1 Basic thermodynamics of thermal energy storage

energy storage. 1.1.1 Sensible heat By far the most common way of thermal energy storage is as sensible heat. As fig.1.2 shows, heat transferred to the storage medium leads to a temperature in-crease of the storage medium. A sensor can detect this temperature increase and the heat stored is thus called sensible heat. Methods for thermal energy
