Abstract

The invention relates to a process for producing hydrogen, comprising a steam methane reforming (SMR) step for producing synthesis gas, in which heat for the endothermic reaction is at least partially provided by converting electrical energy into heat. The synthesis gas is subject to a water-gas shift step and the shift product is separated into a hydrogen product and a the tail gas. The latter is subject to a tail gas separation step, producing a hydrogen rich stream, a carbon dioxide product, and an off-gas stream rich in carbon monoxide and methane. The hydrogen rich stream is recycled to the shifted synthesis gas. According to the invention, off-gas obtained in the tail gas separation step is recycled to the hydrocarbon containing feedstock stream, so that a combined stream of hydrocarbon containing feedstock, off-gas and steam is supplied to the steam methane reforming (SMR) step.
