Abstract:

Energy storage is the key technology to achieve the initiative of "reaching carbon peak in 2030 and carbon neutrality in 2060".Since compressed air energy storage has the advantages of large energy storage capacity, high system efficiency, and long operating life,it is a technology suitable for promotion in large-scale electric energy storage projects, and also an important means of large-scale renewable energy consumption on grid side. The development process, working principles, research statuses and challenges of compressed air energy storage systems in different forms are comprehensively expounded, and the development trend of compressed air energy storage technology is analysed from the perspective of compressed heat storage, providing references for the design for the future systems. The research results show that with the development of high-temperature heat storage technologies, high temperature adiabatic compressed air energy storage technology has become a research hotspot in this field because of its extraordinary working efficiency. Taking the molten salt with low melting point as the heat storage medium of a compressed air energy storage system to store the heat from the high-temperature compressor, can reduce the storage temperature of compressed water and the initial investment cost of the compressed air energy storage system significantly.

Key words: carbon neutrality, compressed air energy storage, renewable energy, electrical power system, thermal storage technology
