Buildings are turning to 'ice batteries' for sustainable air conditioning 8 mins ago Buildings in the U.S. are turning to ice batteries for air conditioning — a technology that freezes water into ice at night when electricity is cheap and lets it thaw during the day to cool indoor spaces. Experts say it reduces emissions and strain on the grid and lowers electricity demand. With warming temperatures, rising electricity costs and growing energy demands, especially from data centers, ice thermal energy storage is gaining attention as a sustainable and cost-effective solution for air conditioning. Norton Audubon Hospital in Louisville, Kentucky said it saved $278,000 during the first year their ice energy system went into operation.
