SUMMARY:Hydrogen based direct reduction for CO2-lean steelmaking 
DESCRIPTION:The iron and steel industry accounts for approximately one-quarter of the global industrial CO2-emissions. As the reduction potentials of the current steelmaking routes are rather low, the transfer towards breakthrough-technologies is essential to achieve the climate neutrality by 2050, in line with the European Green Deal. The hydrogen-based direct reduction in combination with an electric arc furnace is one of the most energy efficient approaches to accomplish a CO2-lean steelmaking process. Therefore, the state-of-the-art natural gas based direct reduction acts as a basis for the first step of this transition. This process is already operated with a syngas containing CO and H2 produced out of natural gas. The high flexibility of the DR-route allows the gradual substitution of natural gas by hydrogen and, in a long-term view, running the process with pure hydrogen.
The aim of this work is the analysis of the hydrogen-based direct reduction process from a technical and economical point of view. The results obtained; as the energy- and reactants demand, CO2 reduction potentials and production costs; were compared with the blast furnace and direct reduction process with natural gas, considered respectively as the reference- and the bridge technology route between both processes. The techno-economic assessment performed here, conforms the basis for the roll-out plan on behalf of the decarbonization of the steel industry
