    Ben Welter - Monday, January 05, 2015

    Using a novel modeling tool for concentrated solar power, Spanish researchers have designed a more efficient storage system employing multilayered phase change material. The CSP system has a theoretical thermal efficiency of more than 74 percent and requires only a third of the molten salt needed in traditional two-tank systems.

    The system was first described in "A New Thermocline-PCM Thermal Storage Concept for CSP Plants. Numerical Analysis and Perspectives," a paper presented at SolarPACES 2013. "The key aspect of this new concept," the researchers wrote, "is the inclusion of PCM layers at both ends of the tank, whose fusion temperatures are conveniently chosen to be inside the 'admissible' temperature ranges for the outlet of both charge and discharge processes."
