CRS has a great potential for future electricity production because it can achieve high tem-
peratures in a working uid, which leads to high thermodynamic efciencies of power gen-
eration. Figure 8.30 is a schematic diagram of a CRS with thermal energy storage. Heliostats,
shown in Figure 8.31, direct the sunlight to the receiver on top of the tower. A heat-transfer
uid is pumped through a riser to the receiver where it is heated and then via a downcomer
to the thermal storage unit and/or a heat engine, which is usually located on the ground
near the tower. Typical ...
