What is a Sand Battery?
A sand battery is a thermal energy storage system that stores excess renewable energy—primarily from wind or solar—as heat in sand. The sand is heated using renewable sources and retains thermal energy for extended periods, sometimes months. This stored heat can be converted back into electricity or used directly for heating, making sand batteries a versatile solution for energy management.
