China debuts underwater AI data center

June 11, 2026

China has officially activated the world’s first offshore wind-powered underwater data center, marking a major breakthrough in sustainable digital infrastructure and energy-efficient computing.

Located approximately 10 kilometers off the coast of Shanghai, the Shanghai Lingang Undersea Data Center is positioned around 10 meters beneath the ocean surface and operates using electricity generated by a nearby offshore wind farm. The innovative facility is designed to support the rapidly growing demand for artificial intelligence (AI), cloud computing, and data processing while significantly reducing environmental impacts.

A new approach to data center sustainability

Data centers are becoming increasingly essential for powering AI applications, but they also consume enormous amounts of electricity and water. Traditional facilities often require extensive cooling systems that account for a substantial share of their energy consumption.

By placing servers underwater, engineers can take advantage of the ocean’s naturally stable temperatures. Seawater acts as a passive cooling resource, dramatically lowering the need for energy-intensive cooling equipment. According to project developers, the facility uses more than 20% less electricity than comparable land-based data centers.

The project has an initial capacity of 24 megawatts and is expected to provide a model for future low-carbon computing infrastructure. The center is powered primarily by renewable energy generated from offshore wind turbines, helping reduce dependence on fossil fuels while supporting China’s clean-energy goals.

Reducing water consumption

Beyond energy savings, underwater data centers may help address one of the technology sector’s growing challenges: water use. Conventional data centers require large volumes of freshwater for cooling, creating additional pressure on water resources.

The submerged design eliminates most freshwater cooling requirements by transferring heat directly through sealed systems that utilize surrounding seawater. This makes the facility particularly attractive as global demand for AI infrastructure continues to expand.

From concept to commercial deployment

While underwater data centers have been tested before, most notably through experimental projects in Europe, China has become the first country to deploy a commercial-scale facility that combines underwater computing with offshore wind power generation. Experts view the project as an important step toward integrating renewable energy and digital infrastructure.

The Shanghai installation follows an earlier underwater data center launched in southern China and demonstrates how marine engineering, renewable energy, and advanced computing can work together to create more sustainable technology solutions.

Challenges and future potential

Despite its advantages, underwater computing presents technical challenges, including long-term equipment maintenance, corrosion protection, and monitoring potential impacts on marine ecosystems. Researchers say ongoing environmental assessments will be essential to ensure the technology remains sustainable over time.

As AI-driven computing demand continues to rise worldwide, projects like the Shanghai Lingang Undersea Data Center could help shape the next generation of energy-efficient digital infrastructure, offering a cleaner and more resource-efficient alternative to traditional data centers.
