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.
Thermal Energy Storage Overview
Technology Description. TES technologies are often grouped into three categories: 1) sensible heat (e.g., chilled water/fluid or hot water storage), 2) latent heat (e.g., ice storage), and 3) thermo-chemical energy. 5. For CHP, the most common types of TES are sensible heat and latent heat.
