Ice Energy plans to introduce a line of ice-based thermal energy storage systems for the commercial refrigeration market. The new Polar Bear line, under development at the company’s IdeaLAB in Riverside, Calif., is designed for supermarkets and the general commercial refrigeration market.
A variety of Polar Bear models will support a range of storage capacities and application needs. They are expected to be available by the end of this year. No word yet on pricing.
The company says the systems will enable businesses with large refrigeration-based energy loads to reduce their peak electricity demand by up to 95 percent, shifting six hours of a building's refrigeration-based peak load to cheaper off-peak hours.
“The Polar Bear ice battery will seamlessly integrate with existing supermarket or commercial refrigeration systems,” the company said in a press release. “It will also provide a smart-grid controller to monitor energy use and control performance.”
Axiom Exergy and Viking Cold Solutions also offer load-shifting systems for the large-scale refrigeration market. Axiom, of Richmond, Calif., says its saltwater-based “refrigeration battery” can save customers up to 40 percent in energy use during peak hours. Viking, of Houston, Texas, has reported that its PCM-based technology showed reductions in electricity consumption of 30 percent and 39 percent in two low-temperature cold storage facilities in the San Diego area.
