The Roles of Energy and Material Efficiency in Meeting Steel Industry CO2 Targets

摘要: Identifying strategies for reducing greenhouse gas emissions from steel production requires a comprehensive model of the sector but previous work has either failed to consider whole supply chain or considered only subset possible abatement options. In this work, global mass flow analysis is combined with process intensities allow forecasts future under all Scenario shows that capacity primary already near peak and if sectoral are be reduced by 50% 2050, last required blast furnace will built 2020. Emissions reduction targets cannot met energy efficiency alone, deploying material provides sufficient extra potential.
