ABSTRACT:
"This document looks at performance improvement and availability of enhancement of solar thermal power plants by means of high temperature thermal energy storage. The use of the sun's radiation to cover man's energy needs has two basic advantages over the fossil or nuclear conversion

techniques: It is renewable - no raw materials are consumed and it is clean -no pollutants or radiation can be emitted. However, nature does not provide these advantages for free. In order to make use of them, solar engineers must overcome the inherent drawbacks of solar radiation: It's low power density and it's intermittent supply. Both properties conflict with currently available conversion techniques which require a constant high power supply for economical operation. To achieve immediate high power levels, solar energy must be integrated over large surfaces, concentrated to the desired power level and then delivered to the consumer at the place and time desired. These two basic functions, energy storage and energy transport determine the choice of the energy conversion system and the energy carrier used. In solar plants, the seasonal solar radiation supply is distributed to seasonal loads through long term storage, while short term storage is required for evening out the daily intermittent flux conditions, prolong operation after sunset and shift energy sales from low revenue off-peak hours to high revenue peak demand hours.
