The steam supplied to the thermal storage condenses in a volume of colder water, while the temperature and pressure in the tank increase. The water in the storage is overheated in its entire volume (({t}_{Water}>100^circ mathrm{C})) due to the state of saturation, after a sudden drop in pressure (opening of the valve), an abrupt …
The high-pressure air passes through two heat exchangers to obtain the energy level at low temperature from intermediate fluids, which are methanol and propane from the cold energy storage. Then the air enters a cryoturbine to expand to ambient pressure, which results in a gas and liquid mixture that is sent to a separator.
However, in some cases, the continued decline of wind and solar costs could negatively impact storage value, which could create pressure to reduce storage costs in order to remain cost-effective. "It is a common perception that battery storage and wind and solar power are complementary," says Sepulveda.

CAES with heat storage, PTES and LAES are expected to reach efficiencies of 60-70%, 50-75% and 45-70% respectively. While batteries can achieve higher efficiencies (60-90%), TMES technologies benefit strongly from economies of scales, so often have lower projected costs – often below $100/kWh – for large plants.
