Invitation: Opening of the direct reduction plant for …
hydrogen reacts completely with the oxygen in the iron ore and converts it into elemental iron ("Direct reduced iron" (DRI)). Instead of carbon dioxide, this technology produces only water vapor, which can be used again for hydrogen production. This water cycle represents a further decisive advantage on the way to sustainable iron production.
