Conceptual Design of the Truscott Brine Lake Solar Pond System. Volume II. Utility-Integrated Scenario

摘要

Conceptual designs were developed for salt-gradient solar pond systems to provide pumping power for chloride control in the Red River Basin. Energy is extracted from six, 10.5-ha (26-acre) solar ponds for conversion to electricity using three organic Rankine cycle turbines. The solar pond system is located in a brine impoundment lake at Truscott, Texas. Low-salinity brine flowing into this lake is concentrated by natural evaporation to form the solar pond, and is also used for solar pond maintenance. Two operating scenarios were investigated. A continuous base load system could deliver 9.8 GWh/yr at an output of 1120 kW to the utility electric grid for an estimated capital expenditure of $12.8 million. A system operating only from June through September would cost $21.2 million for an annual energy delivery of 7.7 GWh at a net output during the operating period of 2640 kW. (ERA citation 08:020138)
