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

Sensible Heat Storage

Sensible heat storage means shifting the temperature of a storage medium without phase change. It is the most common simple, low-cost, and longstanding method. This storage system exchanges the solar energy into sensible heat in a storage medium (usually solid or liquid) and releases it when necessary.
