Surface water TES system honored

Ben Welter - Wednesday, December 10, 2014

IF Technology of the Netherlands has received a Sustainable Urban Delta Award for its innovative thermal energy storage system for a residential complex in Wageningen. The system takes advantage of temperature differences in surface water near the complex. In summer, for example, warm water is stored in an aquifer thermal storage system that helps heat the complex in winter. Overall, the system is said to be 25 percent more efficient than a conventional seasonal TES system.

The Delta Award recognizes Dutch companies that offer innovative solutions to the climate-change challenges faced by cities in low-lying, densely populated coastal areas with large river estuaries.

New database to help PCM selection in construction

Ben Welter - Friday, December 05, 2014

Using CES Selector software, researchers in Spain have created a database of phase change materials to help engineers select the right PCM for thermal energy storage in buildings. More than 300 PCMs have been entered in the database, noting thermophysical properties such as melting temperature and melting enthalpy.

According to an abstract of the research reported in Volume 57 of Energy Procedia: "This database can be completed in the future with other relevant properties ... such as chemical properties (durability in different media etc), reported density or viscosity at a given temperature or even cost of each material."

The full report, "New database on phase change materials for thermal energy storage in buildings to help PCM selection," is available via ScienceDirect.

Ice Energy wins innovation award for TES system

Ben Welter - Thursday, November 20, 2014

Ice Energy of Glendale, Calif., has won a Los Angeles Business Journal 2014 Patrick Soon-Shiong Innovation Award. The company, which makes the Ice Bear thermal energy storage system, was honored as one of the region's "most impactful innovators." The Ice Bear system makes ice at night, when electricity is cheaper, and uses it to cool buildings during the day.

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.
