Google has made a groundbreaking move by signing what it calls the world’s first corporate deal to buy nuclear energy from multiple small modular reactors (SMRs). These reactors will be developed by Kairos Power and are a key part of Google’s strategy to create a diverse range of advanced clean energy technologies to power its global datacenters and offices.
SMRs are smaller and designed in a modular way, allowing for faster construction compared to traditional nuclear plants. Google noted that their compact size means they can be installed in a wider variety of locations. Michael Terrell, Google’s senior director of energy and climate, explained in a blog post that this approach will work alongside renewable sources like solar and wind. It’s all about helping Google achieve its goal of 24/7 carbon-free energy and reaching net-zero emissions.
Terrell emphasized that using SMRs will supply the necessary electricity for Google’s datacenter servers, supporting the AI technologies that fuel significant scientific breakthroughs, enhance business services, and contribute to economic growth. He believes this agreement paves the way for cleaner and more reliable energy solutions that can maximize AI’s potential for everyone.
He pointed out that the next-gen nuclear reactors present a solid pathway for quick deployment with their straightforward designs and strong safety features. The smaller, modular design not only shortens construction times but also allows for installation in more locations, contributing to greater predictability in project delivery.
Moreover, Google’s investment in advanced nuclear technology is expected to bring economic benefits to communities across the U.S. Kairos Power’s technology employs a molten-salt cooling system and a ceramic, pebble-type fuel to effectively generate power using a steam turbine. Terrell described this system as “passively safe,” which means it operates at low pressure. That design simplicity makes it a more affordable option for nuclear energy.
Kairos Power plans to take an iterative approach, conducting multiple hardware demonstrations before launching its first commercial plant. This method should enable them to enhance efficiency and speed up reactor deployments while ensuring cost certainty.
By procuring electricity from several reactors—often referred to as an “orderbook” of reactors—Google aims to promote faster deployment and lower costs, bringing Kairos Power’s innovative technology to market sooner. This strategy is crucial for expanding the benefits of advanced technologies to more communities and builds on Google’s ongoing efforts in the energy sector.
