World’s first 400 MW commercial fusion power plant could power over 200,000 US homes

The US has set its sights on developing the world’s first commercial fusion power plant, which could deliver up to 400 megawatts (MW) of electricity to more than 200,000 US households annually.

The so-called Project Infinity will include the Infinity One stellarator engineering prototype as well as Infinity Two, a planned commercial fusion plant capable of generating 400 megawatts (MW) of electricity.

Type One Energy, a fusion energy company based in Knoxville, is developing both facilities at the Tennessee Valley Authority’s (TVA) Bull Run site. The company has reportedly completed a USD 200 million Series B financing round to support the development of its fusion technology for Project Infinity.

“The Series B financing enables us to remain focused on advancing our stellarator technology and Project Infinity design activities, while working with experienced industrial partners to deliver the first commercial fusion power plant at TVA’s Bull Run site,” Christofer Mowry, Type One Energy CEO, said.

Bringing fusion to the grid

Nuclear fusion is the process of combining two light atomic nuclei into a heavier nucleus, which releases a massive amount of energy. However, one of its biggest challenges is maintaining the extremely hot plasma needed for fusion reactions while keeping it away from the walls of the reactor.

Stellarators use complex magnetic fields (CMFs) to confine this plasma. Despite being studied for decades, the technology has yet to generate electricity on a commercial scale.

But according to Type One Energy, the greatest challenges for stellarator fusion involve engineering and large-scale deployment rather than plasma physics. To address them, the FusionDirect technology combines advanced manufacturing, computational physics, and high-field superconducting magnets.

The company aims to use Infinity One as an engineering prototype to design and test systems needed for a commercial plant. Meanwhile, Infinity Two will take the next step by producing 400 MW of commercial fusion power at Bull Run. Based on the Tennessee Valley Authority’s (TVA) benchmark 400 MW of electricity would be enough to power roughly 226,000 US homes.

Pushing fusion forward

For the initiative, Type One Energy plans to rely on existing energy and industrial firms rather than build everything itself. This partner-based model could reduce development costs and risks and shorten the time needed to bring fusion plants online.

According to the company, it could also allow several commercial fusion projects to be designed simultaneously instead of waiting for one facility to be completed before beginning another. The latest financing round was co-led by Breakthrough Energy Ventures and Clutterbuck Capital, with participation from Lowercarbon Capital, Siemens Energy Ventures, SiteGround Capital, and other investors.

Carmichael Roberts of Breakthrough Energy Ventures said fusion’s main challenge is deploying the technology instead of making new scientific discoveries. “We are pleased to deepen our support as the company advances Project Infinity and its international partnerships,” Roberts continued.

Type One Energy is also pursuing another commercial deployment through the UK Infinity Fusion Consortium. The company is working with Tokamak Energy, AECOM, Sheffield Forgemasters, and Barclays on the effort.

“Fusion has the potential to become an important source of reliable, low-carbon energy at scale,” Enrique Gonzalez Zanetich, Siemens Energy Ventures partner, shared in press release. This investment strengthens our position in the fusion field as we continue to explore the technologies and collaborations that can help advance commercialization.”
