First offshore wind-powered undersea data centre in China
25/6/2025
News
China’s first offshore wind power-integrated undersea data centre has been launched, marking a step forward for China’s green digital economy.
The project, led by Shanghai HiCloud Technology Company, is backed by a ¥1.6bn ($220mn) investment and brings together the public and private sector in a new model of low-carbon, ocean-based data services.
Unveiled at a signing ceremony attended by Shanghai officials and leading industry partners, the Lingang Undersea Data Centre initiative combines undersea infrastructure with direct access to offshore wind power.
The project will be developed in two phases, with a total capacity of 24 MW and a pilot phase of 2.3 MW. The project boasts a power usage effectiveness (how much energy is used by the computing equipment compared to cooling demand) of no more than 1.15. It is also said to have a green energy usage rate of over 97%.
The facility will be the first in the country to combine ocean cooling with direct offshore wind energy supply. It is hoped the new ‘land-based data, sea-based computing’ model will meet the growing demand for AI, 5G and high-performance computing.
