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:
