The invention relates to a pumped-storage power plant type (1) which is set up predominantly in seas. The core of the storage power plant comprises vertically superimposed chambers (2, 3), with which "filling and emptying processes" of the water medium can be effected in order to create potential energy or a head, and to produce electricity therefrom. The upper chambers (2) are connected to the lower chambers via controllable flow channels (4), through which water turbines (10) in the lower chambers (3) can be impinged upon to drive electrical generators (ll) for outputting electrical energy in the form of current. The store is filled in that water pumps (12) driven by electric motors (13) pump water from the lower chambers (3) into the sea, whereby the conversion into potential energy of the water in the upper store is effected from the supplied current for storing the electric energy, minus efficiency losses, for the water pumps. The pumped-storage power plants in the sea preferably offer the necessary storage capabilities for alternative power plants such as wind farms or solar farms of all types, without having to consider shortages of water medium. |
