How it Works. A Concentrated Solar Thermal Power Tower with Heat Storage

A solar thermal power station is much like a coal,natural gas or even nuclear power station once the source of heat has been established. Of course if we consider emissions or safety for each of these options Solar Thermal is the clear winner.  For the Solar Thermal power plant the source of heat is the sun.

 

Molten salt is used to collect and store the sun’s energy as heat. Cold salt at 290 degree C, is pumped from the cold salt tank up the tower to the collector where it is heated to around 600 degrees C. It then descends to the hot salt tank where the heat can be stored for use during the night or pass on to the boiler for immediate use.
