Abstract: In order to explore the environmental benefits of energy storage and promote large-scale development of energy storage, by incorporating energy storage into the green certificate market and carbon market, a measurement method of energy storage participation in the green certificate and carbon market is proposed. Further an economic benefit model of energy storage based on the perspective of environmental effects is established. Combined with the emission factors of various regional power grids in China, the economy of energy storage is deeply studied. The results show that the economy of energy storage can be improved after the inclusion of green certificate and carbon market, but the overall effect is limited, and compared with electrochemical energy storage, pumped storage currently has better economic efficiency. From the perspective of energy storage type, pumped storage can get better benefits to participate in the green certificate market, and electrochemical energy storage is recommended to participate in the carbon market. From the perspective of regional power grids, the participation of energy storages in North China, Northeast China and Northwest China power grids have a good economy to join the carbon market.
