Tech Giants Bet on Mini-Reactors to Power AI Boom

The relentless growth of artificial intelligence is creating an energy crisis of its own. To feed the staggering power demands of massive data centers, the technology industry is turning to a new, compact solution: small modular reactors, or SMRs.

These next-generation nuclear units represent a stark departure from the traditional, colossal power plants that can take a decade to build and require enormous upfront investment. Instead, SMRs are designed to be leaner, safer, and faster to deploy.

“These kinds of reactors have a small footprint and upgraded safety systems, and can be deployed in nearby industrial areas, including data centre campuses,” explained Rafael Mariano Grossi, Director General of the International Atomic Energy Agency (IAEA). He highlighted a key advantage for tech companies, noting they “don’t have to worry about regional grid supply constraints or transmission losses. This will be a decisive advantage in areas where grid upgrades are slow, and interconnection queues are long.”

While SMR technology is still advancing from research into real-world application, momentum is building. The IAEA is actively collaborating with global regulators and the nuclear industry to clear the path for widespread deployment. The goal is to see these smaller units operating in large numbers to meet surging electricity demands.

Google’s Nuclear Energy Pact

In a landmark move, Google has signed a pioneering agreement to purchase nuclear energy generated from multiple small modular reactor, a first-of-its-kind deal globally. If development stays on track, the reactors could be supplying clean power to Google’s operations by 2030.

Not content with terrestrial solutions alone, Google is also gazing skyward. The company is investigating the potential of space-based solar networks, which would use unfiltered solar energy in orbit to power large-scale machine learning operations. To test the concept, two prototype satellites are scheduled for launch in early 2027, where their radiation tolerance and data processing capabilities will be put to the test.

From restarting shuttered plants to constructing giant new reactors, and from betting on miniature atomic units to capturing sunlight in space, the strategies vary wildly. Yet energy experts observe that all these paths converge on the same inevitable conclusion: building a future-proof energy system capable of supporting advanced civilization will require a foundation built largely upon nuclear power.
