China’s $226 Million Undersea Data Center Nears Full Operation, Cutting Land and Water Use for AI
China has brought a pioneering undersea data center near Shanghai into full operation, a project that industry experts say could reshape how the world powers the energy-intensive artificial intelligence boom. The facility, located ten meters below the surface off the Lingang Special Area, is designed to tackle one of AI’s fastest-growing challenges: building massive computing capacity without straining energy, water, and land resources.
The undersea data center houses 192 server racks across four levels and has drawn approximately $226 million in investment. While its total planned power capacity is 24MW, only 2.3MW is currently in use. Developers report that as much as 95% of the facility’s electricity comes from green sources, primarily offshore wind power, with the surrounding ocean providing natural cooling.
The environmental gains are significant. According to developers, the facility uses no water for cooling and reduces land use by 90% compared to traditional onshore data centers. It is also expected to save 61 million kilowatt-hours of electricity each year. “For a sector under pressure to reduce its environmental footprint, the design is significant,” the project team stated, noting that the model directly addresses the resource constraints that have become a mounting ESG concern for governments and technology companies.
The project arrives as AI workloads demand ever-larger volumes of computing power, requiring more GPUs, more server racks, and more electricity. Traditional data centers often consume vast amounts of power and water, especially in regions with high cooling demand, turning digital infrastructure into a growing ESG issue. Companies need capacity for AI growth, but regulators, investors, and communities are increasingly asking how that capacity will be built.
China’s undersea model offers a potential solution by combining ocean cooling with offshore wind power, reducing reliance on conventional water-based systems and fossil-fuel electricity. The Lingang Special Area, a hub for advanced technology and strategic industries, provides the policy backdrop for the project, which supports China’s broader push to scale AI infrastructure while managing resource constraints.
For investors and executives, the implications are clear. “Future data center assets may be assessed not only on computing capacity, but also on power sourcing, water intensity, and land efficiency,” the project developers noted. Those metrics are already moving higher on the ESG agenda, and data centers that can demonstrate lower operating emissions and reduced resource demand may gain a competitive advantage as reporting rules tighten and buyers seek cleaner cloud and AI services.
China is not the first to test underwater data centers. Microsoft explored the concept through Project Natick, which placed a data center on the ocean floor and reported strong results, though it did not push the model into broad commercial rollout. China’s latest project suggests the concept may now be moving closer to real-world infrastructure planning, with developers indicating plans to expand deployments in future.
The race to build AI capacity is accelerating, with some firms even exploring data centers in space—a far more expensive and experimental route. Undersea data centers offer a more immediate comparison, using existing marine conditions, connecting to offshore wind resources, and reducing pressure on urban energy and water systems. “If the model proves scalable, it could influence how coastal economies plan the next wave of digital infrastructure,” the project team said. The wider question is whether global AI growth can align with climate and resource goals before power demand becomes a larger constraint.
