Electrified Reforming of Biogas to Hydrogen for Industrial Furnaces with Negative Carbon Emissions: A Feasibility Study

Sammanfattning: The steel industry emits large amounts of carbon dioxide, the main emissions are produced inthe process of heating up steel in industrial furnaces of electric arc furnaces (EAF). The purposeof this project was to propose and evaluate a process of reforming biogas to hydrogen to use asfuel for industrial furnaces and result in carbon neutral or carbon negative emissions. This hasbeen done through a literature study reviewing current methods of reforming biogas to hydrogengas, computer simulations in a program called Aspen Plus, thermodynamic calculations and acomparison with the combustion of pure methane. The study resulted in a process theoreticallypossible which would produce negative carbon emissions as a result of carbon capture andstorage techniques. The proposed process is not as efficient as the process of burning puremethane, however, because it can offer carbon negative emissions it is still a more beneficialoption environmentally.
