System and method for storing hydrogen obtained from coal

摘要

A system (10) for storing hydrogen obtained from coal is described, comprising a coal gasification reactor (22) for gasifying the coal, a steam power plant (24) for electricity production, which is thermally coupled to the coal gasification reactor (22), a water gas shift Reaction plant (26) connected to the coal gasification reactor (22) for receiving the reaction gases from the coal gasification reactor (22). In addition, the system (10) comprises a discharge line (34) which is coupled to an output (32) of the water-gas shift reaction system (26) and which is thermally coupled to a feed water line (36) of the steam power plant (24), and a gas reservoir (28) ), wherein the gas storage (28) is connected to the water-gas shift reaction system (26) in order to store at least one of the product gases of the water-gas shift reaction system (26). A method for storing hydrogen obtained from coal is also described.
