DoE Creates Thermal Storage System for Nighttime Solar Use: Page 2 of 2

a full-scale system that is made of many modules stacked or organized together,” he said. “Therefore, the performance characteristics we will measure from testing the pilot can directly reflect those of a power-plant system.”

Researchers expect that the full-scale design will meet the needs of current power plants that operate steam turbines at about 850F to 1,100F using magnesium chloride as the storage medium, researchers said. The design also should scale up using sodium chloride when advanced super-critical carbon dioxide turbines -- which are more efficient but operate at a hotter 1,300F -- come into use, they said.
