A system includes a combustion power plant for generating power and an electrolysis unit for producing hydrogen. The combustion power plant has a combustion chamber for combustion of a fuel and an offgas conduit for leading off hot offgases formed in the combustion of the fuel. The offgas conduit is thermally coupled to the electrolysis unit. A method for operating the system includes burning the fuel in the combustion power plant, forming the hot offgases in the combustion of the fuel, removing the hot offgases through the offgas conduit, feeding the thermal energy of the hot offgases from the offgas conduit to the electrolysis unit, and producing hydrogen in the electrolysis unit by using the thermal energy from the hot offgases.

A device for preparing a high-voltage direct current transmission includes a first busbar which is connectable to a plurality of first energy generation or consumer units and a second busbar which is connectable to a plurality of second energy generation or consumer units. A transformer system includes a first primary coil which is connectable to the first busbar, a second primary coil which is connectable to the second busbar, and a secondary coil system which is inductively coupled to the first primary coil and the second primary coil to transform power routed on the first and second busbars to increased AC voltage. A converter system is connected to the secondary coil system to convert the increased AC voltage into DC voltage for the high-voltage direct current transmission. A converter station and an energy providing system are also provided.
