SYSTEM FOR STORING AND RECOVERING ENERGY

The invention relates to a system for storing and recovering energy, comprising at least two liquid containers for storing a liquid, the two liquid containers being preferably located at substantially the same level and/or preferably having a substantially identical volume, and a turbine unit for power generation, which connects the two liquid containers to one another and is designed in such a way that the liquid can flow from the one liquid container through the turbine and into the other liquid container and thereby drives the turbine, and a working gas provision unit for providing a working gas, in particular air, having a substantially constant working gas pressure, the working gas provision unit being connected to the two liquid containers and designed in such a way that the working gas having said constant working pressure conveys the liquid from the one liquid container, via the turbine unit and into the other liquid container.
