Abstract [en]
Use of forest biomass as an alternative to fossil fuels and reductants in the different process stages of steelmaking is viewed as a short to medium term solution in tackling CO2 emissions from the steel sector. Judging by the energy intensity of producing steel, the requirement for biomass utilisation is expectedly large. In any case, switching to biomass is met with technical restrictions regarding substitution potentials and feasibility limits. With biomass being a limited and spatially variable resource, the options for localising biomass conversion technologies as well as supplying both the raw material and final product become more complex.In this study, a spatially explicit techno-economic approach is employed to optimize the value chains of certain upgraded biomass products, achieving a least-cost strategy in order to facilitate the adoption of biomass in the steel industry. The impact of localising the production technologies at specific sites is assessed. The scope of the work is limited to the iron and steel sector in Sweden, where ambitious national climate goals for net-zero greenhouse gas emissions are targeted by the year 2045. Results from the optimization model show the plant localisations for biomass conversion, and demonstrate the relationship between plant locations and biomass supply points. The impact of biomass supply for metallurgical purposes is discussed against the backdrop of the existing forest industries.
