Ice-based technology promises lower energy usage

City and utility officials throughout Southern California are eyeing a new system that relies on ice to store energy for air conditioners as a possible way to cut peak commercial consumption and reduce the threat of crippling blackouts. The system developed by Ice Energy Inc. consists of a large plastic attachment for commercial air conditioning units that is filled with water, frozen overnight, then used to cool refrigerant during the day.”It stores energy at night, when energy is cleaner to produce, cheaper to buy and easier to obtain, and it makes it available for use during the day,” said Frank Ramirez, CEO of Ice Energy, based in Windsor, Colo.
