Connect with PCM experts and industry leaders on LinkedIn

Ben Welter - Wednesday, March 25, 2015

Phase Change Matters logoNew on LinkedIn: A group devoted to the discussion of phase change material and thermal energy storage, a place for PCM and TES experts and industry leaders from around the world to gather and share ideas. It's called Phase Change Matters, and it's intended as a highly interactive complement to the blog and newsletter of the same name.

The first topic up for discussion: PCM and off-peak cooling systems:

TES pioneers like CALMAC and Ice Energy have been installing ice-based energy storage systems for years. And district cooling has been around for decades. What are the main barriers to wider adoption of phase change material in these types of thermal energy storage systems? Complexity? Education? Cost?

You are invited to join the discussion. Here's a link to the group:

Advanced PCM market to hit $1.18 billion by end of 2018

Ben Welter - Tuesday, March 17, 2015

The global market for advanced phase change materials, valued at $350 million in 2011, is expected to reach $1.18 billion by the end of 2018, according to the latest report from Transparency Market Research. That's a compound annual growth rate of 19.5 percent. Europe was the largest market for advanced PCMs in 2011, with the United Kingdom, Germany and France recording the highest demand. Paraffin accounted for more than 50 percent of global demand by revenue that year, followed by salt hydrates (36 percent) and others, including biobased PCMs (12 percent).

Frigesco flash defrost system wins ACR News Award

Ben Welter - Tuesday, March 03, 2015

Frigesco Ltd.'s low-energy flash defrost system was among the winners at last week's ACR News Awards in London, earning Refrigeration Product of the Year honors.

The British company's technology harnesses waste heat to defrost refrigeration systems more efficiently, reducing supermarket cooling costs by up to 20 percent. Phase change material is used to store the waste heat. 

Other ACR winners include Toshiba, Cool Designs Ltd. and Sainsbury Triple Zero Stores.

  • 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.
