News: Will Computers of the Future Be Submerged in Liquid?

Cooling computers is becoming one of the biggest energy challenges of the digital age. Today, data centres spend up to 50% of their total electricity just on cooling servers. With the rapid growth of artificial intelligence, this demand is expected to more than double by 2030.

A recent article on Gemini.no highlights how liquid cooling could provide an energy-efficient alternative to traditional air cooling—while also enabling heat recovery for reuse in district heating and industry.

Researchers from SINTEF and Synapsecom, working within the EU-funded MODERATOR project, are exploring immersion cooling, where entire servers are submerged in a dielectric liquid. This method not only cools components efficiently but also makes it possible to capture heat at useful temperatures (50–70°C) for reuse in heating buildings or industrial processes.

The article discusses two main approaches—direct liquid cooling of specific parts and immersion cooling of entire systems—and notes that the most effective solutions may combine both. With careful material selection and advanced modelling, MODERATOR is helping pave the way toward greener, more sustainable data centres.
