heat batteries

Heat batteries are devices that store thermal energy for later use, much like how electrical batteries store electricity. They work by heating a medium—such as special bricks or liquids—that can retain high temperatures for a long time. When energy is needed, the stored heat is released to generate warmth or power industrial processes. Heat batteries improve energy efficiency, allow for better integration of renewable sources, and help balance supply and demand, making them a valuable tool in sustainable energy systems.
