The environmentally friendly renewable energy resources have an increasing share in power generation, but some of them such as solar and wind are discontinuous depending on the primary energy availability and others, such as geothermal and biomass, are baseload resources. The biomass used for energy conversion results basically from plant and animal material residues and also solves a waste management problem. This book analyzes the energy generation by burning biogas from anaerobic digestion and lean syngas in spark ignition engines. The chapters of the book contain: 1) biomass conversion technologies and reciprocating engines utilization, 2) analytical and numerical modeling of the biogas components properties, which fuel biogas spark ignition engines, 3) analytical and numerical modeling of the biogas combustion in spark ignition engines, 4) modeling of heat recovery from the flue gases of spark ignition engines, and 5) analysis of wood biomass and waste gasification lean syngases combustion in spark ignition engines. These analyses are useful to professionals in the energy field.
In a biogas installation, green power is produced from manure and biomass. Because of the optimization and innovation of the biogas industry and the continuously rising energy prices, it is become very interesting to invest in biogas installations. The generated electricity can be sold to energy companies at attractive tariffs for sustainable electricity. The quantity of electricity generated can be guaranteed, making biogas installations attractive investments. For such biogas installation, the digester of the biogas is considered as the main component of the process. Biogas digesters are usually made from steel, concrete, plastics etc, which have a problem of either cost, environmental effect or maintenance problems. To have a sustainable production of biogas, the digester material is required to be renewable. Here it is designed from an engineered wood product, plywood, which insures a more sustainable production and relatively lower cost with acceptable maintenance. The mechanical design of the plywood digester including assembly and installation is done. It is possible to directly integrate the new digester with the mature technology of double membrane biogas holder.
In recent years, the importance of biogas energy has risen manifold and has become universal. This is due to the realization that biogas capture and utilization has great potential in controlling global warming. By capturing biogas wherever it is formed, we not only tap a source of clean energy, but we also prevent the escape of methane to the atmosphere. Given that methane has 25 times greater global warming potential than CO2, methane capture through biogas energy in this manner can contribute substantially towards global warming control.
Biogas technology was introduced in Kenya in the mid 1950's. Since then, only a small percentage of farmers in the country have adopted it. In addition, the functioning status and sustainability of the constructed biogas plants has remained unknown. As the potential of the technology to provide energy for cooking and lighting remain unexploited, prices of other energy sources such as kerosene continue to rise and trees continue to be cut down for firewood and charcoal and hence environmental degradation through deforestation. On the other hand, the firewood produces smoky fumes that cause indoor air pollution and while this is happening, animal waste remains unmanaged. This book sheds light on the socioeconomic and technological constraints to adoption and sustainability of biogas technology among dairy cattle farmers in Nakuru districts, Kenya. The book should be useful to all stakeholders in biogas technology who include governmental and nongovernmental organizations, technology extension agents, farmers as well as research and training institutions.
Development is a process of positive changes. However, development among others destroy ecosystem. In such circumstances, sustainable development is a pattern of resources use in such a way that present needs can be met without destroying the ability for the future generations to meet their needs. It comprises of environmental, economic and social sustainability. Does biogas play vital role for theses sustainability? This book, therefore, provides users' perspective on the role of biogas for sustainability. The work suggests existence of an essential role of biogas for sustainable development by determining its role for quality of life, protecting environment, and social & cultural development in one way or another. This work is most likely to be useful for the biogas actor, researchers, academia and policy makers. It will be useful for biogas actor to grow the sustainable sector. It will be useful for development actors for more commercialization of the sector. The work will also be useful for academia and researchers by acquiring new knowledge in the literature. Finally, the work will be useful for policy makers by providing guide map to formulate biogas-friendly policies.
Energy is most important for economic growth and human development. Every day, we come across food, vegetable wastes and other organic wastes that have huge potential to uplift the society in a better way, when these are transformed into useful bioenergy. To produce bioenergy from biomass one of the better options is to utilize these potential wastes to transform it into biogas. Today, the entire world is looking for different alternative fuels. Biogas is one of the good alternative fuels, energy rich and is well suited as domestic fuel, for heating purposes and power generation. The sources available for the production of biogas are fruit, vegetable wastes and agricultural residues. Biogas from such solid wastes primarily constitutes of methane, carbon dioxide and other trace gases. It is a clean fuel with a calorific value between 5000 to 5500 kcal/kg. There are two methods available for the production of biogas from organic wastes (Dry and Wet Processes). The dry processes include combustion and pyrolysis, whereas the wet processes include anaerobic digestion, gasification and fermentation. This book will be especially useful for Chemical, Mechanical & Agricultural Engineers.

The book Analysis of a Commercial Thermophilic Biogas Plant is a product of a research that identified biodegradable waste materials like domestic/municipal effluence as economically viable alternative source of energy. The proposed Commercial biogas plant was mathematically modeled for urban area clean energy requirement. The capacity of the plant was estimated for a given cycle of operation. A nominal 1500m3 power gas plant was studied characteristically and its performance efficiency evaluated. It was observed that the rate of biogas production is a function of the reactor temperature, pH, substrate concentration, rate of degradation of biomass, and the accumulation of matter in the system due to bacteria growth.
