| Abstract Scope |
The competitiveness of steel products in the marketplace will shift according to individual manufacturers’ ability to cost effectively reduce CO2 emissions as measured by cradle-to-gate Life Cycle Analysis (LCA). This study was performed by using LCA and cost estimate research to compare the CO2 emissions and the additional cost applied to the production of various decarbonized materials used in sheet for automotive industry applications using the bending stiffness-based weight reduction factor. The paper discusses the future costs scenarios based on carbon taxes and hydrogen cost. The pathways to decarbonize steel in comparison to alternative materials such as aluminum and reinforced polymer composites were evaluated. Normalized global warming potential (nGWP) estimates were calculated assuming inputs from the current USA electricity grid, and a hypothetical renewable-based grid. From the cost point of view, the current cheapest decarbonized production routes are was identified and discussed further. |
