Outlast introduces new PCM-based filler material

Ben Welter - Friday, November 14, 2014

Outlast Technologies’ new Universe climate-control material is designed for use in bedding and apparel. The material is a combination of 70 percent down and 70 PCM-laden viscose fibers. Thicker fibers carry a greater amount of phase change material. “The performance compared to a standard PCM viscose fibre here is four times higher,” says Martin Bentz, managing director of Outlast Europe.

New book on thermal energy storage and sustainability

Ben Welter - Friday, November 07, 2014

TES book cover"Thermal Energy Storage Technologies for Sustainability," a new book by S. Kalaiselvam and R. Parameshwaran of Anna University in Chennai, India, details the latest thinking on latent, sensible and thermo-chemical energy storage systems and their applications across industries. The authors discuss the use of phase change materials and provide case studies of several systems in use. Published by Academic Press in August 2014.

Ice Energy lands 16 contracts with Southern California Edison

Ben Welter - Thursday, November 06, 2014

Ice Energy has been awarded sixteen contracts from Southern California Edison to provide 25.6 megawatts of behind-the-meter thermal energy storage using Ice Energy’s Ice Bear system. The TES system attaches to one or more standard 5- to 20-ton commercial AC units. The system makes ice at night when demand for electricity is low and capacity is abundant and increasingly sourced from wind and other renewables. During the day, the stored ice is used to provide cooling.

The science of phase change: It’s (more) complicated

Ben Welter - Thursday, November 06, 2014

Think you know how phase change works? You might need to rethink that. Researchers at Princeton, Peking University and New York University say the process is a lot more complex than previously known. "This research shows that phase changes can follow multiple pathways, which is counter to what we've previously known," explains Mark Tuckerman, a professor of chemistry and applied mathematics at NYU and one of the study's co-authors. "This means the simple theories about phase transitions that we teach in classes are just not right."
