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

    University essay from KTH/Materialvetenskap

    Author : Moa Bertling; Agnes Milstig; [2022]
    Keywords : ;

    Abstract : 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.
