Thermal storage in ice
Ice is a form of thermal storage, which can help lower the load on the grid during peak times. This is an air conditioner from Ice Energy targeted at commercial and utility customers. At night, it freezes water to make ice and, during the day, it draws on ice to help power the air conditioner. Southern California Public Power Authority signed up to offset enough peak-time electricity to power 10,000 homes.
