| 摘要 |
The invention relates to a method and a device, which combine a compressed gas storage having a heat carrier circuit with a hydraulic pressure-maintaining means in such a manner that the gas pressure in the compressed gas reservoir is controlled or can be maintained constant both during storage and removal, thereby allowing a thermodynamically advantageous loading and unloading of the store with gas and the compression and expansion thereof with optimal pressure differences. The heat balance of the heat carrier circuit, preferably with water, is ensured by flash evaporation, which is integrated into the circuit, and a saturated steam turbine plant for current generation. The storage of the feed and return of the heat carrier circuit occurs separately during the pneumatic pressure maintenance. The invention allows the construction of location-independent energy stores at the node points of electrical networks for an on-demand supply of regenerative energy with minimized construction of electrical networks, in particular transmission lines. |
