The Asian giant has once again made a bold statement regarding technological sovereignty and sustainability. With the launch in full Shanghai coastline of its first underwater data centerThe country is not only seeking to expand its computing power, but to do so in a way that doesn't further inflate its already substantial energy bill. This facility, a pioneer in combining an underwater location with direct power from an offshore wind farm, is presented as the logical answer to modern artificial intelligence's voracious appetite for electricity.
To carry out such a large engineering project in the Lingang Special Area, it has been necessary to disburse some 226 millionThis figure demonstrates the seriousness of the commitment. It's not just a laboratory experiment, but a complete commercial infrastructure involving everyone from local authorities to leading technology firms like HiCloud Technology. This deployment is especially relevant now that Europe and Spain are closely scrutinizing how to reduce the environmental impact of their own digital hubs, which continue to grow in regions like Madrid and Barcelona.
Underwater infrastructure in the Lingang Special Area
What is truly surprising about this project is its operational capacity, as it features watertight modules that house some 2.000 high-performance serversProtected by a structure weighing around 1.950 tons, these systems are submerged at a depth of about ten meters. This location, while seemingly straight out of a science fiction film, makes perfect sense if the goal is to leverage the natural conditions of the environment to improve the performance of the processing clusters.
The location is not accidental, since being within an offshore wind farm allows it to take advantage of the force of sea wind through technologies such as floating offshore wind power to power the servers directly. This eliminates much of the energy loss that occurs when transmitting power over long distances and ensures that advanced computing processes, essential for 5G networks and the training of large language models, are carried out with a much smaller carbon footprint than is typical in the heavy technology industry.
Sustainability and natural liquid cooling
The great secret of this facility lies in its heat exchange system. Surrounded by cold water, the data center uses a passive cooling circuit This virtually eliminates the need for industrial air conditioning or large fans, which are typically the biggest energy consumers in land-based facilities. Thanks to this ingenious design, electricity savings of 22,8% are achieved compared to traditional installations, providing significant relief to the overall electrical grid.
Besides the savings on the electricity bill, there is another key environmental factor: water. While terrestrial data centers They consume enormous quantities of fresh water for its cooling towers, this underwater model It completely dispenses with fresh waterThis is fantastic news for areas suffering from water stress. With a power efficiency rating (PUE) of nearly 1,15, the facility is well ahead of most of its global competitors in terms of resource optimization.
Technical challenges under the South China Sea
Clearly, putting cutting-edge technology underwater is no walk in the park. Engineers have had to contend with the corrosion caused by saltpeter and the enormous hydrostatic pressure, designing ultra-resistant modules that can withstand years without constant physical intervention. To solve this problem, the center has a system of constant remote monitoring and security protocols that ensure the data is safe, even if surface conditions become adverse.
This data center is perfectly suited to support the boom in systems like DeepSeek or QwenThese initiatives have positioned China at the forefront of open-source AI. By providing infrastructure that costs less and performs better, the country ensures its race to lead the technology sector is not hampered by the energy constraints other global powers are already beginning to experience. Ultimately, it is a strategic move that combines naval engineering, clean energy, and cutting-edge computing.
The commissioning of this underwater infrastructure in Shanghai marks a milestone in the search for sustainable solutions for the digital sector, demonstrating that it is possible. combine energy efficiency and computing power by harnessing ocean resources. With a drastic reduction in electricity and freshwater consumption, this model not only addresses the immediate needs of artificial intelligence, but also offers a path forward for future technological deployments that aim to be environmentally friendly in any corner of the planet.
