Google has announced its plan to use small nuclear reactors to power its AI data centres, partnering with Kairos Power to develop this new energy source. The aim is to bring the first reactor online by the end of this decade, with more expected by 2035. These reactors will use molten salt as a coolant instead of water, providing a more efficient and sustainable energy solution.
The growing demand for AI technologies has increased the need for stable, reliable, and clean energy. Nuclear power, which is carbon-free and provides constant electricity, fits perfectly with tech companies’ goals of reducing their carbon footprint. Michael Terrell, Senior Director for Energy at Google, highlighted that these new energy sources will help unlock the full potential of AI while maintaining sustainability.
Kairos Power, known for its innovative molten fluoride salt reactor technology, offers smaller, more flexible reactors that operate more efficiently than traditional nuclear plants. These reactors have the advantage of being able to provide continuous power, unlike renewable energy sources such as wind or solar, which are weather-dependent. Additionally, small modular reactors like those developed by Kairos are seen as the future of nuclear energy because they offer scalability and reduced construction costs.
The regulatory commission will decide
Despite the enthusiasm from both companies, however, the plans are subject to strict regulatory processes. The agreement must be approved by both the US Nuclear Regulatory Commission and local agencies in the areas where reactor construction is planned. Approval processes can take months, if not years, and will require strict safety and environmental standards.
Other tech giants do it like Google
Other tech giants like Amazon and Microsoft are also looking into nuclear energy to power their data centres. For instance, Amazon has plans to acquire a nuclear-powered data centre in Pennsylvania. Microsoft has also taken steps to restart the Three Mile Island nuclear plant.
With data centre energy consumption expected to double by 2030, nuclear energy’s potential to provide clean, round-the-clock power makes it an increasingly attractive option for tech companies looking to balance innovation with environmental responsibility. While nuclear power remains controversial due to the production of radioactive waste and safety concerns, its virtually carbon-free output makes it a key contender in the tech industry’s race to minimize emissions.
Google’s deal with Kairos Power shows a clear trend of tech companies moving toward innovative energy solutions to power the ever-growing demands of AI and digital infrastructure.
