Shanghai has completed the first phase of the world’s first wind-powered undersea data centre. Located in the Lin-gang Special Area, the facility is almost entirely powered by offshore wind energy. Its innovative design uses seawater cooling, reducing energy demand for cooling to less than 10%.
This project represents a major step in China’s push for greener infrastructure. By situating the data centre underwater, land use is cut by over 90%, while overall energy consumption decreases by roughly 22.8%. Experts say this approach could redefine data centre design and environmental sustainability.
The facility’s technology combines wind energy generation and advanced seawater cooling. Offshore turbines supply clean power, while seawater cooling lowers energy needs for temperature control, a major contributor to data centre energy use. Engineers say this combination could serve as a model for future energy-efficient data infrastructure.
Located in the Lin-gang Special Area, Shanghai’s undersea data centre is positioned strategically near ports and renewable energy sources. The project supports China’s national goals to reduce carbon emissions and shift to cleaner energy sources. Officials say this is part of a broader plan to integrate sustainable technology into urban infrastructure.
The data centre will also play a role in digital innovation. With its reduced environmental footprint, it can host cloud computing, AI processing, and large-scale data storage while maintaining energy efficiency. Analysts suggest this model could inspire other coastal cities to explore underwater, wind-powered data facilities.
China’s green transition is gaining momentum, and projects like this highlight the country’s commitment to sustainability. By combining renewable energy, underwater construction, and efficient cooling systems, the Shanghai facility demonstrates how technological innovation can support both economic and environmental goals.
The project also aligns with global trends in sustainable technology. Data centres worldwide consume massive amounts of energy, and innovations like wind-powered underwater facilities could help curb the environmental impact of the digital economy.
Future phases of the Shanghai project are expected to expand capacity and integrate additional renewable energy sources. Engineers aim to further reduce energy consumption and enhance operational efficiency, making the facility a benchmark for environmentally friendly data infrastructure.
This undersea data centre also offers lessons for urban planning. By moving high-energy facilities offshore, cities can save land and reduce heat generation in dense urban areas. Combined with renewable energy, this approach could become a key strategy in climate-conscious urban development.
Experts say the successful implementation of this wind-powered undersea data centre reflects China’s growing expertise in combining engineering innovation with green policies. It positions Shanghai as a leader in sustainable technology and sets a new standard for how cities manage digital infrastructure responsibly.
