Simulation of Integrated Steel Works Transitional Pathways Toward H2-DRI-Based Route

Integrated steelworks transition towards hydrogen-direct reduction iron-based route is considered a promising solution for the decarbonization. However, it foresees the introduction of new units in facilities currently optimized from the point of view of the production and from the gas and energy management. The contribution focuses on the use of a module of a simulation toolkit for first stationary simulations of transitional pathways starting from a European integrated Standardized Steel Mill. The effects of the introduction of direct reduction processes and of different shares of hydrogen in reducing gas in the shaft furnace on gas and energy management are investigated.
