An innovative "ice battery" system is being used to cool buildings and lower energy costs [View all]
https://www.cbsnews.com/news/innovative-ice-battery-system-cool-buildings-lower-energy-costs/New York — In the heart of Manhattan, four stories below ground, the iconic Eleven Madison skyscraper is being air-conditioned using ice.
"There's about 500,000 pounds of ice created every night," said Holly Paeper, president of Trane Technologies Commercial HVAC Americas business, the company responsible for installing the system it calls an ice battery. "And to put that into context, think about three city buses full of ice cubes."
The ice battery system freezes water at night when the cost of electricity is low. Then, during the day, when the price is high, the building is cooled with the previous night's ice instead of using expensive electricity. Trane says that this system can lower cooling costs by up to 40%.
"So, when everyone else is using their electricity in the middle of July to cool their building or to cool their homes, it's a big draw on the grid," Paeper said. "This building won't draw from that because it made its ice last night."
