Abstract: Adiabatic Compressed Air Energy Storage (ACAES) is regarded as a promising, grid scale, medium-to-long duration energy storage technology. In ACAES, the air storage may be isochoric (constant volume) or isobaric (constant pressure).

To enhance the efficiency and reduce the fossil fuels, researchers have proposed various CAES systems,such as the adiabatic compressed air energy storage (A-CAES) , isothermal compressed air energy storage (I-CAES) , and supercritical compressed air energy storage (SC-CAES) .
The modeled compressed air storage systems use both electrical energy (to compress air and possibly to generate hydrogen) and heating energy provided by natural gas (only conventional CAES). We use three metrics to compare their energy use: heat rate, work ratio, and roundtrip exergy efficiency (storage efficiency).
Compared to compressed air energy storage system, compressed carbon dioxide energy storage system has 9.55 % higher round-trip efficiency, 16.55 % higher cost, and 6 % longer payback period. At other thermal storage temperatures, similar phenomenons can be observed for these two systems.
Compressed air energy storage (CAES) is a relatively mature technology with currently more attractive economics compared to other bulk energy storage systems capable of delivering tens of megawatts over several hours, such as pumped hydroelectric [1–3]. CAES stores electrical energy as the exergy of compressed air.
Thermodynamic-economic performances of different systems are compared. Air is overall superior to carbon dioxide in compressed energy storage. Currently, working fluids for adiabatic compressed energy storage primarily rely on carbon dioxide and air. However, it remains an unresolved issue to which of these two systems performs better.
System structures are developed at different fluids and thermal storage temperatures. Quasi-dynamic models are developed for compressed energy storage systems. Variations of different system parameters over time are compared and analyzed. Thermodynamic-economic performances of different systems are compared.
