The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .
Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
Compressed air energy storage is a large-scale energy storage technology that will assist in the implementation of renewable energy in future electrical networks, with excellent storage duration, capacity and power. The reliance of CAES on underground formations for storage is a major limitation to the rate of adoption of the technology.
Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems . Compressed air energy storage systems are sub divided into three categories: diabatic CAES systems, adiabatic CAES systems and isothermal CAES systems.
Worldwide electricity storage operating capacity totals 159,000 MW, or about 6,400 MW if pumped hydro storage is excluded. The DOE data is current as of February 2020 (Sandia 2020). Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today.
Flywheels and Compressed Air Energy Storage also make up a large part of the market. The largest country share of capacity (excluding pumped hydro) is in the United States (33%), followed by Spain and Germany. The United Kingdom and South Africa round out the top five countries.
