Abstract
In order to improve a heat storage system, comprising a heat source, a heat storage device and a heat sink, between which heat is transferred by means of a heat transporting medium, such that a steam-powered engine which is to be operated with overcritical steam of the heat transporting medium can be operated with an inexpensive and simple construction of the heat storage system, it is suggested that the heat sink comprise a steam-powered engine to be operated with overcritical steam of the heat transporting medium, that the heat storage device comprise a Ruths storage device storing the heat transporting medium condensed in the form of a liquid bath and having a storage temperature below the critical temperature of the heat transfer medium and a superheat storage device connected with the Ruths storage device and having a storage temperature above the critical temperature of the heat transporting medium, that the heat storage system be operable during discharge such that in the Ruths storage device steam result from the liquid bath of the heat transporting medium with a temperature corresponding to the storage temperature in the Ruths storage device, and that the steam subsequentl…
