The world's largest liquid air energy storage project is connected to the grid in Golmud, Qinghai to generate electricity

China News Service, Xining, October 30 (Sun Rui, Li Shasha) The world's largest 60-megawatt liquid air energy storage national demonstration project invested and constructed by China Green Development Investment Group Co., Ltd. ("China Green Development") was successfully connected to the grid for power generation on October 30, marking China's comprehensive mastery of liquid air energy storage technology. The localization rate of equipment has reached 100%, and energy storage power and capacity rank first in the world.

Air energy storage is to cool the air to minus 194 degrees Celsius and turn it into a liquid state, store it, and then release it to generate electricity when electricity is needed. It does not care about geological conditions, is safe and environmentally friendly, and can store electricity on a large scale and for a long time.

Although wind power and photovoltaic power are developing rapidly, they are dependent on the weather and fluctuate greatly. They cannot be saved or given away. This project realizes the "low valley storage and peak use" of new energy power, effectively solving the problem of wind and solar consumption. The project also cooperated with upstream and downstream units to develop a batch of the industry's first major equipment (sets), and all core equipment achieved breakthroughs in localization.

Ji Wei, chief engineer and chief expert of China Green Energy Storage Company, said that the project was successfully connected to the grid and achieved a large-scale leap from hundreds of kilowatts to tens of thousands of kilowatts, providing a new solution for solving the problem of wind and solar consumption and completing a key link in large-scale long-term energy storage.
