The global data centre refrigerant market is on the brink of change as it edges towards its substantial growth trajectory. With values reaching USD 633 million in 2025, projections indicate a potential surge to USD 1.62 billion by 2035. This growth is primarily propelled by the burgeoning digital infrastructure, which includes cloud platforms and the increasing allure of hyperscale facilities.
Key drivers such as artificial intelligence, big data analytics, and dense computing needs have heightened the demand for effective heat management strategies in modern data centers. Consequently, there is a growing requirement for advanced refrigerants designed to ensure both energy efficiency and operational stability. This shift is notably affected by the sector's transition away from high-global-warming-potential refrigerants.
Global regulatory pressures stemming from climate agreements and evolving environmental policies are further accelerating this trend. Operators are diligently working to adapt by improving emission cuts, leakage controls, and lifecycle management, aligning with the industry's enhanced focus on sustainability and cost-efficiency.
The rise of hydrofluoroolefins (HFOs) is prominent, capturing a 67.7% market share in 2025. HFOs are increasingly preferred due to their lower global warming potential and substantial cooling efficiency. Anticipations are set for the market to experience a 10.2% CAGR through 2035, supported by the phase-out of conventional high-GWP refrigerants.
In terms of regional performance, the hyperscale segment stands out with a forecasted growth rate of 10.4% between 2026 and 2035. The U.S. continues its command over the domain with a 79% market hold, largely owed to rapid hyperscale centre expansions. Investments from leading tech giants aiming to upscale operational efficiency fuel the demand for cooling systems and high-performance refrigerants.
The future dictates a need for expanded production capabilities and robust supply chains within high-demand regions. Moreover, innovations focused on compliance, leakage detection improvements, and advanced lifecycle management highlight the industry's commitment to sustainable development.
