Enaxiom says HydroCool helps AI data centers regenerate and reuse water

• Enaxiom calls HydroCool the first regenerative cooling system, built to go beyond cutting water use 1.
• Its patented closed loop prevents evaporative loss, a persistent problem in standard data center cooling that can use millions of litres each day 2.
• The setup uses wastewater for evaporation and creates freshwater as a by-product, said Enaxiom 2.
• HydroCool works with dense AI cooling approaches such as direct-to-chip, which cools processors directly, and immersion cooling, which submerges hardware in liquid 2.

Water-saving cooling could shape how cities plan infrastructure

• Data centers can strain local water supplies. Loudoun County, Virginia, used about 900 million gallons in 2023 for cooling alone 3.
• Cutting potable water use and recovering water onsite could help these facilities fit more easily into civic infrastructure, in Enaxiom’s view 4.
• Recovered water could go to vertical farms that grow crops indoors in stacked layers. It could also provide thermal input for green hydrogen production, which uses cleaner energy sources to make hydrogen 4.
• Gartner, a technology research and advisory firm, forecasts a 160% jump in electricity demand from AI-enabled data centers. By 2027, grid limits could constrain 40% of them 2.
