Since its creation in 2015, Overwhelm set itself the mission of designing a sustainable digital infrastructure and future-proof. The American company, having recently completed a financing round of $55.5 millionpositions itself as a key player in the data center market thanks to its immersion cooling.

A growing market: Data centers and AI

Submer targets a high growth sector, that ofartificial intelligence. Businesses around the world urgently need suitable infrastructure to host their services. The growing volume of data and the associated energy consumption are becoming major challenges.

Indeed, a study indicates that “on average, a ChatGPT request requires nearly 10 times more electricity to be processed than a Google search. » This observation highlights the need to rethink our energy consumption, with data centers currently representing between 1 and 2% of global electricity consumption, a figure that could reach 3 to 4% by 2030.

An innovative solution to energy challenges

Aware of the limits of air cooling and of liquid coolingSubmer has developed modular immersion cooling technology. This system consists of immersing the servers in a heat transfer fluid, which makes it possible to:

• Avoid overheating of machines.
• Reduce electricity consumption by 50%.
• Optimize space with a reduction of 85% real estate needs.
• Be installed almost anywhere.

The heat produced by the servers is evacuated by a cooling tower, which is also capable of reusing this heat to power other systems. With offices in Houston And Taipeiand an R&D center in SausalitoSubmer works with prestigious clients, including some of the top five suppliers of cloud, Airbusand the European Commission.

Growing Adoption of Immersion Cooling Technology

The trend toward alternative cooling methods is not unique to Submer. In 2020, Microsoft carried out its project Natick by going up a data center from the seabed in Scotland. The results showed that the hardware had held up and operated efficiently using renewable energy, paving the way for similar applications for terrestrial data centers.

The future of data centers

As the demand for efficient cooling solutions increases, Overwhelm demonstrates that the sustainability and innovation can go hand in hand in the data center industry. As businesses seek to reduce their energy footprint, the immersion cooling could well become the norm.

With promising results and planned expansion, Submer’s solution could transform the way we design and manage data centers in the years to come.
