- Nvidia announced at London Climate Week that its latest AI system can be fully cooled by a recirculated water-and-propylene-glycol liquid that operates at 113°F, letting facilities rely less on energy- and water-intensive chilling equipment — or drop it altogether.
- Josh Parker, Nvidia's chief sustainability officer, said in an interview ahead of the trip that 'The water consumption challenge for data centers is largely solved.'
- Microsoft VP of data center engineering Steve Solomon, asked about the potential before learning of the announcement, called it 'a big deal for everybody' and said it could eliminate mechanical chillers in most climates most of the time, even in hot places like Arizona.
- The announcement follows Google and Amazon defending their data center water practices amid growing local opposition to AI infrastructure, as tech companies increasingly argue efficiency gains will blunt AI's environmental footprint.
- Nvidia's technology would take years to spread across the industry, and existing data centers will keep running older cooling systems; Nvidia declined to disclose the costs of the new system.
- Parker acknowledged the efficiency gains are meant to support more AI growth, writing that 'AI workloads are not getting lighter' and warning that energy demand would continue rising alongside demand.
Why it matters: If Nvidia's liquid-cooling approach spreads, data center operators could eliminate mechanical chillers and the energy and water they consume — but Parker himself frames the savings as fuel for more AI buildout, not a smaller footprint. Existing facilities will keep running older systems for years, and electricity generation for AI remains a separate water concern the technology does not address.
