Google inks nuclear deal for next-generation reactors

Google plans to buy electricity from next-generation nuclear reactors. It announced the deal yesterday, which it says is the world’s first corporate agreement to purchase electricity from advanced small modular reactors (SMRs) that are still under development.

Google inked the deal with engineering company Kairos Power, which plans to get its first SMR up and running by 2030. Google agreed to purchase electricity from “multiple” reactors that would get built through 2035.

Google needs a lot more clean energy to meet its climate goals while pursuing its AI ambitions. New nuclear technologies are still unproven at scale, but the hope is that they can provide carbon pollution-free electricity while solving some of the problems that come with traditional nuclear power plants.

“Obviously, the trajectory of AI investments has added to the scale of the task needed,” CEO Sundar Pichai said in an interview with Nikkei earlier this month. “We are now looking at additional investments, be it solar, and evaluating technologies like small modular nuclear reactors, etc.”

What sets Google apart with this deal is that it’s turning to next-generation reactors rather than traditional power nuclear power plants. SMRs are roughly one-tenth to one-quarter the size in comparison. Their size and modular design are supposed to make them cheaper and easier to build and site than their larger predecessors. And unlike solar and wind energy that fluctuate with the weather and time of day, nuclear power plants can generate electricity around the clock. Even with new reactor designs, however, there are still environmental and health concerns when it comes to mining and enriching uranium for reactors and storing radioactive waste.

The US Nuclear Regulatory Commission certified a design for a small modular reactor for the first time last year. Experts tell The Verge they expect the first SMRs to connect to US power grids in the early 2030s at the earliest, and Big Tech’s interest in nuclear energy seems to be giving the industry a boost.

Google says its deal with Kairos Power would eventually help bring up to 500 MW of carbon-free energy to power grids in the US. Kairos broke ground on its first demonstration reactor in Tennessee in July.

“Having an agreement for multiple deployments is important to accelerate the commercialization of advanced nuclear energy by demonstrating the technical and market viability,” Jeff Olson, Kairos Power vice president of business development & finance, said in a press release.
