Shanghai has completed the first phase of the world’s first wind-powered undersea data centre. Situated in the Lin-gang Special Area, the facility runs almost entirely on offshore wind energy. It uses seawater cooling, lowering energy demand for cooling to less than 10%.
The project marks a significant step in China’s green infrastructure drive. Placing the data centre underwater reduces land use by over 90% and cuts total energy consumption by nearly 23%. Experts say it could reshape how cities design and power data centres sustainably.
The facility combines renewable energy with advanced seawater cooling. Offshore wind turbines provide clean power, while seawater keeps the servers cool efficiently. This approach dramatically reduces electricity needed for temperature control, a major energy cost for traditional data centres.
Located near ports and wind resources, the Lin-gang Special Area is ideal for this innovation. Officials say the project supports China’s environmental goals and contributes to the country’s shift toward cleaner energy and low-carbon urban planning.
The undersea data centre also advances digital infrastructure. It can support cloud computing, AI processing, and large-scale data storage while maintaining a minimal environmental footprint. Analysts suggest this could inspire other coastal cities to adopt similar offshore, wind-powered data solutions.
China’s commitment to sustainability is reflected in projects like this. Combining renewable energy, submerged construction, and efficient cooling demonstrates how technology can reduce environmental impact while supporting economic growth.
Global data centres consume massive amounts of electricity, and innovations like Shanghai’s facility could set a new standard. Wind-powered underwater systems may become key to lowering emissions in the digital economy.
Future phases of the project plan to expand capacity and integrate more renewable energy sources. Engineers aim to further improve efficiency, making the facility a benchmark for environmentally responsible data infrastructure.
By moving high-energy operations offshore, cities can save land and reduce urban heat. This strategy, combined with renewable energy, shows how sustainable urban planning and technological innovation can work together.
Experts say Shanghai’s wind-powered undersea data centre highlights China’s growing expertise in green technology. The project positions the city as a leader in eco-friendly digital infrastructure and offers a model for other nations seeking sustainable solutions.
