The iron and steel industry is the largest energy-consuming sector in the world. It is responsible for emitting 4–5% of the total anthropogenic CO2. As an energy-intensive industry, it is essential that the iron and steel sector accomplishes important carbon emission reduction. Carbon capture is one of the most promising alternatives to achieve this aim. Moreover, if carbon utilization via power-to-gas is integrated with carbon capture, there could be a significant increase in the interest of this alternative in the iron and steel sector. This paper presents several simulations to integrate oxy-fuel processes and power-to-gas in a steel plant, and compares gas productions (coke oven gas, blast furnace gas, and blast oxygen furnace gas), energy requirements, and carbon reduction with a base case in order to obtain the technical feasibility of the proposals. Two different power-to-gas technology implementations were selected, together with the oxy blast furnace and the top gas recycling technologies. These integrations are based on three strategies: (i) converting the blast furnace (BF) process into an oxy-fuel process, (ii) recirculating blast furnace gas (BFG) back to the BF itself, and (iii) using a methanation process to generate CH4 and also introduce it to the BF. Applying these improvements to the steel industry, we achieved reductions in CO2 emissions of up to 8%, and reductions in coal fuel consumption of 12.8%. On the basis of the results, we are able to conclude that the energy required to achieve the above emission savings could be as low as 4.9 MJ/kg CO2 for the second implementation. These values highlight the importance of carrying out future research in the implementation of carbon capture and power-to-gas in the industrial sector.

This article examines the efforts of one British steel company to acquire knowledge about American industrial productivity in the first post-World War II decade. It argues that company information-gathering initiatives in this period were overshadowed by the work of the formal productivity missions of the Marshall Plan era. In particular, it compares the activities of the Steel Company of Wales with the Anglo-American Council on Productivity (AACP), whose iron and steel industry productivity team report was published in 1952. Based on evidence from its business records, this study shows that the Steel Company of Wales was undertaking its own international productivity investigations, which started earlier and were more extensive and differently focused from those of the AACP. It makes the case for viewing companies as active participants in the gathering and dissemination of productivity knowledge in Britain’s steel sector after 1945.

Purpose: To analyse the potential of various scenarios for reduction of carbon footprint of iron and steel sector and to reveal plausible pathways for modernisation. Design/methodology/approach: Several scenarios have been developed in order to assess the dynamics and extent of decarbonisation required to meet the global climate change mitigation target. This includes deployment of the best available technologies, increased share of secondary steel production route and deployment of innovative ironmaking technologies with various decarbonisation extent achieved in a variable timeframe. Findings: The window of opportunities to ensure compliance of steel sector development with climate goal still exists though shrinks. Modernisation shall include global deployment of best available technologies, increased share of secondary steel production and rapid deployment of innovative technologies including carbon capture and storage. Delayed modernisation will require much deeper decarbonisation, which will increase the total cost of mitigation. International policies shall be put in place to ensure availability of funding and to assist technology transfer. Short term transition strategies shall be employed as soon as possible for bridging long term climate change mitigation strategies and current state of the iron and steel industry worldwide. Research limitations/implications: Methodology applied takes into account the best available technologies and some novel ironmaking methods with the potential for commercialisation during the next decade; however, it is implied that the radically innovative iron- and steelmaking technologies with near-zero CO2 emissions will not be mature enough to deliver tangible impact on the sector’s carbon footprint before 2050. Practical implications: Obtained results can be helpful for definition of the modernisation strategies (both state-level and corporate) for the iron and steel industry. Originality/value: Dynamics and extent of decarbonisation required to meet global climate change mitigation targets have been revealed and the results can be valuable for assessment of the consistency of sectoral climate strategies with global targets.

To assess some technologies which are more appropriate for the development of the iron and steel industry in China, a model was developed based on the Long range Energy Alternatives Planning System (LEAP) to assess the energy saving and CO2 reduction potentials from 2010 to 2040. The results show that the top three saving energy potentials is non-blast furnace iron-making accounted for 6.85%, device enlargement for 5.85%, advanced blast furnace for 4.84%, and also show that the top three CO2 reduction potentials is device enlargement accounted for 11.7%, non-blast furnace iron-making for 6.21%, advanced coke and blast furnace 5.52%. In the Mitigation scenario, it can reduce 28% of the initial energy demand and 35.2% of CO2 emissions. It can provide a method and data for search energy saving and CO2 reduction potentials in iron and steel industry by LEAP model.


In India Indian, Iron and Steel Industry plays significantly for the overall growth and development of the country. Based on the budget of Ministry of Steel declares that steel industry contributes 2% of the Indias GDP, and its weight is 6.2% in the Index of Industrial Production(IPP). The sector able to grow by itself globally. In India steel production in one Million Tones in 1947, now its become the world's 2nd largest producer next to China. India's GDP declines 5% in 2019 on account of rising Inflation, GST and strict monetary control. This medium made the domestic demand weeker which grew 3.3% in 2019, Despite the rise in last Quater

The Nigerian iron and steel industry established as a basis for industrialization has remained unproductive even as the year 2020 targeted for the country to become one of the world's top 20 economies is barely a few months away. Despite, the boom in the oil sector, the value-added sector is low while the inter-sectoral linkages are weak. This implies a boom in one activity rarely affects another in the sector, but will rather impact on the foreign economy from where imports were sourced. Nigeria relies mainly on crude oil to the neglect of the iron and steel sector which is a major determinant for the industrialization of any nation. Lack of industrialization and unemployment in Nigeria today which engenders insecurity could be linked to the comatose state of the Nigerian iron and steel industry. Thus, this paper discussed the iron and steel sector as a strategic sector for rapid development and nerve center for industrialization in Nigeria.

Abstract As carbon peaking and carbon neutrality have become a global consensus, more and more countries have introduced relevant policies to adapt to their own countries and formulated corresponding time roadmap. The industrial sector, especially the steel sector, which produces high levels of pollution and carbon emissions, is facing significant pressure to transform its operations to reduce CO2 emissions. Previous studies have shown the importance of financial development (FD) in environmental protection, however, the impact of FD on the CO2 emissions of the steel sector is ignored. This paper examines the impact of FD on the CO2 emissions of the iron and steel industry from a global perspective using comprehensive panel data from a total of 30 countries during the period from 1990 to 2018. Empirical results show that an improved level of FD in a given country reduces the CO2 emissions of the iron and steel industry. Our results also show that the effect of FD on reducing the CO2 emissions of the iron and steel industry in developing countries is less than its effect in developed countries. Estimation results also show the existence of the Environmental Kuznets Curve hypothesis in the iron and steel industry. The mechanism analysis indicates that FD promotes the upgrading of the structure of the iron and steel industry and the reduction of the CO2 emissions by means of the three-stage least square method. Finally, we discuss the policy implications of achieving carbon neutrality in the steel sector.

Based on life cycle assessment, analysis of energy consumption and other environment load by steel production in Chinese typical iron and steel industry was carried out. The process accounted for the most environment load was found by studying the different processes in steel production route. The results indicate that the most important process is blast furnace (BF) which is the major factor of CO2 and CO emissions, and contributes most to globe warming potential (GWP) and photochemical ozone creation potential (POCP).
