CSP technology employs mirrors that concentrate reflected sunlight onto receivers containing heat transfer fluids. From there, the fluids are used to heat water, which in turn generates steam that is used to power turbines and produce electricity. By adding thermal storage to these facilities they are able to operate at significantly higher capacity factors and produce approximately double the energy for the same size power facility. Furthermore, the production of electricity can be shifted to occur at the same time as peak power demand, making the electricity much more valuable.
"Utilizing these low-cost regenerative calcium-based sorbents, researched for carbon dioxide capture in coal-based power generation facilities, leverages existing knowledge bases and is an innovative transfer of technology," said Dr.
Furthermore, while molten salt storage systems can only operate up to about 550 degrees Celsius, the Southern Research Institute TCES system can operate sustainably up to 900 degrees. "As the next generation of CSP plants moves towards higher operating temperatures to achieve higher conversion efficiencies, a new generation of high-temperature storage needs to be developed to allow these facilities to continue to provide power in a cost-effective and dispatchable manner," said
