Executive Summary
China has brought a commercial underwater data center near Shanghai into full operation, pairing subsea server modules with offshore wind power and seawater cooling. The project is being framed as a test case for reducing land use, cooling demand, and electricity intensity as AI-driven compute loads grow. It also raises unresolved questions about durability, maintenance, and marine environmental impact at commercial scale.

Key Points
- The facility near Shanghai is now operating commercially as an underwater data center powered largely by offshore wind.
- Seawater is used as a passive heat sink, reducing cooling needs compared with conventional land-based centers.
- The project is designed around about 24 MW of capacity, with current operations reported around 2.3 MW in pilot or initial use.
- The site reportedly contains roughly 192 server racks, including GPU-oriented workloads tied to AI and data processing.
- Officials and company reporting emphasize lower land use, reduced electricity consumption, and high renewable energy share.
- Engineering risks remain significant, especially corrosion, pressure sealing, subsea cable reliability, and maintenance access.
- The deployment is being treated as a practical test of whether underwater computing can scale beyond experimentation.
