This type of solar plants uses direct energy storage, resulting that heat transport fluid and the heat transfer fluid (HTF) are the same molten salts. The liquid salt at 290 °C is pumped from a ''cold'' storage tank through the receiver which is heated until it reaches 565 °C, returning after to a ''hot'' tank for its storage [ 3 ].
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.
