Abstract (en)

[origin: WO2021219854A1] The invention relates to an underwater pumped-storage power plant reservoir in a dry but floodable ground depression, in particular in an open-cast mine that is disused or still in operation, the reservoir comprising: a modular arrangement of a plurality of individual pressure vessel modules for the intermediate storage of electrical energy from other power plants, in particular wind power stations and/or photovoltaic installations, wherein the pressure vessel modules each have an outer wall comprising at least one through-flow opening for the inlet and/or outlet of water such that the pressure vessel modules can each be independently filled with water and/or pumped dry if the dry ground depression is flooded with water, and wherein the modular arrangement of the pressure vessel modules is designed such that the pressure vessel modules are arranged in the dry but floodable ground depression so as to be adjacent, in particular without any gaps, relative to one another, with their outer walls flat against one another.
