Submer, a leader in cooling technology, has successfully secured $55.5 million in new funding to support its expansion efforts. With its headquarters in Barcelona and a manufacturing presence in Houston, Texas, the company is actively addressing sustainability in datacenters, a growing concern as AI accelerates demand.

The investment, led by M&G alongside existing backers Planet First Partners and Norrsken VC, aims to bolster the use of Submer’s immersion cooling technologies. As data centers increasingly face energy and water consumption challenges due to high-performance hardware driven by AI workloads, Submer advocates for liquid cooling as a necessary evolution.

Recent reports highlight the severe environmental impact of data centers. A study indicates that without intervention, these facilities could emit 2.5 billion tonnes of greenhouse gases globally by the decade’s end.

In the UK, new data center projects face fewer planning hurdles as they gain recognition as essential infrastructure. Significant projects include Atlantic Hub’s development in Northern Ireland and Kao Data’s £350 million facility in Greater Manchester, poised to power AI workloads by 2026.

Driven by a report indicating that over a third of enterprises plan to implement liquid cooling by 2026, Submer emphasizes its efficiency in reducing the energy devoted to traditional air conditioning systems by up to 20 percent, using non-conducting fluids instead of water.

Submer’s solutions arrive at a crucial moment, with companies like Supermicro predicting liquid cooling installations in significant portions of their shipped racks next year, and Equinix expanding its support for liquid cooling technologies globally.

Exploring innovative cooling solutions, Japan uses snow to cool infrastructure, subsequently utilizing meltwater for agriculture. Meanwhile, Tomorrow Water in Korea plans to integrate datacenters with sewage facilities, merging waste treatment and cooling operations.
