Abstract: The invention relates to a hydrogen storage power plant (1) comprising: in order to produce hydrogen (H2) from methane or natural gas, a pyrolysis device for methane pyrolysis and/or natural gas pyrolysis and/or a plasmalysis device (6) for methane plasmalysis and/or natural gas plasmalysis; -a storage device (11), which is coupled on the output side to the pyrolysis device, for storing the hydrogen (H2) or a storage device (11), which is coupled on the output side to the plasmalysis device (6), for storing the hydrogen (H2); and a hydrogen combustion engine (12) which is coupled on the outlet side to the storage device (11) and has a closed noble gas circuit (12.1) for circulating noble gas, which noble gas circuit leads from an outlet channel (12.2) of the hydrogen combustion engine (12) via a circulation path to an inlet channel (12.3) of the hydrogen combustion engine (12) and guides a noble gas (EG) from the outlet channel (12.2) via the inlet channel (12.
