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:
