Nostromo has introduced a new residential, behind the meter, storage system that consists of plain water and a proprietary nucleate.
Called the IceBrick TES (Thermal Energy Storage) cell, the storage system can store and discharge an amount of energy equivalent to 25 kWh of electricity consumed by cooling systems at peak demand hours. The system weighs about 2,000 pounds and measures 20-inch by 20-inch by 157-inches allowing it to be installed on rooftops and along exterior walls.
The IceBrick TES system has no recycling issues and is expected to cost $250 per kWh, reducing the cost per kWh by 80 percent when compared to other ice storage systems, Nostromo claims. The company says the system costs about half as much as a lithium-ion residential battery system while it doesn’t use any rare or poisonous materials.
"The only known and environmentally sustainable way to shift the grid's peak demand from high noon to the dead of the night, is to store energy when there is a surplus in power production capabilities and discharge it when the demand is rising and resources are scarce,” said Yaron Ben-Nun, Founder, and CEO of Nostromo. “With our IceBrick we have redesigned ice storage and are enabling, for the first time, the use of water as a viable energy capacitor for commercial users."
Nostromo will present the ice energy storage system during the Cleantech Forum taking place in San Francisco this week.
