Simulation of +ydrogen 8sage in (lectric $rc)urnace for,ts 'ecarbonization

Electric steelworks are spending relevant efforts to improve sustainability by confirming its fundamental role in the transition towards climate-neutral steel production. The substitution of fossil carbon with alternative carbon sources and the use of green hydrogen for heating purposes in electric arc furnaces are some of the investigated aspects in the GreenHeatEAF European project. In this paper, an electric steelworks flowsheet model is presented and simulations results concerning the effects of hydrogen use (alone or as a blend with natural gas) are discussed. The coupling with a PEM electrolyzer model allows computing the electric requirements in each analyzed case.
