Abstract

A method and system are presented for storing solar collected heat and using the stored heat to produce power. The method includes diverting solar heated fluid at a temperature greater than a power plant block (PPB) temperature from a heat transfer circuit to a liquid water storage medium maintained at a temperature less than the PPB temperature and thermally storing the heated portion; and transferring heat from the liquid water storage medium to a fluid during periods of decreased solar radiation levels to produce power by the heatedtransfer fluid. The solar thermal storage system includes a hot water storage medium (HWSM), a cold water storage medium (CWSM), conduit means interconnecting the HWSM and said CWSM, and a storage medium heat exchanger for heating water flowing from the CWSM to the HWSM when the solar radiation is above a nominal value to establish a power plant block (PPB) temperature.
