Ice Energy’s hybrid AC and energy storage system – the Ice Cub – now available to California homeowners and builders


 Ice Energy, the leading provider of distributed thermal energy storage solutions, today announced that its Ice Cub, an energy-saving hybrid air conditioning and energy storage system, is now available for purchase by California homeowners and homebuilders. The Ice Cub qualifies for the state’s Self-Generation Incentive Program (SGIP) rebate and, for homes with solar PV, the Federal Investment Tax Credit. These two financial benefits effectively reduce the cost of purchase and installation to below that of a conventional air conditioning system.
The Ice Cub is a solar PV-compatible home air conditioning and thermal energy storage system that replaces a conventional 5-ton outdoor condensing unit and works seamlessly with a home’s interior HVAC system. It functions like a typical outdoor condensing unit, cooling the air going into a home to achieve the desired temperature. However, the Ice Cub also has a water tank and heat exchanger, which are used to make and store cooling in the form of ice – enabling it to cool a home for up to 4 hours/day. For homes with solar PV, a full tank of ice can be made and stored during the day, using what would otherwise be surplus solar generation.
“Conventional AC units in California have become increasingly expensive to operate as the state’s new time-of-use rates take effect,” said Joseph Draper, Executive Chairman of Ice Energy. “The Ice Cub, by contrast, reduces consumption of expensive electricity and can save homeowners as much as $1,500 a year on their utility bill. The smart, energy-efficient Ice Cub is a true consumer product with real potential to render conventional home AC units obsolete. We are very excited to make it available for immediate delivery to homeowners and builders here in California.”
