Nvidia Touts ‘100% Reduction in Water Use’ With New Data Center Design
Nvidia has introduced a closed-loop liquid cooling system for its AI data centers to eliminate on-site water consumption. The design uses a coolant mixture of water and propylene glycol that can operate at temperatures up to 45°C. Critics argue the system does not address water used by power plants and chip manufacturing.

Nvidia Claims 100% Reduction in Data Center Water Use With New Design
confidence 90%Nvidia has introduced a closed-loop liquid cooling system for its AI data centers to eliminate on-site water consumption. The design uses a coolant mixture of water and propylene glycol that can operate at temperatures up to 45°C. Critics argue the system does not address water used by power plants and chip manufacturing.
What's confirmed:
- Nvidia claims its new closed-loop cooling design can cut data center water use by up to 100%.
- The cooling system circulates a liquid coolant composed of three-quarters water and one-quarter propylene glycol.
- The system can run on coolant at temperatures up to 45°C.
- The technology targets on-site water consumption but does not eliminate water used by power plants supplying the grid.
Still unconfirmed:
- The Rubin reference design uses liquid cooling to cut power and nearly eliminate water usage.
- Microsoft signed a deal with Chevron to build a natural gas powered data center in West Texas.
