Seasonal heat storage

Seasonal heat storage is a method of capturing excess heat produced during warmer months and storing it for use during colder periods. This process often involves using materials like water or specialized underground cavities that can absorb, contain, and release heat over long periods. For example, solar heat collected in summer can be stored underground and then used to warm buildings in winter, reducing reliance on external energy sources. This approach improves energy efficiency, lowers costs, and promotes sustainability by making renewable heat available year-round.
