Energy storage systems

Each energy input or output causes an increase or decrease of the temperature. Latent heat storage systems additionally use the phase transition of the storage material from solid to liquid and the other way round. During the phase transition, the storage material can absorb or release large amounts of energy at almost constant temperature.
