Google partners with Kairos Power to deploy small nuclear reactors for data centres by 2030, signalling a shift in big tech’s approach to sustainable energy.
Google’s recent announcement to power its data centres with nuclear power isn’t just another tech innovation—it’s a glimpse into the future of big tech’s energy strategy. The Silicon Valley giant has partnered with Kairos Power to deploy small modular reactors (SMRs) by 2030, marking a dramatic shift from traditional renewable sources to nuclear power.
This bold move by Google is not an isolated incident. It’s part of a growing trend among significant technology firms looking to nuclear energy to solve their skyrocketing power demands. As artificial intelligence (AI) and data-intensive operations consume more electricity, the tech industry is reevaluating its approach to sustainable energy.
Google’s agreement with California-based Kairos Power outlines plans for deploying SMRs to power data centres, with additional reactor deployments scheduled through 2035. This long-term commitment to nuclear energy marks a departure from the traditional renewable sources that have dominated tech companies’ sustainability efforts in recent years.
The move surprises industry observers tracking the rising energy demands of artificial intelligence (AI) and other data-intensive operations. As AI technologies become more sophisticated and widespread, the energy requirements for training and running these systems have escalated.
While clean, traditional renewable sources like solar and wind often struggle to provide the consistent, high-capacity power needed for these energy-hungry applications. However, Google is not alone in its nuclear ambitions. Microsoft, another tech behemoth, has also explored nuclear options for its data centres.
In 2022, Microsoft partnered with TerraPower, a nuclear innovation company, to develop small nuclear reactors for data centre applications. The company aims to have these reactors operational by the early 2030s. Amazon, while not directly investing in nuclear power, has been indirectly supporting the industry.
In 2023, the e-commerce giant signed an agreement with X-energy to potentially purchase power from a new small modular reactor project in Washington state. This move aligns with Amazon’s commitment to powering its operations with 100% renewable energy by 2025.
The trend extends beyond US borders. In France, energy company EDF has talked with several tech firms about powering data centres with small modular reactors. While specific companies haven’t been named, this development underscores the global nature of this shift towards nuclear power in the tech industry.
What are small modular reactors?
Small modular reactors, the technology at the heart of this trend, offer several advantages over traditional nuclear plants. These include smaller physical footprints, enhanced safety features, and the ability to scale power generation flexibly. However, it’s important to note that SMR technology is still in its early stages of commercial deployment, and its long-term viability and safety record are yet to be fully established.
The tech industry’s pivot to nuclear power is not without controversy. While nuclear energy offers a low-carbon alternative to fossil fuels, concerns about safety, waste management, and high initial costs persist. Critics argue that the focus should remain on improving and expanding existing renewable technologies rather than investing in nuclear power.
However, proponents of nuclear energy in the tech sector argue that the baseload power provided by nuclear plants is essential for meeting the industry’s growing energy demands, particularly as AI and other data-intensive technologies become more prevalent. They contend that a diverse energy mix, including nuclear, will be crucial for achieving true sustainability in the face of rising energy consumption.
The implications of this trend are far-reaching. If successful, the marriage of nuclear power and data centres could significantly reduce the tech industry’s carbon footprint while providing the reliable, high-capacity energy needed to fuel innovation. It could also revitalize the nuclear industry, spurring further advancements in SMR technology and other nuclear innovations.
However, this shift also raises important questions about the future of energy infrastructure and the role of private companies in its development. As tech giants increasingly invest in their power generation capabilities, it could reshape the traditional utility landscape and potentially impact energy access and pricing for other sectors and consumers.
Ultimately, as Google, Microsoft, and other tech leaders continue to explore nuclear options, it’s clear that the industry is at a crossroads. While the outcome remains uncertain, one thing is clear: the race to secure clean, reliable energy for the AI-powered future is well and truly underway, with nuclear power emerging as a critical contender in this high-stakes game.
