1. A power plant system, comprising:
a single solid oxide fuel cell and a gas turbine,
wherein the single solid oxide fuel cell and the gas turbine are set up such that compressed charge air of a compressor of the gas turbine is provided to the solid oxide fuel cell and/or an exhaust gas of the solid oxide fuel cell is provided to a combustion chamber of the gas turbine,
wherein the power plant system is configured such that the single solid oxide fuel cell is operated in a load or cell mode as well as in an electrolysis mode and wherein the single solid oxide fuel cell is set up such that an excess grid energy is used for executing an electrolysis in the electrolysis mode of the solid oxide fuel cell and thereby to chemically reduce water and/or carbon dioxide into hydrogen and/or syngas.
