Officially, the use of biomass for energy meets only 10-13% of the total global energy demand of 140 000 TWh per year. Still, thirty years ago the official figure was zero, as only traded biomass was included. While the actual production of biomass is in the range of 270 000 TWh per year, most of this is not used for energy purposes, and mostly it is not used very efficiently. Therefore, there is a need for new methods for converting biomass into refined products like chemicals, fuels, wood and paper products, heat, cooling and electric power. Obviously, some biomass is also used as food – our primary life necessity. The different types of conversion methods covered in this volume are biogas production, bio-ethanol production, torrefaction, pyrolysis, high temperature gasifi cation and combustion. This book covers the suitability of different methods for conversion of different types of biomass. Different versions of the conversion methods are presented – both existing methods and those being developed for the future. System optimization using modeling methods and simulation are analyzed to determine advantages and disadvantages of different solutions. Many international experts have contributed to provide an up-to-date view of the situation all over the world. These global perspectives and the inclusion of so much expertise of distinguished international researchers and professionals make this book unique. This book will prove useful and inspiring to professionals, engineers, researchers and students as well as to those working for different authorities and organizations.

Torrefaction of Biomass for Energy Applications: From Fundamentals to Industrial Scale explores the processes, technology, end-use, and economics involved in torrefaction at the industrial scale for heat and power generation. Its authors combine their industry experience with their academic expertise to provide a thorough overview of the topic. Starting at feedstock pretreatment, followed by torrefaction processes, the book includes plant design and operation, safety aspects, and case studies focusing on the needs and challenges of the industrial scale. Commercially available technologies are examined and compared, and their economical evaluation and life cycle assessment are covered as well. Attention is also given to non-woody feedstock, alternative applications, derived fuels, recent advances, and expected future developments. For its practical approach, this book is ideal for professionals in the biomass industry, including those in heat and power generation. It is also a useful reference for researchers and graduate students in the area of biomass and biofuels, and for decision makers, policy makers, and analysts in the energy field. Compares efficiency and performance of different commercially available technologies from the practical aspects of daily operation in an industrial scale plant Presents a cost analysis of the production, logistics, and storage of torrefied biomass Includes case studies addressing challenges that may occur in the daily operation in an industrial scale plant Covers other associated technologies, the densification of torrefied biomass, and non-woody feedstock

Sustainability in agriculture and associated primary industries, which are both energy-intensive, is crucial for the development of any country. Increasing scarcity and resulting high fossil fuel prices combined with the need to significantly reduce greenhouse gas emissions, make the improvement of energy efficient farming and increased use of renewable energy essential. This book provides a technological and scientific endeavor to assist society and farming communities in different regions and scales to improve their productivity and sustainability. To fulfill future needs of a modern sustainable agriculture, this book addresses highly actual topics providing innovative, effective and more sustainable solutions for agriculture by using sustainable, environmentally friendly, renewable energy sources and modern energy efficient, cost-improved technologies. The book highlights new areas of research, and further R&D needs. It helps to improve food security for the rapidly growing world population and to reduce carbon dioxide emissions from fossil fuel use in agriculture, which presently contributes 22% of the global carbon dioxide emissions. This book provides a source of information, stimuli and incentives for what and how new and energy efficient technologies can be applied as effective tools and solutions in agricultural production to satisfy the continually increasing demand for food and fibre in an economically sustainable way, while contributing to global climate change mitigation. It will be useful and inspiring to decision makers working in different authorities, professionals, agricultural engineers, researchers, and students concerned with agriculture and related primay industries, sustainable energy development and climate change mitigation projects.

The discussion about energy perspectives beyond 2020, up to 2030 and eventually 2050 has started. There seems to be a verbal consensus on the necessity of ambitious climate change mitigation policies, without a convincing perspective of the necessary policy decisions to be reached in due time. Methods to achieve greenhouse gas reduction as well as energy security vary from aiming for 100% renewable energies and setting up appropriate policy frameworks to implementing a mix of renewables comprising so-called clean fossil and nuclear energy. This book provides an analysis of the different approaches and the reasons why there is no sustainable alternative to aiming for 100% renewables – and how this vision could come true. The book provides an overview and in-depth analysis of a vital debate. It describes how the present policy framework with 2020-targets for the share of renewables, for increase of energy efficiency and for greenhouse gas emissions reduction was developed and how it has been implemented so far. Furthermore, it describes and analyses the emerging debate about the future of our energy system and the necessary next steps and targets leading up to 2030.

The newest addition to the Green Chemistry and Chemical Engineering series from CRC Press, Biofuels and Bioenergy: Processes and Technologies provides a succinct but in-depth introduction to methods of development and use of biofuels and bioenergy. The book illustrates their great appeal as tools for solving the economic and environmental challenges associated with achieving energy sustainability and independence through the use of clean, renewable alternative energy. Taking a process engineering approach rooted in the fuel and petrochemical fields, this book masterfully integrates coverage of current conventional processes and emerging techniques. Topics covered include: Characterization and analysis of biofuels Process economics Chemistry of process conversion Process engineering and design and associated environmental technologies Energy balances and efficiencies Reactor designs and process configurations Energy materials and process equipment Integration with other conventional fossil fuel processes Byproduct utilization Governmental regulations and policies and global trends After an overview of the subject, the book discusses crop oils, biodiesel, and algae fuels. It examines ethanol from corn and from lignocelluloses and then explores fast pyrolysis and gasification of biomass. Discussing the future of biofuel production, it also describes the conversion of waste to biofuels, bioproducts, and bioenergy and concludes with a discussion of mixed feedstock.
