff Bezos' investment firm, Bezos Expeditions, has announced plans to build and operate a nuclear fusion plant in the United Kingdom.

General Fusion will enter into a long-term lease with the U.K. Atomic Energy Authority's Culham campus, home of the country's national fusion research program and the largest fusion experiment in the world, Joint European Torus.

General Fusion, a Canadian clean energy company backed by Amazon CEO Jeff Bezos' investment firm, Bezos Expeditions, has announced plans to build and operate a nuclear fusion plant in the United Kingdom.

The new facility, dubbed the Fusion Demonstration Plant, will verify whether the company's proprietary magnetized target fusion (MTF) technology can create fusion conditions in a practical and cost-effective manner and "refine the economics of fusion energy production," which will then lead to the subsequent design of a commercial fusion pilot plant.

The Fusion Demonstration Plant, which has an estimated cost of $400 million, is expected to begin construction in 2022. The company expects the plant to be fully operational as early as 2025.

U.K. Science Minister Amanda Solloway said the plant will be a "huge boost" to the country's plans to develop a fusion industry.

"I’m thrilled that Culham will be home to such a cutting-edge and potentially transformative project," Sollway added. "Fusion energy has great potential as a source of limitless, low-carbon energy, and today’s announcement is a clear vote of confidence in the region and the UK’s status as a global science superpower."

The plant will expand General Fusion's presence into Europe and will broaden its network of government, institutional and industrial partners.

"This is incredibly exciting news for not only General Fusion, but also the global effort to develop practical fusion energy," General Fusion CEO Christofer Mowry said.

A General Fusion spokesperson told FOX Business that while Bezos Expeditions is an investor, they do not play an operational role in the company. General Fusion has raised a total of approximately $300 million from its investors to date.

In addition to Bezos Expeditions, General Fusion's investors include Chrysalix Venture Capital, Braemar Energy Ventures, Set Ventures, Malaysian sovereign wealth fund Khazanah Nasional, Cenovus Energy, BDC Venture Capital, Pender Ventures, the Entrepreneurs Fund and Sustainable Development Technology Canada. General Fusion's collaborators include Microsoft, McGill University, Princeton Plasma Physics Laboratory, Hatch and Queen Mary University of London.

General Fusion's technology uses a series of synchronized pistons to compress a chamber of liquid metal, which is then injected with hydrogen plasma. The plasma is then heated at 150 million degrees Celsius – 10 times hotter than the sun's core – to create large quantities of carbon-free energy with no atomic waste. The heat is then transferred into the metal, which can be channeled through turbines to produce power.

According to General Fusion, just 1 kilogram of fusion fuel can power 10,000 homes for one year and replace 55,000 barrels of oil, 6 million kilograms of natural gas, or 10 million kilograms of coal. General Fusion’s technology is expected to produce about 115 megawatts of fusion power.

In addition, 35 countries are collaborating to build the International Thermonuclear Experimental Reactor (ITER) in southern France, which is aiming to produce about 500 megawatts of fusion power as early as 2035.
