An overview of thermal energy storage systems
Thermal energy storage at temperatures in the range of 100 °C-250 °C is considered as medium temperature heat storage. At these temperatures, water exists as steam in atmospheric pressure and has vapor pressure. Typical applications in this temperature range are drying, steaming, boiling, sterilizing, cooking etc.
