Available in PDF, EPUB and Kindle. Book excerpt: Life-Cycle Assessment of Biorefineries, the sixth and last book in the series on biomass-biorefineries discusses the unprecedented growth and development in the emerging concept of a global bio-based economy in which biomass-based biorefineries have attained center stage for the production of fuels and chemicals. It is envisaged that by 2020 a majority of chemicals currently being produced through a chemical route will be produced via a bio-based route. Agro-industrial residues, municipal solid wastes, and forestry wastes have been considered as the most significant feedstocks for such bio-refineries. However, for the techno-economic success of such biorefineries, it is of prime and utmost importance to understand their lifecycle assessment for various aspects. Provides state-of-art information on the basics and fundamental principles of LCA for biorefineries Contains key features for the education and understanding of integrated biorefineries Presents models that are used to cope with land-use changes and their effects on biorefineries Includes relevant case studies that illustrate main points

Available in PDF, EPUB and Kindle. Book excerpt: The United States and China are the world's top two energy consumers and, as of 2010, the two largest economies. Consequently, they have a decisive role to play in the world's clean energy future. Both countries are also motivated by related goals, namely diversified energy portfolios, job creation, energy security, and pollution reduction, making renewable energy development an important strategy with wide-ranging implications. Given the size of their energy markets, any substantial progress the two countries make in advancing use of renewable energy will provide global benefits, in terms of enhanced technological understanding, reduced costs through expanded deployment, and reduced greenhouse gas (GHG) emissions relative to conventional generation from fossil fuels. Within this context, the U.S. National Academies, in collaboration with the Chinese Academy of Sciences (CAS) and Chinese Academy of Engineering (CAE), reviewed renewable energy development and deployment in the two countries, to highlight prospects for collaboration across the research to deployment chain and to suggest strategies which would promote more rapid and economical attainment of renewable energy goals. Main findings and concerning renewable resource assessments, technology development, environmental impacts, market infrastructure, among others, are presented. Specific recommendations have been limited to those judged to be most likely to accelerate the pace of deployment, increase cost-competitiveness, or shape the future market for renewable energy. The recommendations presented here are also pragmatic and achievable.

This book was released on 2016-02-17 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2010 in the subject Environmental Sciences, University of Teesside, language: English, abstract: Biofuels; this renewable source of energy is gaining popularity all over the world to fulfil the global energy requirements. In Europe, including the UK, biofuel is used as liquid transport fuel. However, it is not used as widely as what people estimate. Therefore, the world is facing the problems of harnessing of renewable energy resources, and there are greater concerns about the emissions produced by burning of fossil fuels, such as petroleum and coal, it’s use is unquantifiable and hampering the world’s living ecosystem. Accomplishing the ever increasing demand of energy and to mitigate the problems of climate change by reducing GHG emissions from transport fuel and to promote fuel security and reduces the imports of fuels from energy rich countries, European Union has formulated Biofuel Directive (2003/30/EC) stating that the member states will implement this policy to include at least 5.75% of biofuel in the fossil fuel and increased the recent scenarios of 7% to 20% by 2020. Supporting the directive, the UK government has formulated RTFO policy to implement to reduce the use of fossil fuel by 5% in 2010 and follow the process to obtain the renewable target. Basically, this study focuses on the Life Cycle Analysis (LCA) of biofuel crops as a source of biofuel, such as biodiesel and bioethanol to be used in transportation sectors to meet the renewable target by reducing the GHG emissions and imports of fossil fuel. The subject of the study also gives an overview of the comparative study of the impacts of growing biofuel crops in Nepal and in the UK on environmental and socio-economic issues, like impacts on land, water, biodiversity, and food and energy security. At the outcome of the study, will it be helpful to coin similar model to RTFO in Nepal and gives hint how the model is unfair to implement in Nepal.

Available in PDF, EPUB and Kindle. Book excerpt: Current world fossil oil production is struggling to meet demand and may even show a decline after 2010. It is therefore necessary to develop new energy-efficient production pathways for transportation biofuels. This book offers an insight into three promising and innovative pathways for the biological production of ethanol, biogas and biodiesel. These unconventional methods should provide higher product yields, less stringent feedstock specifications, lower chemical additive demand, reduced waste production and much better energy balances when compared to more traditional methods. One pathway concerns the enzymatic production of a new kind of biodiesel where no glycerol waste is produced and an up to twenty percent higher product yield is obtained. The other two pathways are based on the biological conversion of syngas into ethanol or methane using various kinds of lignocellulosic biomass as the starting point. For each of the three pathways a comparison will be made with competing production methods. The contents reflect extended desktop research and show practical experimental results. Government scientists, academics and biofuel producers with an interest in novel transportation fuels will all find this book to be essential reading.

Available in PDF, EPUB and Kindle. Book excerpt: The potential that biomass energy has to supplement traditional fuels and reduce greenhouse gas emissions has put it front and center in the plan to replace fossil-based fuels with renewable fuels. While much has been written about biomass conversions, no single textbook contains all the information needed to teach a biomass conversion course—until now. Introduction to Biomass Energy Conversions presents a comprehensive review of biomass resources available for conversion into heat, power, and biofuels. The textbook covers biomass characterization and discusses facilities, equipment, and standards (e.g. ASTM or NREL) used for analysis. It examines the range of biomass resources available for conversion and presents traditional biomass conversion processes along with extensive biomass characterization data tables, illustrations, and graphical presentations of the various biomass energy conversion processes. The author also describes how to set up a laboratory for biomass energy conversion, and presents economics and sustainability issues. Loaded with real-world examples, the text includes numerous worked examples and problems in each chapter. No one knows what the price of oil will be next year or in future decades. It is governed by many factors other than supply and demand (politics, wars, etc.), however, whatever the future of energy is, bio-fuels will play an important role. This technical guide prepares students for managing bio-refineries, no matter what type of bio-fuel is produced. It also provides practicing engineers with a resource for starting a small bio-fuel business.

This book was released on 2013-09-02 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Governments are setting challenging targets to increase the production of energy and transport fuel from sustainable sources. The emphasis is increasingly on renewable sources including wind, solar, geothermal, biomass based biofuel, photovoltaics or energy recovery from waste. What are the environmental consequences of adopting these other sources? How do these various sources compare to each other? Life Cycle Assessment of Renewable Energy Sources tries to answer these questions based on the universally adopted method of Life Cycle Assessment (LCA). This book introduces the concept and importance of LCA in the framework of renewable energy sources and discusses the key issues in conducting their LCA. This is followed by an in-depth discussion of LCA for some of the most common bioenergy sources such as agricultural production systems for biogas and bioethanol, biogas from grass, biodiesel from palm oil, biodiesel from used cooking oil and animal fat, Jatropha biodiesel, lignocellulosic bioethanol, ethanol from cassava and sugarcane molasses, residential photovoltaic systems, wind energy, microalgal biodiesel, biohydrogen and biomethane. Through real examples, the versatility of LCA is well emphasized. Written by experts all over the globe, the book is a cornucopia of information on LCA of bioenergy systems and provides a platform for stimulation of new ideas and thoughts. The book is targeted at practitioners of LCA and will become a useful tool for researchers working on different aspects of bioenergy.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life cycle assessment (LCA) is a method for assessing all environmental impacts associated with provisioning a good or service. A life cycle encompasses the system which directly produces a good, as well as all systems and processes on which that system is dependent. The objective of this work is to develop a flexible, parameterized model representing a superstructure of life cycles for advanced biofuel production. Parameterizing the model allows users to define a variety of biofuel production scenarios and assess key sustainability metrics, without needing to acquire additional data or perform separate life cycle assessments. Within the model, parameters will include feedstock species and phenotype, a range of farming and harvest practices, feedstock pre-processing, and operating conditions within the biomass conversion process. The model will be used to identify major impact drivers within bioenergy life cycles and aid CBI researchers and leadership in targeting areas where additional R&D efforts will have the most beneficial impacts.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change and increased energy demand have led to the search for alternative sources of energy with low or no global warming potential (GWP). Energy crops are a promising alternative to fossil fuels for a renewable energy future. Both poplar trees and switchgrass are attractive options for perennial energy crops for biofuel production. In this study, a life cycle assessment (LCA) methodology was used to evaluate three agricultural systems. These systems are monoculture poplar trees (PM), monoculture switchgrass (SM), and switchgrass intercropping with poplar trees (IC), grown for ethanol production in an irrigated farm in northeastern Oregon. The objective of this study was using LCA "from cradle to gate": (i) to determine the carbon footprint (CF) of poplar and switchgrass production in monoculture and intercropping systems, and (ii) to assess the energy efficiency of these crops in the systems. The results indicate the CF per unit energy produced and net energy productivity were improved in the intercrop system compared to monoculture of either poplar trees or switchgrass. Although the CF for IC was 160% more than PM and 15% more than SM in CO2 eq ha-1, CF was 5% less than PM and 42% less than SM in CO2 eq MJ-1. In fact, when biomass C was accounted in the CF, all systems have a negative CF. The IC system also contributed to increased energy efficiency compared to monoculture systems, as the energy efficiency ratio was 1.8, 2.0, and 2.9 for PM, SM, and IC respectively. Irrigation, equipment, and fertilizers were the most dominant factors in the systems’ environmental impacts. Assessment indicated the potential of increasing the net energy ratio and reducing CF of bioenergy crops by choosing the most energy efficient and water efficient irrigation system, replacing fossil fuels used in field operations with renewable fuels, and using efficient methods for soil fertilization and enrichment. However even without further improvement, all three biofuel crop systems were net energy producers.

This book was released on 2019-04-08 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Available in PDF, EPUB and Kindle. Book excerpt: In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, wind, geothermal, and biofuels. The United States has a long history with biofuels and the nation is on a course charted to achieve a substantial increase in biofuels. Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative impact on the prices of land, and discusses the potential environmental harm and benefits of biofuels production and the barriers to achieving the RFS2 consumption mandate. Policy makers, investors, leaders in the transportation sector, and others with concerns for the environment, economy, and energy security can rely on the recommendations provided in this report.

This book was released on 2021 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life cycle analysis (LCA) allows for evaluation of the environmental costs of production systems from creation to disposal. Many LCA studies are available for various renewable energy production systems, however, there is a need for LCAs that quantify the benefits of energy coproduction systems. Coproduction systems refer to a partnership of energy production systems that reciprocate waste products in a mutually beneficial way, thereby decreasing waste streams and offsetting input streams from both systems. This study evaluates how biomass crop coproduction with an anaerobic digestion (AD) system affects the life cycle greenhouse gas emissions and material waste streams relative to standalone bioenergy systems. A literature meta-analysis was used to collect life cycle inventories, emissions, and cost for: 1) Advanced biofuel production from perennial grass, 2) Biogas production from AD. The reduction in emissions due to coproduction was 0.28 kgCO2eq per kWh electricity produced. Life cycle impacts were most influenced by the following categories: facility construction, harvest and lignin use, transportation and biorefinery, and effluent, fertilizer, and soil. The cost for coproduction of biogas from food waste and bioethanol from perennial grass was reduced by 10.8% and 7.0%, respectively, when compared to the cost for individually managed systemsts.
