High growth in PCM demand seen for shipping, transportation, textiles, electronics

Ben Welter - Tuesday, January 13, 2015

Companies and Markets is projecting that demand for advanced phase change material will reach $1.4 billion by 2019. Europe will remain the largest market, followed by the Americas. 

"Building & construction is the major application for the advanced PCM market," the report said. "It accounted for 20% of the market share in terms of volume, in 2013. Shipping, packaging & transportation, textiles, and electronic applications of advanced PCM are projected to experience high growth among the applications between 2014 and 2019."

    20% CAGR projected for advanced PCMs

    Ben Welter - Wednesday, January 07, 2015

    The global market for advanced PCMs is projected to reach $1.47 billion by 2019, according to ReportsnReports.com. That's a compound annual growth rate of more than 20 percent over the next five years. The market for thermal energy storage PCMs is projected to register a CAGR of 22 percent in that period.

    "Organic PCM are projected to have the higher growth rate than inorganic PCM due to the higher prices and ease of microencapsulation for organic PCM," according to the report.

    10 strategies for sustainable lab design

    Ben Welter - Tuesday, January 06, 2015

    Blake Jackson and Stephen Palumbo of Tsoi/Kobus and Associates and Jacob Knowles of BR+A Consulting Engineers offer "10 practical strategies to help guide decision-making to further elevate sustainable laboratory design, regarding resource utilization, carbon footprint and long-term viability." Strategy No. 1: Reduce lighting power densities. The authors note that building codes are lowering LPD thresholds, thanks to the availability of cheaper and more energy-efficient LEDs for ambient and task lighting.

    Gibson wireless headphones feature Outlast PCM

    Ben Welter - Tuesday, January 06, 2015

    Gibson Trainer headphonesGuitar-maker Gibson has entered the headphone market with a bluetooth model designed with help from Olympic champion sprinter Usain Bolt. The Trainer, geared toward athletes, employs Outlast phase change material to keep the ear pads at a comfortable temperature. The weather- and sweat-resistant headphones are expected to be available in April with a retail price of $239.

    CSP storage system has theoretical thermal efficiency of more than 74%

    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.
