In advanced adiabatic CAES (AA-CAES), the thermal energy generated by the compression of the air is not rejected, but captured in a thermal-energy storage (TES) before entering a reservoir. (We use “reservoir” as a generic term for both underground storage volumes such as caverns as well as for above-ground storage volumes such as tanks.)
New models developed for adiabatic reservoirs and turbomachinery, without throttling. Models give expressions for plant efficiency and storage capacity. Models can be used for initial plant design by estimating reservoir volumes. Reduced maximum process temperatures imply reduced plant efficiencies.
Thermodynamic Model In the thermodynamic model for the AA-CAES system, the assumptions are listed below: - The air circulates in the close loop cycle and is considered as an ideal gas. - Storage vessel is assumed to be well insulated and no heat loss across the vessel.
A novel water cycle compressed air energy storage system (WC-CAES) is proposed to improve the energy storage density (ESD) and round trip efficiency (RTE) of A-CAES. The new system decreases electricity consumption by recovering and reusing the hydraulic pressure of water.
