Datacenter sustainability group The Green Grid is devoting some of its resources to investigating the potential of direct liquid cooling (DLC) to improve datacenter efficiency.  DLC is a method of heat dissipation where the processors (or other components) are in close proximity to – or fully immersed in – a liquid. Green Grid is planning to establish a liquid cooling initiative within its technical committee that will address aspects of the data center that are impacted by DLC, including facility physical planning, water quality best practices, as well as management interface between data centers and DLC technologies. The organisation is expected to help with the process of establishing standards for DLC. The RenewIT project is also investigating the potential of DLC to improve datacenter efficiency including heat-reuse and will look to participate in The Green Grid efforts.
