Abstract: Renewable energy application is an inevitable trend of world development. Renewable energy can be stored by liquefied air energy storage technology. Liquefied air energy storage technology can be applied not only to store renewable energy but also to solve the problem of peak-valley difference in grid. In this paper,the development status of liquid air energy storage technology is introduced in detail. The various parameters of liquefied air energy storage technology are analyzed and compared with other energy storage technologies. It is convenient for Engineering and technical personnel to understand liquid air energy storage technology intuitively.
