China has launched its first underwater data center in the Lin-gang Special Area of Shanghai, surpassing Microsoft in digital infrastructure innovation. Developed by Shanghai Hicloud with partners like China Telecom and Shenergy, the project cost approximately $226 million.

The data center operates at a depth of 35 meters, utilizing natural sea cooling and offshore wind energy, achieving a Power Usage Effectiveness (PUE) below 1.15. Initially generating 2.3 megawatts, it is planned to expand to 24 megawatts, with 95% of electricity supplied by offshore wind. The project highlights a shift towards underwater infrastructure for efficiency and sustainability, although maintenance may prove more complex than onshore installations.
