Kairos Power has just broken ground on its Hermes 2 reactor in Tennessee — a next-gen (Gen IV) nuclear plant that will supply up to 50MW of clean power to the grid, directly supporting Google’s data centres.

This isn’t a pilot concept. It’s the first power-producing advanced reactor of its kind to receive regulatory approval and move into construction, marking a major step from promise to deployment.

AI and cloud infrastructure are pushing electricity demand to new highs — and hyperscalers need reliable, 24/7 low-carbon power that renewables alone can’t guarantee.

What’s changing:

• Tech companies are now directly backing nuclear projects
• Small modular / advanced reactors are moving from R&D to real assets
• Energy strategy is becoming core to data centre strategy

Bottom line:
Nuclear is entering the data centre stack!
