Type One Energy and the Tennessee Valley Authority (TVA) have entered a cooperative agreement to develop plans for a potential fusion power plant project using Type One Energy’s stellarator fusion power technology in the Tennessee Valley region of the US.

The project, named Infinity Two, is aimed at providing a complementary source of base load electrical generation by the mid-2030s.

Infinity Two, a 350MW fusion pilot power plant, will utilise the infrastructure of a retired TVA fossil fuel power plant as well as using greenfield sites.

The initiative is part of the broader Project Infinity which began in early 2024 and involves TVA, the US Department of Energy’s Oak Ridge National Laboratory (ORNL) and the state of Tennessee.

The project initially focused on deploying the Infinity One stellarator prototype at TVA’s Bull Run power plant and now moves towards the commercialisation of fusion energy.

The cooperative agreement will see TVA and Type One Energy collaborate on siting studies, environmental reviews, licensing and the development of project plans and financing from diverse sources.

TVA innovation and research vice-president Joe Hoagland stated: “Unleashing America’s energy potential will take all forms of generation including fusion.

“Energy security is national security, and we are focused on developing a technology, supply chain and delivery model to build an industry that can power America and the world.”

The collaboration also extends to TVA’s power service shops (PSS) in Alabama, which will support Type One Energy’s supply chain for stellarator fusion plants.

This will aid in the modular manufacturing of Infinity Two and enable TVA to tap into the global scaling of fusion energy.

This agreement also complements Type One Energy’s recent technology licensing and manufacturing agreement with Commonwealth Fusion Systems, further demonstrating the company’s commitment to advancing fusion energy technology.

Type One Energy CEO Christofer Mowry added: “We are fortunate indeed to work together with an energy company like TVA. TVA brings us best-in-class power plant operations, maintenance, engineering, licensing and even project planning and construction capabilities – all skills critical to success that we now don’t need to try and recreate.

“Instead, we can focus on completing the design of Infinity Two and testing it with the Infinity One prototype in TVA’s Bull Run plant. The ability for us to focus on developing and delivering the core stellarator technology materially de-risks our path to fusion power plant commercialisation.”
