Microsoft Plans to Launch Water-Free Cooling in New Data Centers by 2027
Microsoft has introduced an innovative data center design that eliminates the need for water to cool its servers and chips, marking a significant step toward sustainability in the face of growing concerns about the environmental impact of artificial intelligence (AI). The new water-free cooling system, rolled out in August 2024, uses a closed-loop system that circulates water between servers and chillers to remove heat, without the need for constant water replenishment. This system aims to drastically reduce the environmental footprint of data centers that power popular AI models, including OpenAI’s ChatGPT.
How Microsoft’s Water-Free System Works
The design achieves precise temperature control by adopting chip-level cooling solutions, which prevent water evaporation. Microsoft stated that while the system does not eliminate water use entirely—necessary for facilities like toilets and kitchens—it will save over 125 million liters of water per year for each data center. The company emphasized that this innovation will significantly reduce the amount of water required for cooling, a resource-intensive process in traditional data centers.
AI and Crypto Mining’s Water and Power Consumption
The need for sustainable data center technologies comes as AI and crypto mining operations are under scrutiny for their significant water and power usage. For example, a recent study revealed that the water required to cool a Bitcoin transaction could fill an entire household pool. Similarly, reports show that ChatGPT consumes half a liter of water to generate 100 words, further highlighting the importance of sustainable solutions.
Microsoft’s Future Data Centers to Use Water-Free Cooling
Microsoft confirmed that its existing data centers will continue using air and water-based cooling systems, but its new projects in Arizona and Wisconsin are set to pilot the water-free design in 2026. Moreover, the company plans to adopt the zero-water evaporation system as the primary cooling solution for new data centers expected to go live by late 2027.
As Microsoft continues to expand its AI capabilities, its Azure business, which saw a 33% year-on-year growth by September 30, 2024, will be a key focus for future investment, though returns are expected to take time.
This innovative leap in sustainable data center technology is part of Microsoft’s broader effort to mitigate the environmental effects of the AI revolution.
