A method for producing hydrogen comprises a) performing water electrolysis to produce oxygen and a first hydrogen product stream; b) reforming a hydrocarbon stream with oxygen to produce a reformed stream containing CO<sub>x</sub> and hydrogen; c) optionally, subjecting said reformed stream to a water gas shift process to produce a shifted product stream containing additional hydrogen and carbon dioxide; and separating hydrogen from the shifted product stream to produce a second hydrogen product stream; and d) directing oxygen produced in step a), optionally after buffering, to step b). The method allows for producing constant, continuous and uninterrupted amounts of emission-free hydrogen accomodating external influences such as fluctuations with weather conditions, day-night cycles and seasons.
