Google’s nuclear energy partnership explained

Google has taken a major step toward its clean energy future by signing an agreement to support a next-generation nuclear reactor in Tennessee. This initiative, in collaboration with the Tennessee Valley Authority, will provide electricity from an advanced Kairos Power reactor to the grid powering Google’s data centers in Tennessee and Alabama. Expected to come online by 2030, the project represents one of the most significant advancements in nuclear energy development in the United States in decades.

Why next-generation nuclear energy matters

Unlike older nuclear plants that rely on traditional water-cooled technology, Kairos Power is introducing a new design that uses molten fluoride salt as a coolant. This approach allows the reactor to operate at low pressure, reducing infrastructure costs while improving safety and efficiency. With growing electricity demand from artificial intelligence and cloud services, next-generation nuclear energy could play a critical role in meeting energy needs while cutting carbon emissions.

Google’s role in accelerating nuclear innovation

By committing to purchase power from Kairos Power’s Hermes 2 demonstration reactor, Google is helping drive investment into advanced nuclear technology. This is the first agreement of its kind involving a U.S. utility and such an advanced design. For Oak Ridge, Tennessee—once central to the Manhattan Project—this marks a transformation into a hub of modern nuclear innovation. The project also builds on previous milestones, including the groundbreaking of the Hermes demonstration plant last year.

The future of nuclear energy and clean power

If successful, this partnership could mark the beginning of a new era for nuclear power in the U.S. The technology promises to provide a stable, carbon-free energy source that complements renewable options like wind and solar. For Google, it’s not only about powering data centers but also about leading the way in sustainable energy innovation. The project demonstrates how advanced nuclear technology can help meet rising electricity demand while advancing global climate goals.
