Liquid cooling and heat recovery redefine efficiency Cooling remains one of the most energy-intensive aspects of data centre operations, making it a focal point for optimisation efforts. As traditional air-based systems reach their limits, liquid cooling technologies are emerging as a viable alternative for high-density environments.
Research into warm-water liquid cooling, immersion systems and two-phase cooling is enabling more efficient heat transfer while reducing overall energy consumption. These approaches are particularly suited to AI workloads, where concentrated heat generation requires more direct and effective cooling methods.
At the same time, waste heat recovery is gaining traction as a way to extend energy optimisation beyond the data centre itself. By capturing and repurposing excess thermal energy, operators can reduce overall energy loads and contribute to local energy systems.
