Google Partners with Kairos Power for Nuclear Energy in AI Data Centres
In a groundbreaking initiative, Google has signed an agreement with Kairos Power to harness small nuclear reactors to meet the significant energy demands of its artificial intelligence (AI) data centres. The partnership aims to operationalize the first reactor by 2030, with plans to introduce additional reactors by 2035. This collaboration comes amidst a growing trend among tech firms to explore nuclear energy as a sustainable power source for their extensive data operations.

Energy Needs of AI Technologies
The increasing reliance on AI technologies necessitates a substantial amount of electricity. Michael Terrell, Google’s senior director for energy and climate, emphasized the urgency of finding new electricity sources to support these technologies. He stated, “The grid needs new electricity sources to support AI technologies.” The agreement with Kairos Power is positioned as a step towards developing a clean and reliable energy solution that can facilitate the full potential of AI applications.
Jeff Olson, an executive at Kairos Power, highlighted the significance of this deal in advancing the commercialization of advanced nuclear energy. He noted that the partnership will demonstrate the technical and market viability of nuclear solutions that are crucial for decarbonizing power grids.
Regulatory Considerations
Before the project can advance, it must receive approval from the US Nuclear Regulatory Commission and relevant local authorities. This step is critical to ensure compliance with safety and environmental regulations. Kairos Power has already made progress in this area; last year, the company received the first permit in half a century to construct a new type of nuclear reactor in the United States. The company has commenced construction on a demonstration reactor in Tennessee, which is a part of its broader strategy to innovate in nuclear energy technology.

Kairos Power’s focus is on developing smaller nuclear reactors that utilize molten fluoride salt as a coolant, distinguishing them from traditional nuclear plants that typically use water. This innovative approach not only enhances safety but also aims to provide a more efficient and flexible energy solution. As the demand for energy from data centres continues to escalate, such advancements in nuclear technology could play a pivotal role in meeting future energy needs.
The global energy consumption of data centres is projected to more than double by the end of the decade, as noted by Goldman Sachs. As AI technologies proliferate, the energy requirements of these facilities are increasing dramatically. John Moore, an Industry Editor for TechTarget, explained that AI data centres are equipped with specialized hardware that not only consumes significant amounts of power but also generates considerable heat. Therefore, energy-efficient cooling solutions are essential to maintain optimal operating conditions.
Nuclear power presents a virtually carbon-free energy source that can provide continuous electricity supply, making it an increasingly attractive option for tech companies aiming to reduce their carbon footprints. The shift towards nuclear energy aligns with broader climate goals, as highlighted by the United States’ commitment at a United Nations Climate Change Conference last year to triple its nuclear energy capacity by 2050 as part of efforts to transition away from fossil fuels.
Industry Trends
The tech industry’s interest in nuclear energy is reflected in recent developments. For example, Microsoft has reached an agreement to resume operations at the Three Mile Island energy plant, the site of one of the most notorious nuclear accidents in US history in 1979. Similarly, Amazon has announced plans to purchase a nuclear-powered data centre in Pennsylvania, further underscoring the trend of major tech companies exploring nuclear solutions to meet their energy needs.
Challenges and Criticism
Despite the promising aspects of nuclear energy, it is not without challenges. Critics point out that nuclear power carries inherent risks, including the potential for accidents and the generation of long-lasting radioactive waste. These concerns highlight the need for thorough regulatory oversight and continued public discourse regarding the safety and environmental implications of expanding nuclear energy infrastructure.
Google’s partnership with Kairos Power marks a significant step in the tech industry’s ongoing quest for sustainable energy solutions. By integrating nuclear power into its operations, Google aims to address the escalating energy demands of AI technologies while contributing to the decarbonization of power grids. As the industry moves forward with this initiative, it will be essential to navigate regulatory processes, address safety concerns, and foster public acceptance of nuclear energy as a viable solution for the future.
