Ice Energy plans to begin marketing "Solar + Ice," a combined photovoltaic and thermal energy storage system.
The company's behind-the-meter Ice Bear system stores thermal energy in the form of ice at night, when demand for power is low. The combined system uses excess solar energy to create ice during the day, with the Ice Bear providing cooling in late afternoon and early evening hours as solar generation tapers off.
The Santa Barbara, Calif., company says it is partnering with leading solar companies such as NRG Energy on the new system. It will be available to utilities through long-term power purchase agreements that guarantee performance.
“Solar has proven itself to be a low-cost, reliable and green generation resource, but its intermittent nature has limited its value to the grid,” said CEO Mike Hopkins. “Until now, the missing piece has been cost-effective and reliable storage. Our new bundle solves the problem.”http://www.businesswire.com/news/home/20151014005148/en/Ice-Energy-Launches-Solar-Ice-Greenest-Cost-Effective
