“…As far as energy use is concerned, for the present study, the above calculated energy balance for the production of 1 ton of solid steel, amounting to 19.8 GJ, corresponds to a primary energy demand of 23.2 GJ. This last value is in slightly higher than the one calculated by Pardo et al [28] in their study, concerning European steel, which estimates an energy use of 22.5 GJ/ton. Similarly, in the study by Norgate [29], concerning the life cycle energy assessment of steel, the primary energy demand amounts to 22 GJ/ton of steel.…”

Abstract:The purpose of this work is to carry out an accurate and extensive environmental analysis of the steel production occurring in in the largest integrated EU steel mill, located in the city of Taranto in southern Italy. The end goal is that of highlighting the steelworks' main hot spots and identifying potential options for environmental improvement. The development for such an analysis is based on a Life Cycle Assessment (LCA) of steel production with a cradle to casting plant gate approach that covers the stages from raw material extraction to solid steel slab production. The inventory results have highlighted the large solid waste production, especially in terms of slag, which could be reused in other industries as secondary raw materials. Other reuses, in accordance with the circular economy paradigm, could encompass the energy waste involved in the steelmaking process. The most burdening lifecycle phases are the ones linked to blast furnace and coke oven operations. Specifically, the impact categories are influenced by the energy consumption and also by the toxicity of the emissions associated with the lifecycle of steel production. A detailed analysis of the toxicity impacts indicates that LCA is still not perfectly suitable for toxicity assessments and should be coupled with other more site specific studies in order to understand such aspects fully. Overall, the results represent a first step to understanding the current levels of sustainability of the steelworks, which should be used as a starting point for the development both of pollution control measures and of symbiotic waste reutilization scenarios needed to maintain the competitiveness of the industrial plant.

Purpose. Justification of the principles for assessing the competitive status of Ukrainian mining companies' energy efficiency as a derivative of electricity consumption and qualitative estimation of the companies' competitive positions in terms of their energy efficiency.Methods. The research is based on the model for assessing the competitive status of energy efficiency as a derivative of electricity consumption. The composite method of estimating the company's electricity consumption comprises determination of the competition intensity indicator along with the assessment of the energy market capacity.Findings. The indicators of internal potential of enterprises' electricity consumption, the competitive position in certain segments of the electricity consumption market, the company's ability to withstand the influence of external factors are determined. Analysis of the conducted calculations allowed to identify leaders and outsiders among the companies competing for energy efficiency status.Originality. Estimation of the energy efficiency status level of Ukrainian mining companies contains new approaches to using mathematical and statistical analysis methods modified in accordance with the industry specifics. Practical implications.The obtained results can be used to carry out a comprehensive analysis of the electricity consumption management. Considering the company life cycle will allow to assess its financial resources, its ability to achieve a certain level of energy resources efficient use and to determine the external and internal factors that influence the management of the company power supply, and to predict changes in its energy consumption indicators.

“…There are several recent studies that have investigated energy efficiency potential in the iron and steel industry, see for example Morrow Iii et al, 2013;Moya and Pardo, 2013;Pardo and Moya, 2013). Hasanbeigi et al (2013) investigated cost-effective fuel and electricity saving technologies and they concluded that by implementing these in the Chinese iron and steel industry, in total 3.3 PWh fuel and 251 TWh electricity could be saved during the time period -2030.…”

“…This moderate decrease was explained by the maturity of the integrated route in Europe. Pardo and Moya (2013) simulated the evolution of the EU27 iron and steel industry up to 2030. They analysed the implementation of BAT and diffusion of innovative technologies, and how the evolution would be affected by increased energy and resource prices and CO 2 emissions charges.…”

Improved Energy Efficiency and Fuel Substitution in the Iron and Steel Industry

IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. It is vital to reduce anthropogenic emissions of GHGs in order to combat climate change. Industry accounts for 20% of global anthropogenic CO2 emissions and the iron and steel industry accounts for 30% of industrial emissions. The iron and steel industry is at date highly dependent on fossil fuels and electricity. Energy efficiency measures and substitution of fossil fuels with renewable energy would make an important contribution to the efforts to reduce emissions of GHGs. This thesis studies energy efficiency measures and fuel substitution in the iron and steel industry and focuses on recovery and utilisation of excess energy and substitution of fossil fuels with biomass. Energy systems analysis has been used to investigate how changes in the iron and steel industry’s energy system would affect the steel plant’s economy and global CO2 emissions. The thesis also studies energy management practices in the Swedish iron and steel industry with the focus on how energy managers think about why energy efficiency measures are implemented or why they are not implemented. In-depth interviews with energy managers at eleven Swedish steel plants were conducted to analyse energy management practices. In order to show some of the large untapped heat flows in industry, excess heat recovery potential in the industrial sector in Gävleborg County in Sweden was analysed. Under the assumptions made in this thesis, the recovery output would be more than three times higher if the excess heat is used in a district heating system than if electricity is generated. An economic evaluation was performed for three electricity generation technologies for the conversion of low-temperature industrial excess heat. The results show that electricity generation with organic Rankine cycles and phase change material engines could be profitable, but that thermoelectric generation of electricity from low-temperature industrial excess heat would not be profitable at the present stage of technology development. With regard to fossil fuels substituted with biomass, there are opportunities to substitute fossil coal with charcoal in the blast furnace and to substitute liquefied petroleum gas (LPG) with bio-syngas or bio synthetic natural gas (bio-SNG) as fuel in the steel industry’s reheating furnaces. However, in the energy market scenarios studied, substituting LPG with bio-SNG as fuel in reheating furnaces at the studied scrap-based steel plant would not be profitable without economic policy support. The development of the energy market is shown to play a vital role for the outcome of how different measures would affect global CO2 emissions. Results from the interviews show that Swedish steel companies regard improved...
