The operational principles of thermal energy storage systems are identical as other forms of energy storage methods, as mentioned earlier. A typical thermal energy storage system consists of three sequential processes: charging, storing, and discharging periods.

How does a thermal energy storage system work?

There is cooling of the air as it flows via the thermal energy storage device, followed by an after-cooler. From this stage, there is compression of the air until required pressure is achieved. This means that the temperature of the air is again raised to 380 °C. There is an exchange of heat in the second thermal energy storage system.
