A group of major energy users have signed a pledge to support tripling global nuclear power capacity by 2050. Nuclear power is seeing a resurgence in popularity thanks in part to significant growth in power demand due to AI.

Google recently signed a deal to purchase nuclear energy from multiple SMRs from Kairos Power. Kairos expects to deploy the first SMR by 2030, followed by further deployments through to 2035. In total, the US-only deal covers up to 500MW across six to seven reactors.

The pledge is nonbinding, but highlights the growing support for expanding nuclear power among leading industries, finance and governments.
