China began commercial operations at the Lingang Underwater AI Data Centre, a subsea computing facility developed by HiCloud Technology and regional partners, featuring nearly 2,000 servers housed in pressure-resistant modules powered by adjacent offshore wind infrastructure. Located about 35 metres below the ocean surface, the project entered full operation in May 2026 following construction completion in late 2025 and trial deployments earlier this year.
The facility expanded from an initial 2.3MW demonstration project into a 24MW commercial operation supporting AI computing, cloud services, large language model development and data-processing workloads. The design uses sealed underwater modules connected through subsea power and fibre-optic networks, while a seawater-assisted cooling system helps dissipate heat and reduce reliance on conventional cooling equipment.
For enterprises and AI developers, the Lingang facility demonstrates a renewable-powered approach to scaling compute capacity while lowering land requirements and cooling energy consumption. The project reflects growing interest in pairing clean-energy infrastructure with high-density AI workloads as demand for computing resources continues to accelerate.

What Makes This Trend Stand Out
- Subsea Compute Infrastructure
- Submerged server modules introduce new real estate models for high-density computing by shifting capacity from constrained urban land to controlled offshore environments.
- Wind-powered AI Clouds
- Renewable-linked compute platforms are redefining AI infrastructure economics as colocated offshore wind generation supports lower-carbon model training and cloud workloads.
- Seawater Cooling Systems
- Ocean-assisted thermal management enables data centres to reduce mechanical cooling dependence while supporting denser server deployments for energy-intensive applications.
Sectors Adopting This
- Data Centers
- The sector is expanding beyond land-based campuses as underwater facilities offer alternative capacity pathways with reduced cooling loads and land-use pressures.
- Renewable Energy
- Offshore wind operators gain adjacent demand opportunities through direct integration with compute infrastructure that absorbs clean power for AI and cloud processing.
- Cloud Computing
- Cloud service providers face emerging infrastructure formats where subsea, renewable-powered facilities support scalable processing for enterprise workloads and large language models.
