As the world is experiencing a period of imminent threat owing to climate change, the steel industry is also facing a tremendous challenge in next decades. This themed issue makes a survey on the current situation of steel production, energy consumption, and CO2 emissions, as well as cross-sections of the potential methods to decrease CO2 emissions in current processes via improved energy and materials efficiency, increasing recycling, utilizing alternative energy sources, and adopting CO2 capture and storage. The current state, problems and plans in the two biggest steel producing countries, China and India are introduced. Generally contemplating, incremental improvements in current processes play a key role in rapid mitigation of specific emissions, but finally they are insufficient when striving for carbon neutral production in the long run. Then hydrogen and electrification are the apparent solutions also to iron and steel production. The book gives a holistic overview of the current situation and challenges, and an inclusive compilation of the potential technologies and solutions for the global CO2 emissions problem.Technology: general issuesbicsscalternate ironmaking processesblue dustby-productscarbon capture and storagecarbon emissioncarbon emissionscarbon footprintcharcoalcircular economyclimate changeclimate warmingCO2 mineralizationCO2 mitigationcoking coaldecarbonizationdigital skillsdigital technologiesdigital transformationdigitalizationdirect reductionDRIecology transitionelectricity generationemissions mitigationenergy consumptionenergy savingenvironmentenvironmental impactflash ironmaking processfossil-free steelgas injectiongrid balancinghydrogenhydrogen direct-reduced iron (H2DRI)hydrogen in steelmakinghydrogen production by water electrolysishydrogen storageindustrial restructuringindustrial symbiosisiron oreiron ore concentrateironmakingkinetic modelskineticslean and frugal designlife cycle assessment (LCA)mathematical modelmelting of H2DRI in EAF (Electric Arc Furnace)metallic productsmetalsmini blast furnaceminingn/ananoparticlesnatural gaspollutionproductionrecyclingrenewable electricityreusescrapself-reducing burdensmelting reductionsteelsteel industrysteel visionsteelmaking slagstechnology upgradetoxicologyTechnology: general issuesHolappa Lauriedt1303450Holappa LauriothBOOK9910557390103321Challenges and Prospects of Steelmaking Towards the Year 20503027060UNINA
