The hydrocarbon feed stream is exposed to heat in the absence of oxygen to convert the hydrocarbon feed stream into a solid stream and a gas stream. The gas stream is separated into an off-gas stream and a first hydrogen stream. The carbon is separated from the solids stream to produce a carbon stream. The water stream is electrolyzed to produce an oxygen stream and a second hydrogen stream. Iron ore is reduced to produce iron by flowing hydrogen through the iron ore. The iron and a first portion of the carbon in the carbon stream are combined to produce steel. At least a portion of the oxygen in the oxygen stream and a second portion of the carbon in the carbon stream are combined to produce electrical energy and a carbon dioxide stream.
