China Launches World's First Wind-Powered Underwater Datacenter

WireByte Staff · June 9, 2026

China has launched the world's first wind-powered underwater datacenter near Shanghai. The facility utilizes natural seawater cooling, significantly reducing energy and water consumption compared to land-based operations. This initiative addresses the growing energy demands of AI development, offering a potentially more sustainable solution for the booming sector.

Key points

  • HiCloud Technology and China Communications Construction launched the world's first wind-powered underwater datacenter near Shanghai.
  • The Shanghai Lingang undersea datacenter demonstration project is situated 10 kilometers offshore and 10 meters beneath the water's surface, drawing power from a nearby offshore wind farm.
  • The underwater datacenter reportedly reduces power consumption by over one-fifth compared to traditional land-based datacenters, thanks to natural seawater cooling.
  • The project aims to address the growing energy demands of China's artificial intelligence industry, which has been criticized for its significant environmental footprint.
  • The United Nations University Institute for Water, Environment and Health has previously warned about the immense water footprint of traditional datacenters.

A groundbreaking facility, billed as the world's first wind-powered underwater datacenter, has begun operations off the coast of Shanghai. This pioneering project, a collaboration between HiCloud Technology and China Communications Construction, aims to tackle the substantial energy needs of China's burgeoning artificial intelligence industry.

The Shanghai Lingang undersea datacenter demonstration project, launched in May, is situated more than 10 kilometers offshore and submerged 10 meters beneath the water's surface. It draws its power from a nearby offshore wind farm. A key advantage highlighted is its energy efficiency; the submerged location leverages the natural cooling effect of seawater, reportedly reducing power consumption by over one-fifth when compared to conventional land-based datacenters. This also alleviates concerns about the significant water usage typical of traditional facilities, which often require extensive cooling systems using freshwater.

The development comes amid growing global scrutiny of the environmental footprint of datacenters, which are crucial infrastructure for AI. The United Nations University Institute for Water, Environment and Health has previously warned about the immense water footprint of such facilities.
