Introduction to thermal energy storage (TES) systems

Thermal energy storage (TES) systems can store heat or cold to be used later under varying conditions such as temperature, place or power. The main use of TES is to overcome the mismatch between energy generation and energy use [1., 2., 3 TES systems energy is supplied to a storage system to be used at a later time, involving three steps:

Condensing Gas Tank Water Heaters. Both tanked and tankless gas heaters send hot exhaust gases out of the flue, which wastes energy. A high-efficiency condensing gas water heater redirects the exhaust heat to the water. Condensing gas water heaters are extremely efficient, though the initial purchase price is higher than a standard efficiency

Liquid Air Energy Storage System

During the discharge cycle, the pump consumes 7.5 kg/s of liquid air from the tank to run the turbines. The bottom subplot shows the mass of liquid air in the tank. Starting from the second charge cycle, about 150 metric ton of liquid air is produced and stored in the tank. As seen in the scope, this corresponds to about 15 MWh of energy storage.
