The control of CO2 emissions has become increasingly stringent in the European Union (EU), resulting in EU allowance above 90 €/tCO2. Carbon capture will be required to achieve CO2 emissions control, and carbon utilization via power-to-gas could significantly increase interest in carbon capture in the iron and steel sector. This paper presents a new concept that combines amine scrubbing with power-to-gas to reduce emissions in blast furnace-basic oxygen furnace steelmaking plants. Synthetic natural gas (SNG) is produced using green hydrogen from water electrolysis and CO2 from steelmaking. The synthetic natural gas is later used as a reducing agent in the blast furnace, constantly recycling carbon in a closed loop and avoiding geological storage. The oxygen by-produced via electrolysis eliminates the necessity of an air separation unit. By applying these innovations to steelmaking, a reduction in CO2 emissions of 9.4% is obtained with an energy penalty of 16.2 MJ/kgCO2, and economic costs of 52 €/tHM or 283 €/tCO2. A sensitivity analysis with respect to electricity and the CO2 allowances prices is also performed. 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/grantAgreement/ES/MICINN/PID2021-126164OB-I00/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/UZ/UZ2020-TEC-06 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 9.0 2023 THERMODYNAMICS 3 / 78 = 0.038 2023 Q1 T1 ENERGY & FUELS 24 / 171 = 0.14 2023 Q1 T1 2.11 2023 Electrical and Electronic Engineering 2023 Q1 Energy (miscellaneous) 2023 Q1 Energy Engineering and Power Technology 2023 Q1 Building and Construction 2023 Q1 Civil and Structural Engineering 2023 Q1 Renewable Energy, Sustainability and the Environment 2023 Q1 Industrial and Manufacturing Engineering 2023 Q1 Management, Monitoring, Policy and Law 2023 Q1 Mechanical Engineering 2023 Q1 Modeling and Simulation 2023 Q1 Pollution 2023 Q1 Fuel Technology 2023 Q1 15.3 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Bailera, Manuel Universidad de Zaragoza (orcid)0000-0002-9174-9820 Peña, Begoña Universidad de Zaragoza (orcid)0000-0001-9967-5806 Romeo, Luis M.
