We look at Planet First Partners as they back cooling tank technology that cuts down data center climate impact and how this investment in Submer’s energy and water saving technology will accelerate expansion.

Sustainable investor Planet First Partners (“Planet First”) has become a significant investor in Submer, a pioneering growth stage company solving an emerging environmental threat – high energy consuming data centers. 

Founded in Barcelona in 2015, Submer has developed a patented immersion cooling technology as an alternative to the air-based cooling systems, which are currently the dominant solution for data centers around the world. The company’s technology is already used by major information technology companies like Telefónica and is endorsed by Intel. 

Energy consumption by data centers has become an urgent issue. Globally, data centers are projected to consume 10% of electricity and be responsible for 2.75% of greenhouse emissions by 2025, placing them above the airline industry in terms of their carbon footprint. In Ireland, they are expected to use almost 30% of their electricity by 2028. In order to reduce the electricity bill, air-based systems rely on evaporative cooling technologies that can also consume enormous quantities of water, with larger facilities getting through the volume of an Olympic pool every 48 hours. With data centers growing at projected annual rates of 2-6% and energy efficiency gains plateauing since 2018, urgent solutions are needed to mitigate this growing energy footprint. 

Submer’s technology offers a new and unique way to meet these challenges. It works by cooling data center server units in modular tanks filled with a biodegradable electrically non-conductive liquid which absorbs the heat and dissipates it through heat exchangers for efficient reuse in commercial and industrial settings. The technology eliminates the use of refrigerant gas and uses 50% less energy, 99% less water and 85% less real estate than traditional cooling methods. As well as being better for the planet, Submer’s cooling system also delivers significant cost savings for data center owners and future proofs them against evolving regulation on emissions and growing processing power, and hardware density requirements.    

Planet First is the lead investor in the latest (third) USD34m funding round announced today and will be joining Submer’s existing shareholders including Norrsken VC, Alma Mundi Ventures and Tim Reynolds. The funding will accelerate Submer’s international expansion into the North America and APAC regions and fund R&D initiatives around next generation liquid coolants and data center automation.  

“Our mission at Submer has always been to offer best-in-class solutions to the data center industry to help turn their impact on the environment into a positive,” commented Daniel Pope, CEO and Co-founder of Submer and Pol Valls, COO and Co-founder at Submer. Pope added, “the

time is now for the industry to make the necessary steps to reduce its environmental impact and ensure it can compete in a market where society and customers expect net zero or even net-positive services. Thanks to this new investment, Submer is in a great position to grow the business and continue to invest in developing new technologies that truly change the industry.”  

Frédéric de Mévius, Co-Founder and Managing Partner at Planet First Partners, said, “The partnership with Submer lies in the sweet spot of our investment mandate: the intersection of strong sustainability credentials with innovative technology and consumer preferences.” de Mévius added, “we believe that Submer’s immersion cooling pods will play a key role in making data centers sustainable, assuring the future growth of the data-enabled economy. Moreover, our partnership with Submer is in full alignment with the EU’s criteria for investment in economic activities substantially contributing to the environmental objective of Climate Change Mitigation.” 

Andreea Constantinescu, Partner at Planet First Partners, added: “We are incredibly excited about joining Daniel, Pol and the Submer team on their journey to make data centers and computing environmentally sustainable.” Constantinescu said, “we believe that Submer’s core ext generation cooling technology, the entrepreneurial drive and long-term vision for “data centers that make sense” and the strong ecosystem partnerships developed to date will catalyze mainstream adoption for immersion cooling.”
