Abstract (en)
The invention relates to the production of direct reduced iron, DRI, where a hydrogen direct reduction is synergistically operated in the context of an industrial plant. The hydrogen reduction operates with reducing gas comprising at least 85 vol.% hydrogen, and receives a make-up hydrogen stream. At least part of the make-up hydrogen stream is produced on site. by at least one of (i) electrolysis means configured to produce hydrogen from steam recovered from one or more components of the industrial plant and/or from steam generated using waste heat and/or hot gases emitted by the one or more components; and (ii) gas shift reactor means configured to convert CO-bearing gas emitted by at least one component of the industrial plant into hydrogen and to remove CO<sub>2</sub>.
