Recently, the liquid air energy storage demonstration project, designed and manufactured by Lanzhou LS Heavy Equipment Co., has been completed and delivered in stages. The project uses a new generation of compressed air energy storage technology to store electric energy in the form of liquid air at atmospheric pressure, low temperature, and high density, solving the problems of air storage and constant pressure release. After the project is put into operation, it will become the world's largest demonstration project in terms of power generation and energy storage capacity in the field of liquid air energy storage.
