Thermal energy storage systems are secondary energy storage systems that store heat. They can be grouped by their technical use: • Sensible heat storage systems store energy with a medium change in temperature before and after charging, which can be "sensed." This is multiplied by the heat capacity and mass of the medium to determine the amount of energy stored.
