Wood Pellet as a Renewable Source of Energy


Book Description

This book takes the reader on a journey from the moment that raw wood material enters the factory to the final pellet consumption. It starts by reviewing biomass application and its role for the future development of renewable energies, discussing different biomass conversion methods as alternatives to direct utilization. The second chapter then comprehensively examines densification processes, with a focus on the pelleting process. Chapter three further elaborates on the pelleting process, including an overview of the pellet structure and properties, and the history of this process. The subsequent chapters provide a detailed account of the production process from raw material delivery to final distribution, addressing the chemical and physical quality, and presenting measurement methods and standards. In the final chapters, the authors describe in detail the pellet combustion process and emissions.

Energy from Organic Materials (Biomass)


Book Description

This comprehensive reference is a state-of-the-art survey of biomass as an energy carrier for the provision of heat, electricity, and transportation fuel, considering technical, economic, environmental, and social aspects. On a global scale, biomass contributes roughly 12 to 16 % of the energy needed to cover the overall primary energy consumption. Thus far, it is humanity’s most important source of renewable energy, used on practically all continents and growing in importance even in industrialized nations. With detailed coverage of the production of solid, gaseous and liquid fuels, as well as a final energy provision, this volume serves as an introduction for readers just entering the field, but also offers new insights, up-to-date information, as well as latest findings for advanced researchers, industry experts, and decision makers.




Biomass Pelletization


Book Description

Environmental and energy dependency problems derived from high fossil fuels consumption have made necessary the development of new energy models to be renewable and sustainable, efficient, practical and economical, and cost effective, to meet the demand for a sustainable energy supply. Among renewable resources, biomass is destined to play an important role in these new energy models since agricultural and forestry residues are an energy resource which is produced in relatively large amounts throughout the world and regarded as a renewable and environmentally safe way of providing energy. Compiling information on the conversion of energy from biomass, the book focuses on the use of pellets as homogeneous solid biofuels. It describes all the changes that forestry and agricultural biomass undergo to be converted into thermal energy and analyses the inputs and outputs of the process. It has to be noted that the standards used as guidelines and references in all the chapters of the book are there in order to not to forget the thresholds and guidelines established and thus to ensure a proper use. This book guides the reader through the entire biomass-to-energy process, emphasising important aspects and how the quality of the biofuel can be identified. It acts as a starting point for professionals and researchers interested in working with biomass and a guide for those people interested in the implementation of the technologies described.




International Bioenergy Trade


Book Description

The trade of global bioenergy commodities, such as ethanol, biodiesel and wood pellets has been growing exponentially in the past decade, and have by 2013 reached true “commodity” volumes, i.e. tens of millions of tonnes traded each year, and billions (both in US$/€) of annual turnover. IEA Bioenergy Task 40 was founded in 2004 and is now in its 4th triennium. For the past 9 years, task 40 has monitored the developments in international bioenergy trade, including the organization of about 20 workshops on trade-related topics, and the publication of over 100 studies, country reports, newsletters, etc. The amount of material produced over the years and insights gained in how biomass markets and international trade of biomass and biofuels has developed is impressive. Besides that the group has produced overviews and insights, also a large amount of practical experience has been brought together in what works and what doesn’t. Last but not least, based on all this, there are clear(er) views on how to proceed to build working sustainable international biomass markets in the future. This book compiles those lessons and insights into an easily accessible book publication.

America's Energy Future


Book Description

For multi-user PDF licensing, please contact customer service. Energy touches our lives in countless ways and its costs are felt when we fill up at the gas pump, pay our home heating bills, and keep businesses both large and small running. There are long-term costs as well: to the environment, as natural resources are depleted and pollution contributes to global climate change, and to national security and independence, as many of the world's current energy sources are increasingly concentrated in geopolitically unstable regions. The country's challenge is to develop an energy portfolio that addresses these concerns while still providing sufficient, affordable energy reserves for the nation. The United States has enormous resources to put behind solutions to this energy challenge; the dilemma is to identify which solutions are the right ones. Before deciding which energy technologies to develop, and on what timeline, we need to understand them better. America's Energy Future analyzes the potential of a wide range of technologies for generation, distribution, and conservation of energy. This book considers technologies to increase energy efficiency, coal-fired power generation, nuclear power, renewable energy, oil and natural gas, and alternative transportation fuels. It offers a detailed assessment of the associated impacts and projected costs of implementing each technology and categorizes them into three time frames for implementation.
