Resumo
THIS ARTICLE EXPLORES THE FUNDAMENTAL ROLE OF THE STEEL INDUSTRY IN GREENHOUSE GAS EMISSIONS AND INVESTIGATES THE POTENTIAL OF REPLACING NATURAL GAS WITH HYDROGEN IN THE MIXED GAS USED AS FUEL IN THE INTEGRATED STEEL PLANTS, CONSIDERING SCENARIOS APPLIED TO A PLANT IN CANADA. AN ITERATIVE OPTIMIZATION APPROACH WAS IMPLEMENTED USING VIRIDIS ENERGY & SUSTAINABILITY, A DIGITAL TOOL FOR ASSESSING THE COST-BENEFIT OF HYDROGEN INTEGRATION. THE STUDY EVALUATES THREE SCENARIOS WITH VARYING NATURAL GAS CONCENTRATIONS, HIGHLIGHTING THE TRADE-OFFS BETWEEN EMISSION REDUCTIONS AND ECONOMIC FEASIBILITY. RESULTS INDICATE THAT HYDROGEN SUBSTITUTION EFFECTIVELY REDUCES CO2 EMISSIONS, BUT IT CONCURRENTLY RAISES FUEL COSTS DUE TO THE EXISTING PRICE DISPARITY BETWEEN HYDROGEN AND NATURAL GAS. HOWEVER, IT IS EXPECTED THAT THE CO2 EMISSION TAX WILL INCREASE OVER TIME, MAKING THIS SUBSTITUTION MORE ADVANTAGEOUS. THE STUDY CONCLUDES THAT HYDROGEN SUBSTITUTION HOLDS PROMISE FOR DECARBONIZING THE STEEL INDUSTRY, DESPITE INCREASED FUEL COSTS, ALONGSIDE THE VALIDATION OF VIRIDIS. HOWEVER, THERE IS A NECESSITY FOR SPECIALIZED BURNERS TO ACCOMMODATE HYDROGEN'S COMBUSTION CHARACTERISTICS AND THE IMPORTANCE OF ROBUST HYDROGEN INFRASTRUCTURE FOR A SUCCESSFUL TRANSITION. CONTINUED ADVANCEMENTS ARE CRUCIAL TO OVERCOME THE CURRENT ECONOMIC BARRIERS AND ENSURE THE LONG-TERM SUSTAINABILITY OF THE STEEL INDUSTRY'S DECARBONIZATION EFFORTS.
