Abstract

According to some embodiments, a process for producing hydrogen may comprise operating an electrolysis cell with a source of electricity to produce an oxygen stream and a hydrogen stream from water, reacting a hydrocarbon feedstock with the oxygen stream to partially oxidize the hydrocarbon feedstock, thereby producing a synthesis gas comprising hydrogen and carbon monoxide; passing the synthesis gas and a water stream to a heat exchanger to produce steam and to cool the synthesis gas; and reacting at least a portion of the synthesis gas from the heat exchanger and at least a portion of the steam from the heat exchanger. The source of electricity to the electrolysis cell for the totality of the operation of the electrolysis cell is not produced from energy provided by the combustion of hydrocarbons;
