In an underground or aboveground device that is a system for heat storage, one or more external vessels contain one or more preferably cylindrical tubular large chambers with water columns, in whose heads superheated steam is generated under pressure and can be fed out to an engine, for example. Piston cylinder sets embedded in the water column can be adjusted when a preset hydraulic pressure of the water column has been exceeded, and compress the gas of their cylinder chamber. A column of pressurised steam is generated in another large vessel. At least one gas expansion circuit, in particular with the medium CO2, is connected to the gas chambers of the cylinder piston sets via a collecting tank and piping. Temperature differences in the water column that are a function of the vertical height are used to control the pressure and temperature of thermal work circuits, and to adjust a float, paddle wheel or the like, of the water column to transfer energy to the outside.
