China has launched the first underwater commercial data center of its kind in Hainan Province, according to state-owned news outlet CGTN. The data center consists of a shore station that emits signals to facilitate vessel navigation, an underwater relay station, submarine cables, and an underwater data terminal. The placement of data servers on the seabed allows the seawater to act as a natural coolant, which should save 30% on energy costs, according to the news outlet. It will also save land resources and enhance security.

The data center has a life expectancy of 25 years, and the ability to provide oxygen at a depth of over 30 meters. The construction of the data center was put forward as a way to develop China’s infrastructure through the country’s 14th five-year plan for marine economic development of Hainan Province, where a total of 100 underwater data cabins will be set up.
