Economic Analysis and Outlook of Compressed Air Energy Storage Technology in China
With the increasingly prominent'double high'characteristics of the new power system,the demand for new energy storage with long cycle,high security and physical rotational inertia is becoming more and more urgent.Compressed air energy storage has advantages such as large scale,high reliability,long lifespan,and low cost.The single-unit scale of compressed air energy storage in China has reached 300MW,which is a useful supplement to pumped hydro long-term energy storage.This paper focuses on analyzing the technical principles and characteristics of compressed air energy storage,calculates the levelized cost of energy storage,and estimates the cost reduction space in the future based on the two-factor learning curve model.It is expected that by 2030,the electricity cost per kilowatt-hour of hundreds of megawatts level compressed air energy storage can be reduced to 0.35 to 0.4 Yuan/kWh,and there is a cost reduction space in all links.The compressed air energy storage technology in China needs to explore in aspects such as top-level design,technology research and development,and business model in order to achieve considerable development.
