Heat is stored in a closed basin having a net inflow of relatively fresher water connected by a strait to a larger body of relatively saltier water by selectively controlling the exchange of water between the body and the basin as a function of the season of the year. In summer, the exchange of water is promoted thereby permitting relatively warmer and saltier water outside the basin to flow through the strait into the depths of the basin. In winter, the exchange of water between the basin and the body of water is suppressed thereby trapping warm, relatively saltier water in the lower regions of the basin, the warm water being available during the winter and being protected against heat loss by a surface layer of relatively fresher water. The heat thus stored can be utilized in various energy conversion processes such as heat pumps to raise the temperature to useful levels. |
