Energieübertragungssystem mit einem Phasenwechselmaterial

It is described an energy transfer system (100, 200, 300, 500) for absorbing, temporarily storing and releasing energy. The described energy transfer system (100, 200, 300, 500) comprises (a) a first container (110) containing a Phase Change Material (115), (b) a heat generation element (130), which is connectable to an external energy source (170) and which is capable of charging the Phase Change Material (115) with thermal energy, wherein energy provided by the external energy source (170) is used, and (c) a heat extraction element (140), which is connectable to an external heat engine (180) and which is capable of extracting thermal energy from the Phase Change Material (115), wherein the external heat engine (180) is capable of converting the extracted thermal energy into electric energy. It is further described an energy transfer arrangement comprising two of such energy transfer systems, and a method for absorbing, temporarily storing and releasing energy.
