China says 'world's first' offshore wind-powered underwater data center has entered full operation, houses 2,000 servers — 24 megawatt subsea AI facility uses ocean water for passive cooling and offshore wind for power

China’s offshore wind‑powered underwater data center in Shanghai has begun full commercial operation.
The 24 MW facility near Shanghai houses nearly 2,000 servers and uses seawater for passive cooling.
The project is a public‑private partnership involving the Chinese government, HiCloud Technology, and state telecoms.
Officials say the design lowers cooling energy needs, improving efficiency with a PUE reportedly below 1.15.
The underwater setup connects to offshore wind farms for renewable energy supply.
Experts caution about saltwater corrosion and maintenance challenges for subsea racks.
The Shanghai project follows earlier submerged data center tests, such as Microsoft Natick.
The project aligns with a broader push to embed renewables in digital infrastructure.
Engineers must manage seawater environmental risks and subsea maintenance for long‑term operation.
