Industrial CO 2 emission mitigation necessitates holistic technology concepts; especially in high-emission industrial sectors like the iron and steel industry. A novel direct reduction technology with hydrogen reduces CO 2 emissions in iron production from siderite ore by more than 60 %. Subsequent valorization of the process gas, consisting of unconverted hydrogen, carbon monoxide, and CO 2, by catalytic hydrogenation to methane and methanol completes the technology concept. This route gives access to CO 2 emission-lean iron production from siderite ore, fossil-free methane and methanol synthesis, and thus, improved energy density of the energy carrier hydrogen.
