PCM market projected to reach $339 million in the Americas by 2019

Ben Welter - Thursday, April 09, 2015

The market for advanced phase change materials in the Americas will reach $339.56 million by 2019, according to the latest report from MicroMarket Monitor. That's a compound annual growth rate of 19.9% from 2014 to 2019. The report identifies the shipping, packaging and refrigeration segment as a key driver and attributes much of the growth to initiatives by the Emerging Technologies Coordinating Council, the National Renewable Energy Laboratory and other bodies.

MicroMarket Monitor is planning to release similar reports next month on the PCM markets in Asia-Pacific and Middle East-Africa. The Asia-Pacific market is expected to see a compound annual growth rate of 19.2 percent from 2013 to 2018. The Middle East-Africa market is expected see a CAGR of 11.9 percent in the same period.

Steep growth projected for Europe's organic PCM market through 2018

Ben Welter - Wednesday, April 08, 2015

The European market for organic phase change materials is projected to see a compound annual growth rate of 20.4 percent from 2013 to 2018, according to the latest report from MicroMarket Monitor. Organic PCMs fall into two categories: paraffins (derived from petroleum) and fatty acids (derived from animal fat and plant oils). The report, to be released May 2, attributes much of the growth to new government rules aimed at reducing the emission of greenhouse gases.

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:

Ohio teen's PCM proposal wins MIT THINK award

Ben Welter - Monday, March 23, 2015

Aditya JobAn Ohio teen's proposal to use phase change material to improve the efficiency of photovoltaic panels is one of three winners in MIT's annual THINK competition. Aditya Jog, a sophomore at Mason High School near Cincinnati, will receive $2,000 to build his project, a $500 scholarship and project mentorship from MIT students.

"Photovoltaic cells have the potential to utilize the planet’s most plentiful renewable energy source, yet their widespread use has been impeded because of relatively low efficiency," he wrote in his application. "The solar to electrical conversion efficiency of photovoltaic devices suffers when they operate at elevated temperatures. Current solutions rely on active heat dissipation, increasing both capital and operating costs. This proposal offers an alternative, passive heat dissipation system that employs a solid-liquid phase change material as a temperature regulator."

The THINK Scholars Program, sponsored this year by Thomson Reuters, is run by a team of MIT undergraduate students.

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).
