As digitalisation and artificial intelligence (AI) drive unprecedented growth in data centre operations, the need for effective cooling solutions has become critical. ABI Research forecasts that the global number of data centres will more than double from 10,978 in 2023 to over 21,000 by 2030. This surge is expected to push energy consumption for cooling alone from 300 terawatt-hours (TWh) in 2023 to a staggering threefold increase by 2030, equating to a 15% compound annual growth rate (CAGR).
The rising energy demands are underscored by recent regulatory challenges, such as the rejection of Google’s data centre proposal in Dublin, which highlights the urgent necessity for sustainable energy sources. Rithika Thomas, senior analyst for Sustainable Technologies at ABI Research, says: “Cooling load alone accounts for up to 40% of a data centre’s energy consumption. Effective cooling strategies demand a holistic, technology-agnostic approach to optimise Power Usage Effectiveness (PUE), Water Usage Effectiveness (WUE), and thermal management.”
With pressures mounting from regulatory frameworks such as the Energy Efficiency Directive (EED) and the European Code of Conduct for Data Centers, operators are compelled to adopt responsible computing practices. Thomas believes, “A ‘one size fits all’ approach fails to factor in the impact of size, location, infrastructure needs, cost, local regulations, and workloads, all vital to design an efficient cooling solution.”
To navigate these challenges, data centre operators are increasingly implementing hybrid and modular cooling technologies. Partnerships with companies like Carrier Global Corporation, Daikin, and Schneider Electric are facilitating innovations that integrate liquid and immersion cooling solutions, enhancing efficiency and reducing energy consumption.
Today’s advanced cooling systems leverage AI-driven monitoring and predictive maintenance, ensuring optimal performance while extending the lifespan of IT equipment. This shift not only addresses immediate cooling needs but also aligns with long-term sustainability goals, as operators face growing scrutiny over their environmental impact and carbon footprints.
As data centres brace for a future of tripled energy demands, the adoption of innovative cooling solutions and renewable energy sources will be pivotal. Operators must prioritise efficient cooling strategies to mitigate costs and environmental impact while ensuring reliable service amidst the rising tide of digitalisation and AI advancements.
