Global data center cooling market heats up
The global data center cooling sector is entering a period of unprecedented growth as operators worldwide race to support AI, high-performance computing (HPC), cloud platforms, and distributed architectures. According to new market data, the industry is expected to grow from $21.86 billion in 2025 to $92.78 billion by 2035.
For eeNews Europe readers, this shift underscores a major transformation in thermal management technologies, component design, and data center operations. As workloads intensify and sustainability regulations tighten, advanced cooling approaches are becoming central to facility planning and long-term competitiveness.
Market growth driven by AI, hyperscale, and high-density computing
According to DC Market Insights, the rapid global build-out of hyperscale data centers remains one of the primary catalysts of market expansion. Cloud providers and AI compute clusters are deploying increasingly dense architectures to support advanced analytics, generative AI, and machine learning. These environments generate significant heat output and require sophisticated cooling to maintain system reliability.
High-performance workloads now frequently exceed the thresholds of traditional air-based cooling, the report indicates. This shift is pushing operators toward direct-to-chip liquid cooling, immersion cooling, and hybrid systems that deliver superior thermal performance while reducing energy consumption. As enterprise outsourcing expands into colocation facilities, demand for scalable and resilient cooling systems continues to rise, particularly in regions investing heavily in 5G networks and digital transformation.
AI and HPC workloads, in particular, are reshaping cooling strategies. Generative AI and advanced modeling applications require racks capable of supporting far higher power densities than legacy installations. As a result, liquid cooling and modular thermal solutions are experiencing accelerating adoption, providing the efficiency and heat management necessary for next-generation compute environments.
Sustainability and regulatory pressure accelerate adoption
Energy efficiency has become a defining factor in data center design and operation across Europe and beyond. Traditional cooling accounts for a substantial share of a facility’s power use, making it a target for operators aiming to reduce carbon footprints and operational expenditure. Regulators worldwide are tightening requirements on emissions, water use, and energy efficiency, prompting companies to prioritize green cooling strategies.
These efforts include integrating renewable energy sources, optimizing airflow management, and expanding liquid-based cooling deployments. As organizations align with sustainability commitments and net-zero initiatives, upgraded cooling systems are becoming essential infrastructure investments rather than optional enhancements.
However, economic and technical barriers persist. Advanced cooling technologies often require significant upfront capital and specialized facility modifications. Legacy data centers, in particular, face challenges integrating modern cooling systems alongside older infrastructures. These cost and complexity issues may slow adoption in developing regions and among smaller operators.
Regional momentum in a global expansion
North America remains the leading market for advanced cooling technology, supported by a high concentration of hyperscale cloud operators and AI investment, the report indicates. Europe is experiencing accelerated growth driven by strict environmental regulations and climate neutrality targets, particularly in the countries of Germany, the Netherlands, Sweden, and the UK.
As global digital infrastructure scales, data center cooling technologies will remain at the forefront of enabling performance, sustainability, and operational resilience—offering a decade of strong opportunity for suppliers, innovators, and engineering teams worldwide.
