The thermodynamic performance of some representative CAES (Compressed Air Energy Storage) plant configurations is computed both at steady-state nominal point and during time-variable conditions, by making use of a simulation technique capable of accounting for thermal inertia of recuperators and TES (Thermal Energy Storage), for part-load characteristics of turbomachinery and for power regulation modes. The results of the analysis are presented in terms of the energy losses caused by the irreversibilities occurring in the various plant components, with reference to the second law of thermodynamics.
