The iron and steel industry is one of the largest emitters of greenhouse gases in the world today. The current annual steel production of around two billion tonnes is constantly increasing. As an indispensable material in the construction of infrastructure, steel will experience a significant upswing in the coming decades, especially in the current newly industrialising countries. In view of the impending climate crisis, it is absolutely essential to push ahead with the decarbonisation of steel production as quickly as possible. Hydrogen reduction has been a key technology in this context for years. This short project deals with relevant aspects relating to the reduction of iron ore with hydrogen. How much energy is required to produce the necessary hydrogen and can this be provided by renewable energies, for example in Austria? What difficulties are to be expected in the conversion of an integrated iron and steel works and how can these be overcome? What is the impact of the elimination of blast furnace slag as a feedstock in the cement industry? These and other aspects are dealt with conceptually.
