Book excerpt: Adoption of efficient end-use technologies is one of the key measures for reducing greenhouse gas (GHG) emissions. With the working of energy programs and policies on carbon regulation, how to effectively analyze and manage the costs associated with GHG reductions become extremely important for the industry and policy makers around the world. Energy-climate (EC) models are often used for analyzing the costs of reducing GHG emissions (e.g., carbon emission) for various emission-reduction measures, because an accurate estimation of these costs is critical for identifying and choosing optimal emission reduction measures, and for developing related policy options to accelerate market adoption and technology implementation. However, accuracies of assessing of GHG-emission reduction costs by taking into account the adoption of energy efficiency technologies will depend on how well these end-use technologies are represented in integrated assessment models (IAM) and other energy-climate models. In this report, we first conduct brief overview on different representations of end-use technologies (mitigation measures) in various energy-climate models, followed by problem statements, and a description of the basic concepts of quantifying the cost of conserved energy including integrating non-regrets options. A non-regrets option is defined as a GHG reduction option that is cost effective, without considering their additional benefits related to reducing GHG emissions. Based upon these, we develop information on costs of mitigation measures and technological change. These serve as the basis for collating the data on energy savings and costs for their future use in integrated assessment models. In addition to descriptions of the iron and steel making processes, and the mitigation measures identified in this study, the report includes tabulated databases on costs of measure implementation, energy savings, carbon-emission reduction, and lifetimes. The cost curve data on mitigation measures are available over time, which allows an estimation of technological change over a decade-long historical period. In particular, the report will describe new treatment of technological change in energy-climate modeling for this industry sector, i.e., assessing the changes in costs and energy-savings potentials via comparing 1994 and 2002 conservation supply curves. In this study, we compared the same set of mitigation measures for both 1994 and 2002 -- no additional mitigation measure for year 2002 was included due to unavailability of such data. Therefore, the estimated potentials in total energy savings and carbon reduction would most likely be more conservative for year 2002 in this study. Based upon the cost curves, the rate of change in the savings potential at a given cost can be evaluated and be used to estimate future rates of change that can be the input for energy-climate models. Through characterizing energy-efficiency technology costs and improvement potentials, we have developed and presented energy cost curves for energy efficiency measures applicable to the U.S. iron and steel industry for the years 1994 and 2002. The cost curves can change significantly under various scenarios: the baseline year, discount rate, energy intensity, production, industry structure (e.g., integrated versus secondary steel making and number of plants), efficiency (or mitigation) measures, share of iron and steel production to which the individual measures can be applied, and inclusion of other non-energy benefits. Inclusion of other non-energy benefits from implementing mitigation measures can reduce the costs of conserved energy significantly. In addition, costs of conserved energy (CCE) for individual mitigation measures increase with the increases in discount rates, resulting in a general increase in total cost of mitigation measures for implementation and operation with a higher discount rate. In 1994, integrated steel mills in the U.S. produced 55.

Download or read book A Bottom up Energy Efficiency Improvement Roadmap for China s Iron and Steel Industry Up to 2050 written by and published by . This book was released on 2016 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron and steel manufacturing is energy intensive in China and in the world. China is the world largest steel producer accounting for around half of the world steel production. In this study, we use a bottom-up energy consumption model to analyze four steel-production and energy-efficiency scenarios and evaluate the potential for energy savings from energy-efficient technologies in China's iron and steel industry between 2010 and 2050. The results show that China's steel production will rise and peak in the year 2020 at 860 million tons (Mt) per year for the base-case scenario and 680 Mt for the advanced energy-efficiency scenario. From 2020 on, production will gradually decrease to about 510 Mt and 400 Mt in 2050, for the base-case and advanced scenarios, respectively. Energy intensity will decrease from 21.2 gigajoules per ton (G/t) in 2010 to 12.2 GJ/t and 9.9 GJ/t in 2050 for the base-case and advanced scenarios, respectively. In the near term, decreases in iron and steel industry energy intensity will come from adoption of energy-efficient technologies. In the long term, a shift in the production structure of China's iron and steel industry, reducing the share of blast furnace/basic oxygen furnace production and increasing the share of electric-arc furnace production while reducing the use of pig iron as a feedstock to electric-arc furnaces will continue to reduce the sector's energy consumption. We discuss barriers to achieving these energy-efficiency gains and make policy recommendations to support improved energy efficiency and a shift in the nature of iron and steel production in China.

This book was released on 2013-06-29 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book does not give a prediction of what the efficiency will be of the energy use of industrial processes in the future. However, it does give an exploration of limits to the efficiency of current processes and an indication of what might be achieved if new technologies can be developed. At the Department of Science, Technology and Society of Utrecht University research had been done to the opportunities for improvement of the energy efficiency in the short term since the 1980's. This had resulted in a comprehensive database on energy efficient measures. This database and a possible application are described in Chapter 3 of this book. The use of the database induced new research themes around efficiency improvement, e.g. concerning barriers for implementation of measures. It was around 1993 that I did a preliminary study to the potential for efficiency improvement in the long term. Historical analysis had shown us that the short term potential stayed constant over the years. It seemed to be replenished by the introduction of new technologies. This lead to the question whether there are limits to the efficiency, taking into account both thermodynamic considerations and ideas on the development and dissemination of new technologies.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation supply curves are a common tool in economic analysis. As such, they provide an important opportunity to include a non-linear representation of technology and technological change in economy-wide models. Because supply curves are closely related to production isoquants, we explore the possibility of using bottom-up technology assessments to inform top-down representations of energy models of the U.S. economy. Based on a recent report by LBNL and ACEEE on emerging industrial technologies within the United States, we have constructed a supply curve for 54 such technologies for the year 2015. Each of the selected technologies has been assessed with respect to energy efficiency characteristics, likely energy savings by 2015, economics, and environmental performance, as well as needs for further development or implementation of the technology. The technical potential for primary energy savings of the 54 identified technologies is equal to 3.54 Quads, or 8.4 percent of the assume d2015 industrial energy consumption. Based on the supply curve, assuming a discount rate of 15 percent and 2015 prices as forecasted in the Annual Energy Outlook2002, we estimate the economic potential to be 2.66 Quads - or 6.3 percent of the assumed forecast consumption for 2015. In addition, we further estimate how much these industrial technologies might contribute to standard reference case projections, and how much additional energy savings might be available assuming a different mix of policies and incentives. Finally, we review the prospects for integrating the findings of this and similar studies into standard economic models. Although further work needs to be completed to provide the necessary link between supply curves and production isoquants, it is hoped that this link will be a useful starting point for discussion with developers of energy-economic models.

This book was released on 2012-12-06 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is universally recognized that the end of the current and the beginning of the next century will be characterized by a radical change in the existing trends in the economic development of all countries and a transition to new principles of economic management on the basis of a resource and energy conservation policy. Thus there is an urgent necessity to study methods, technical aids and economic consequences of this change, and particularly, to determine the possible amounts of energy resources which could be conserved (energy "reserves") in different spheres of the national economy. An increased interest towards energy conservation in industry, one of the largest energy consumers, is quite natural and is manifested by the large num ber of publications on this topic. But the majority of publications are devoted to the solution of narrowly defined problems, determination of energy reserves in specific processes and plants, efficiency estimation of individual energy conserva tion measures, etc. However, it is necessary to develop a general methodological approach to the solution of such problems and create a scientific and methodical base for realizing an energy conservation policy. Such an effort is made in this book, which is concerned with methods for studying energy use efficiency in technological processes and estimation of the theoretical and actual energy reserves in a given process, technology, or industrial sector on the basis of their complete energy balances.

This book was released on 2012-08-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial energy efficiency is one of the most important means of reducing the threat of increased global warming. Research however states that despite the existence of numerous technical energy efficiency measures, its deployment is hindered by the existence of various barriers to energy efficiency. The complexity of increasing energy efficiency in manufacturing industry calls for an interdisciplinary approach to the issue. Improving energy efficiency in industrial energy systems applies an interdisciplinary perspective in examining energy efficiency in industrial energy systems, and discusses how “cross-pollinating” perspectives and theories from the social and engineering sciences can enhance our understanding of barriers, energy audits, energy management, policies, and programmes as they pertain to improved energy efficiency in industry. Apart from classical technical approaches from engineering sciences, Improving energy efficiency in industrial energy systems couples a sociotechnical perspective to increased energy efficiency in industry, showing that industrial energy efficiency can be expected to be shaped by social and commercial processes and built on knowledge, routines, institutions, and methods established in networks. The book can be read by researchers and policy-makers, as well as scholars and practicians in the field. “This book is extremely valuable for anyone who is designing or executing energy efficiency policies, schemes or projects aiming at SMEs. Both authors deserve the highest respect, and the combination of their expertise makes the results truly unique.” - Daniel Lundqvist, programme manager at the Swedish energy agency “For anyone interested in improving energy efficiency in industry, this is a must-read. The book combines tools from social science and engineering to discuss the state of art today as well as possible development path tomorrow. This is a compelling book that I find useful both in my teaching and my research.” - Kajsa Ellegård, Professor at Linköping University, Sweden "The book Improving energy efficiency in industrial energy systems is a novel approach on how improved levels of energy efficiency can be reached in industrial energy systems by merging engineering with social sciences. It is with delight that I can recommend their book to anyone interested in the field.”- Mats Söderström, Director Energy Systems Programme, Linköping University, Sweden

Book excerpt: India's 2010 annual crude steel production was 68 Mt which accounted for nearly five percent of the world's annual steel production in the same year. In 2007, roughly 1600 PJ were consumed by India's iron and steel industry to produce 53 Mt of steel. We identified and analyzed 25 energy efficiency technologies and measures applicable to the processes in the Indian iron and steel industry. The Conservation Supply Curve (CSC) used in this study is an analytical tool that captures both the engineering and the economic perspectives of energy conservation. Using a bottom-up electricity CSC model and compared to an electricity price forecast the cumulative plant-level cost-effective electricity savings potential for the Indian iron and steel industry for 2010-2030 is estimated to be 66 TWh, and the cumulative plant-level technical electricity saving potential is only slightly greater than 66 TWh for the same period. The primary energy related CO2 emissions reduction associated with cost-effective electricity savings is 65 Mt CO2. Compared to a fuel price forecast, an estimated cumulative cost-effective fuel savings potential of 768 PJ with associated CO2 emission reduction of 67 Mt CO2 during 2010-2030 is possible. In addition, a sensitivity analysis with respect to the discount rate used is conducted to assess the effect of changes in this parameter on the results.

Book excerpt: Discusses purpose of this study is to derive a new model capable of advanced diagnosis and analysis of energy usage to determine the possible energy efficiency potential through the following in a single model: Analysis of industrial historical data; Prediction of the industrial energy baseline; Computation of the industrial energy efficiency; and Optimization of the industrial energy consumption usage. In this context, the development of a new model involves: Carrying out literature survey; Carrying out Mathematical Analysis of the dynamics of energy efficiency in an industry; Critically analyzing and testing existing models; Evolve a new and novel model; Test the model using data from specific industry; Apply the model to eleven industrial sectors in South Africa. This thesis on energy efficiency potential will be a milestone for different stakeholders, policymakers and decision makers in the energy sector at national and international levels who are, or will be interested in reducing energy input and still produce the observed output levels, by becoming technically efficient. The approach adopted by the study is the integration of Index Decomposition Analysis (IDA), Artificial Neural Network (ANN) and Data Envelopment Analysis (DEA) into a single model.This methodology combines modeling, which is at the core of an energy-management technique, with a wider interpretation of activity growth, structure and efficiency changes which contribute to changes in energy consumption.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial decarbonization is a critical challenge along the pathway to reducing greenhouse gas (GHG) emissions at a sufficient scale and pace to avoid the worst impacts of climate change. The intrinsic energy- and emissions-intensive nature of heavy industry has led to the recognition that efforts to change the profile of industrial energy use could play a major role in meeting this challenge. This concept, defined broadly as industrial energy efficiency, encompasses a category of technology solutions such as process improvements, equipment upgrades, and fuel switching within sector boundaries. These and other efficiency technologies are notable for their potential to lower industrial emissions while improving (rather than reducing) competitiveness. Robust analysis of the costs and benefits of efficiency as a comprehensive technology suite can help to overcome known barriers to adoption including poor awareness of efficiency opportunities and perceptions of high risk for efficiency investments. Understanding the impacts of efficiency can also be beneficial to policymakers by identifying effective emissions reduction pathways. The overall objective of this thesis is to develop a novel method for fully characterizing the techno-economic potential of industrial energy efficiency and in-sector fuel switching as solutions for energy savings and emissions reductions. This thesis demonstrates application of the method to the case study of the Canadian pulp and paper sector. To achieve the objective of this thesis, a technology-explicit energy and GHG emissions modelling and analysis framework was developed based on best practices for studies of energy efficiency and resource potential. The framework integrates a bottom-up sector energy model with a comprehensive database of energy efficiency technologies validated against data from actual projects in industry. Analysis of efficiency measures was linked to the sector energy model at the point of end-use secondary energy consumption, enabling more realistic representation of how efficiency technologies can impact final energy use. Technology-explicit applicability factors and iterative, cumulative analysis techniques were used to capture the expected impacts of measure overlap, interference, and diminishing returns so as to not overestimate the effects of all measures acting in parallel. Energy savings bandwidths and cost of saved energy curves were developed to characterize the energy savings potential associated with efficiency. Energy-driven GHG emissions abatement scenarios were then developed and analyzed within a Canada-wide energy and emissions model over a long-term planning horizon at both the sector and system level. Marginal GHG abatement cost curves were produced to provide insights into the most impactful and cost-effective technologies over the study period. The key findings of this work demonstrate that natural gas, biomass, and net electricity consumption in the Canadian pulp and paper sector could be reduced by 95%, 1%, and 41%, respectively, via adoption of economically viable efficiency technologies at current energy prices. Achieving this potential would significantly improve sector competitiveness by bringing it into alignment with international energy intensity benchmarks and by dramatically reducing energy costs. At current production levels, efficiency in the pulp and paper sector could reduce net demand for natural gas and electricity by 71 PJ/year and 44 PJ/year, respectively. Energy efficiency was also found to have significant potential as a tool for reducing GHG emissions. The annual GHG emissions abatement associated with economical efficiency measures was estimated to be 3.6 MtCO2e (46%) by 2030 and 4.9 MtCO2e (66%) by 2050 relative to business as usual. Accounting for the technical potential of all measures increases the abatement potential to 6.2 MtCO2e in 2050. Over the study period, energy efficiency was found to reduce cumulative sector GHG emissions by 107.6 MtCO2e (42%) through 2050 at a weighted average abatement cost of -$162/tCO2e. When considering system-level effects, the cumulative abatement rises by 44% to 155.6 MtCO2e through 2050. The results presented in this thesis provide a clear indication to industry and policymakers that energy efficiency could be the single most important technology solution to achieve emissions reduction targets at low or negative cost while enhancing pulp and paper sector competitiveness. The novel framework developed in this thesis can be adapted to any other jurisdiction or sector to produce similar insights. Further work is needed to determine how best to achieve the potential associated with industrial energy efficiency so that it can take a leading role in the transition to a prosperous low-carbon economy.
