Nvidia Unveils New Data Center Design to Tackle AI’s Growing Water Consumption Crisis
The rapid expansion of artificial intelligence has intensified public concerns about data centers, including noise pollution, soaring electricity costs, and—most critically—water usage. Residents near data centers have reported issues such as contaminated water, low water pressure, and unauthorized siphoning, putting a fundamental resource under threat. In response, Nvidia announced on Monday that its latest generation of AI servers will rely entirely on liquid cooling, a technology that eliminates the need for water-intensive air-cooling fans.
The new system circulates a liquid coolant made of water and propylene glycol in a closed loop, dissipating heat without drawing in fresh water. “We have eliminated massive amounts of power usage and pretty much all water usage,” said Ali Heydari, Nvidia’s director of data center cooling and infrastructure, in a statement. The coolant can operate at temperatures up to 45°C (113°F), significantly higher than the industry standard of 30°C, which typically requires extensive air conditioning.
This shift comes as the United Nations predicted earlier this month that AI-related water consumption could equal the annual needs of 1.3 billion people by the end of the decade. Nvidia is not alone in pursuing water reduction; in August 2024, Microsoft announced that its new data centers would stop using water for cooling, saving more than 125 million liters per facility annually. However, Nvidia’s approach stands out for pushing the liquid input temperature higher, a move that Andrew A. Chien, a professor of computer science at the University of Chicago, called “super important.” Chien, who directs the CERES Center for Unstoppable Computing, explained that higher cooling temperatures allow heat to be vented to the outside environment without running HVAC units or air conditioners. “The thing that’s exciting about what Nvidia announced is it shows really what’s possible in terms of pushing up this liquid input temperature to 45°C,” he said.
While Chien noted that zero water use is unrealistic, liquid cooling will significantly reduce water demand. The trade-off is cost: these systems are expensive to deploy. Nvidia did not immediately respond to requests for comment on pricing or whether it plans to retrofit existing data centers. However, the company estimates that a 50-megawatt hyperscale facility could save over $4 million per year in cooling-related energy and water costs by transitioning to liquid-cooled infrastructure. “It is a direction that more people should be trying to get to, because it’ll reduce the total power consumption of these large data centers,” Chien added.
