That stored ice is then melted to help cool building temperatures during peak hours. The chemical composition also affects whether ice batteries are compatible with specific types of HVAC systems or heat pumps. Ice batteries could help cool future AI data centersData centers increasingly used to power advanced AI models require massive amounts of electricity. Ice batteries certainly aren’t a silver bullet, but their widespread adoption could help stem the tide of this emerging energy dilemma. If scaled up, they could reduce overall energy consumption, which in turn would lessen the need to build new energy sources.
