Buildings are turning to ‘#IceBatteries’ for #sustainable #AirConditioning
By ISABELLA O’MALLEY
Updated 10:46 AM EST, October 8, 2025"Every night some 74,000 gallons (280,000 liters) of water are frozen at Norton Audubon Hospital in Louisville, Kentucky. The hospital used to get all of its air conditioning from a conventional system found in most U.S. buildings, but now 27 tanks of ice sustain a network of cold-water pipes keeping operating rooms at safe temperatures and patients comfortable.
"This type of thermal energy storage, also known as ice batteries, is being added to buildings in the U.S. for its ability to provide cool air without releasing planet-warming emissions. These systems cut electricity usage and lower the strain on the grid. With rising temperatures and the growing demand for electricity in the U.S., ice thermal energy storage offers a sustainable option for cooling buildings.
"Trane Technologies, a company that makes heating and cooling equipment, says it has seen a growing demand for this technology over the past few years. Its ice batteries are mostly used in schools as well as commercial and government buildings. Nostromo Energy, another company that makes ice batteries, is pursuing customers among energy-intensive data centers that have high cooling demands. Smaller systems are also made for homes by companies such as Ice Energy."

@grzgrz #Geothermal! #Piezoelectric tiles (for cities)! #Flywheels! Also storage solutions like #SandBatteries and #IceBatteries! However, I'm not sure if nuclear fusion fits (have they perfected that yet? What about the waste?).
