In a steam generation system (17) comprising a high-temperature heat pump (1) with a heat-carrier fluid circuit (4), in which a heat energy feed-in device (8) coupling heat energy into the heat-carrier fluid of the heat-carrier fluid circuit (4) and a heat energy discharge device (6) coupling heat energy out of the heat-carrier fluid of the heat-carrier fluid circuit (4) are arranged, as well as a compressor (5) or compactor, and an expander (7) or an expansion turbine or a throttle (7a) or a screw expander, a solution is provided which enables the generation of steam from local heat, in particular heat from a district heating supply network and/or waste heat from an industrial process, and supplied electric current. This is achieved in that, in the heat energy feed-in device (8), heat energy coupled out of an inflowing temperature-controlled fluid flow (9) and transferred to the heat-carrier fluid of the heat-carrier fluid circuit (4) heats the heat-carrier fluid, and the compressor (5) or compactor compresses this heated heat-carrier fluid prior to its entry into the heat energy discharge device (6) to such a pressure that the heat energy thereof, coupled out of the heat-carrier fluid in the heat energy discharge device (6) and transferred to the water (10), in particular feed water, flowing through the heat energy discharge device (6), vaporizes the water (10), in particular the feed water.
