""Underwater operations have inherent advantages," Highlander vice president Yang Ye told the South China Morning Post. This includes heat being dissipated by ocean currents, rather than the energy-intensive cooling systems used by datacenters operating on dry land. The method is understood to translate into a saving of approximately 90 percent on the energy consumption that would otherwise be required for cooling."
"Power for the littoral bit barn will be supplied largely from nearby offshore wind farms, with the expectation that about 95 percent of the energy used by the facility will come from renewable sources. Many Reg readers will recall that Microsoft famously experimented with underwater datacenters between 2015 and 2020 in trials designated Project Natick. These saw a small prototype facility deployed first in California to prove the concept, then a larger version lowered to the sea floor off Scotland's Orkney Islands."
China is advancing underwater datacenter deployments, with Highlander Digital Technology planning a seabed installation off Shanghai following a Hainan trial. The facility will serve customers including China Telecom and a state-owned AI computing company. Ocean currents will dissipate heat, reducing the need for energy-intensive cooling systems and cutting cooling energy consumption by roughly 90 percent. Power will be supplied largely from nearby offshore wind farms, with an expectation that about 95 percent of the facility's energy will come from renewable sources. Microsoft previously tested submerged datacenters in Project Natick between 2015 and 2020 but did not commercialize the technology.
