Power generating station with a high-temperature reactor, a steam power generating station connected to the high-temperature reactor, a plant for generating hydrogen from carbon-containing material, with a coal gasifier for the hydrogenating coal gasification, a gas purification plant connected to the gas stream of the coal gasifier, a low-temperature gas separation plant following the gas purification and a tube cracking furnace which is connected to the methane line of this gas decomposition plant heated by the heat transporting medium of the high-temperature reactor for cracking a methane/steam mixture, and with a gas processing plant which is connected to the exhaust gas line of the tube cracking furnace and consists of at least one heat exchanger, a converting plant and a carbon dioxide scrubber. The residual coke of the coal gasifier is fed to an iron bath gasifier and the exhaust gas of the iron bath gasifier is fed, via a heat exchanger plant together with a part of the hydrogen gas leaving the gas processing plant following the tube cracking oven, to a plant for producing chemical raw material.
