Meet Ice Cub: a nifty new home energy storage device and HVAC system

Ice CubIce Energy, a leading provider of distributed thermal energy storage solutions, has launched the Ice Cub – a reimagined way to cool and heat the home, store energy and optimize solar PV. Building upon Ice Energy’s patented thermal energy storage and load management technology, the Ice Cub is designed to provide homeowners with affordable, reliable and eco-friendly heating, cooling and energy storage system available.

The Ice Cub is a compact, home-optimized HVAC system comprised of an ultra-high efficiency compressor and ice tank with heat exchanger. The compressor operates in multiple modes; it can cool the home like a conventional AC unit or, alternatively, it can store energy in the form of cooling by freezing water in the ice tank. When the latter process is complete, the compressor can be shut off and, without using any electricity to create cooling, the ice battery will provide up to four hours of cooling to an entire home. Further, when heating is required, the circuit reverses and the compressor operates as a heat pump to provide all the heating required for a home.

The Ice Cub’s energy storage capabilities make it ideal for homes with solar PV. With a charge time of just four hours, the Ice Cub can utilize solar over-generation to fully charge without using any energy from the grid. The ice tank can also be charged overnight, when electricity is cheapest, to provide cooling in the morning before solar power is available. Thus, the Ice Cub’s storage can be fully charged and discharged twice a day, and there is no degradation over its operating life.

“The Ice Cub is a truly disruptive consumer HVAC solution,” said Mike Hopkins, CEO of Ice Energy. “It will change the way people think about cooling and heating, and how they consider energy storage for their home. It enables homeowners to take charge and save on their utility bill, get the most from their solar PV, and reduce CO2 emissions by up to 1,000 pounds per year.”

Ice Cub product testing was successfully completed in October. The first production unit will be installed in early December and the product will be available for purchase in early 2017. Additionally, as an advanced energy storage system, California residents are eligible for the Self-Generation Incentive Program (SGIP), which can reduce Ice Cub costs to less than those of a conventional high-efficiency AC unit.

To date, more than 1,000 Ice Bear 30 and Ice Bear 20 systems have been installed in over 40 utility service territories nationwide, surpassing 35 million hours of reliable, energy-saving operation.

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We discuss everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
