Two-tank direct storage was used in early parabolic trough power plants (such as Solar Electric Generating Station I) and at the Solar Two power tower in California. The trough plants used mineral oil as the heat-transfer and storage fluid; Solar Two used molten salt.
In summary, the power tower concentrating solar power plant, at the heart of which lies the heliostat, is a very promising area of renewable energy. Benefits include high optical concentration ratios and operating temperatures, corresponding to high efficiency, and an ability to easily incorporate thermal energy storage.
A thermal energy storage system mainly consists of three parts, the storage medium, heat transfer mechanism and containment system. The thermal energy storage medium stores the thermal energy either in the form of sensible heat, latent heat of fusion or vaporization, or in the form of reversible chemical reactions.
Active two-tank systems The principal elements for a two-tank thermal energy storage system are the material inventory, HTF, heat exchangers and the storage tanks, apart from the storage material circulation pumps. During charging, the amount of heat stored in the fluid depends on the heat supplied by the solar field.
The power tower plant is typically the largest of the CSP designs, consisting of a field of mirrors, heliostats, that track the sun throughout the day and year to maintain a constant focal point on the receiver, which consists of absorber panels of tubes near the top of the tower .
The two existing power tower plants in the United States are in the California/Nevada desert: the Crescent Dunes Solar Energy Project (Figure 5) and Ivanpah Solar Power Facility (Figure 6). Crescent Dunes was designed with a capacity of 110MW and resides on 1,670 acres, including 296 acres of heliostats, each sized 115m2.
