The study includes 4 types of PtG (PtH2, PtSNG using pure CO2, PtSNG using treated BFG, and PtSNG using BFG), two types of blast furnaces (air-blown and oxygen) and two types of fossil replacement (coal or coke). The blast furnaces are modelled using the Rist diagram, validated with literature data (<2% deviation). For most cases, the decrease in total CO2 emissions is around 150–215 kgCO2/tHM per MW/(tHM/h) of electrolysis. The energy penalty (in terms of electricity consumption) was found to be mostly independent on the size of the PtG plant, but greatly dependent on the type of integration (10.1–20.6 MJ/kgCO2). If significant CO2 reductions are aimed, self-sufficiency in electricity consumption will not be achieved. In practice, the maximum PtG capacity to install is limited by the decrease in the flame temperature. In this context, the PtSNG integration consuming treated BFG, applied to OBF for coal replacement, provides the best results. Assuming a 500 tHM/h blast furnace, the PtG capacity of this concept could be as large as 490 MW and avoid up to 21% of the CO2 emissions. info:eu-repo/grantAgreement/EC/H2020/887077/EU/Decarbonisation of carbon-intensive industries (Iron and Steel Industries) through Power to gas and Oxy-fuel combustion/DISIPO This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 887077-DISIPO info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 11.1 2022 ENGINEERING, ENVIRONMENTAL 8 / 55 = 0.145 2022 Q1 T1 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 8 / 46 = 0.174 2022 Q1 T1 ENVIRONMENTAL SCIENCES 22 / 275 = 0.08 2022 Q1 T1 1.981 2022 Environmental Science (miscellaneous) 2022 Q1 Strategy and Management 2022 Q1 Renewable Energy, Sustainability and the Environment 2022 Q1 Industrial and Manufacturing Engineering 2022 Q1 18.5 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Nakagaki, Takao Kataoka, Ryoma 5004 590 Universidad de Zaragoza Dpto.
