Solar-powered thermal batteries release heat on demand
If successfully scaled for commercial use, a new thermal battery that has been developed by researchers from the University of Massachusetts Amherst could revolutionize the way heat is accessed in rural and off-grid locations. Made from a chemical composite called AzoPMA that combines fatty acids with a light-activated compound, the new phase change material does away with the need for extensive, and expensive, insulation. Most phase change materials lose heat quickly and unpredictably after being altered.
