  • 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.

    PureTemp 23 shows no corrosive effect on five metals tested in study

    Ben Welter - Friday, December 26, 2014

    PureTemp 23, one of 19 PureTemp phase change materials recently certified as 100 percent biobased by the U.S. Department of Agriculture, has been shown to have no corrosive effect on metals tested in a study by researchers from the University of Barcelona and the University of Lleida in Spain. The five metals tested were aluminum, copper, carbon steel, stainless steel 304 or stainless steel 316.

    Global demand for PCMs projected to hit $1.47 billion by 2019

    Ben Welter - Monday, December 15, 2014

    The global demand for advanced phase change materials is expected to reach $1.47 billion by 2019. The latest research report on the industry by Markets and Markets attributes the growth to increasing demand for advanced PCM in several areas, including thermal energy storage, building/construction, HVAC, cold chain, shipping, packaging/transportation, textiles and electronics.

    The main types of advanced PCMs are salt hydrates, paraffins and biobased compounds. "Biobased PCM is estimated to have the highest CAGR from 2014 to 2019," the report said. "Prices of biobased PCM are also likely to fall significantly during the same period."

    30.5% growth projected for biobased PCM market in Europe

    Ben Welter - Wednesday, November 19, 2014

    MicroMarket Monitor is projecting that Europe's biobased advanced phase change material market will reach $46.4 million in four years. "The market is expected to grow at a CAGR of 30.5% from 2013 to 2018," according to the report, scheduled for release Dec. 8. MicroMarket attributes the growth to demand for eco-friendly HVAC applications and "cost-effective prices" of biobased PCMs.

    BioPCM featured in case study of Australian home

    Ben Welter - Tuesday, November 18, 2014

    Phase Change Energy Solutions' BioPCM is being used in the upstairs walls of a house in Victoria, Australia.  “Everything is effectively the same as a reverse brick veneer system," said Jeremy Spencer, director of the Melbourne firm that designed the house. "But instead of bricks we have the phase change material that sits inside the cavity and behind plasterboard internal wall." The project is profiled in InfoLink, "Australia's Architecture, Building, Construction and Design Directory." 

    Forbes interview with Jane Chen, Embrace co-founder

    Jane Chen"The Embrace warmer has now saved over 100,000 infants across nine countries," Jane Chen tells Forbes magazine. "We’ve gotten support from Beyoncé, who made a gift in the amount of $125,000 to Millenium Promise to bring Embrace infant warmers to 100 rural health facilities in sub-Saharan Africa. Marc Benioff, chairman and CEO of salesforce.com, recently made an investment into Embrace Innovations, our for-profit social enterprise arm."
