    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."

    Review of state advanced energy legislation in 2014

    Ben Welter - Friday, January 02, 2015

    Colorado State University's Center for the New Energy Economy has released a summary of advanced energy legislation passed in U.S. states in 2014. Some 430 advanced energy bills became law, down from 713 in 2013. Changes to renewable portfolio standards were enacted in 12 states, including Maine, South Carolina and Massachusetts.

    Ben Welter - Monday, December 22, 2014

    Luisa Cabeza and Mohammed Farid, two internationally renowned authorities on phase change materials and thermal energy storage, have joined Entropy Solutions’ advisory board.

    Dr. Cabeza, a professor at the University of Lleida, Spain, is the director of GREA Innovació Concurrent, a research group that is developing thermal energy storage concepts and systems for solar water tanks, HVAC systems, industrial applications and concentrated solar power plants. She has co-written more than 100 papers and published several books on phase change material and thermal energy storage.

    Dr. Farid, a professor of chemical and materials engineering at the University of Auckland, New Zealand, is a leading authority on thermal energy storage and phase change materials. He has been working since 1980 on the development of PCMs, their encapsulation and applications, from buildings and cold storage to the cooling of batteries and electronic devices.
