Assesses the short-term outlook for production of next-generation biofuels and the near-term challenges facing the sector. Next-generation U.S. biofuel capacity should reach about 88 mill. gal. in 2010, thanks to one plant becoming commercially operational in 2010, using non-cellulosic animal fat to produce green diesel. U.S. production capacity for cellulosic biofuels is estimated to be 10 mill. gal. for 2010, much less than the 100 mill. gal. originally mandated in 2007. Near-term sector challenges include reducing high capital and production costs, acquiring financial resources for pre-commercial development, developing new biomass supply arrangements, and overcoming the constraints of ethanol¿s current 10-percent blending limit with gasoline.

This title presents a general but substantial review of the most promising processes and the spectrum of biomass pretreatment, enzymes, chemical catalysts, and hybrid approaches of hydrolyzing biomass into fermentable sugars.
Today the world is facing three critical problems: (i) High fuel prices, (ii) Climatic changes (iii) Air pollution. Currently there are several important problems to be resolved worldwide: (1) high need for energy, (2) high depletion of non-renewable energy resources and (3) high local and global environmental pollution. This book “Biofuels - A Promising alternate for next generation fuels” deals with the production of biofuels. The biggest difference between biofuels and petroleum feedstock is oxygen content. Biofuels have oxygen levels from 10% to 45% while petroleum has essentially none making the chemical properties of biofuels very different from petroleum. Oxygenates are just pre-used hydrocarbons having a structure that provides a reasonable antiknock value. Most traditional biofuels, such as ethanol from corn, wheat, or sugar beets, and biodiesel from oil seeds, are produced from classic agricultural food crops that require high-quality agricultural land for growth. The term biofuel is referred to as liquid or gaseous fuels for the transport sector that are predominantly produced from biomass. There are several reasons for biofuels to be considered as relevant technologies by both developing and industrialized countries. They include energy security reasons, environmental concerns, foreign exchange savings, and socioeconomic issues related to the rural sector. Biomass can be converted to biofuels through various methods like chemical, such as biomethanol and biodiesel production, thermochemical, such as bio-oil, bio-syngas, biohydrogen production, and biochemical, such as bioethanol, biogas, biodiesel and biohydrogen production.

Sustainable Biofuels: Opportunities and challenges, a volume in the "Applied Biotechnology Reviews series, explores the state-of-the-art in research and applied technology for the conversion of all types of biofuels. Its chapters span a broad spectrum of knowledge, from fundamentals and technical aspects to optimization, combinations, economics, and environmental aspects. They cover various facets of research, production, and commercialization of bioethanol, biodiesel, biomethane, biohydrogen, biobutanol, and biojet fuel. This book discusses biochemical, thermochemical, and hydrothermal conversion of unconventional feedstocks, including the role of biotechnology applications to achieve efficiency and competitiveness. Through case studies, techno-economic analysis and sustainability assessment, including life cycle assessment, it goes beyond technical aspects to provides actual resources for better decision-making during the development of commercially viable technology by researchers, PhD students, and practitioners in the field of bioenergy. It is also a useful resource for those in adjacent areas, such as biotechnology, industrial microbiology, chemical engineering, environmental engineering, and sustainability science, who are working on solutions for the bioeconomy. The ability to compare different technologies and their outcome that this book provides is also beneficial for energy analysts, consultants, planners, and policy-makers. The "Applied Biotechnology Reviews series highlights current development and research in biotechnology-related fields, combining in single-volume works the theoretical aspects and real-world applications for better decision-making. - Covers current technologies and advancements in biochemical, thermochemical, and hydrothermal conversion methods for production of various types of biofuels from conventional and nonconventional feedstock - Examines biotechnology processes, including genetic engineering of microorganisms and substrates, applied to biofuel production - Bridges the gap between technology development and prospects of commercialization of bioprocesses, including policy and economics of biofuel production, biofuel value chains, and how to accomplish cost-competitive results and sustainable development
The development of renewable and sustainable lignocellulosic biofuels is currently receiving worldwide attention and investment. Despite decades of research, there remain significant challenges to be overcome before these biofuels can be produced in large volumes at competitive prices. One obstacle is the lack of efficient and affordable catalytic systems to dissolve and hydrolyze polysaccharides into sugars. These sugars are then fed to microrganisms and fermented into biofuels. The price of these catalysts, be they biological, thermochemical, or chemical in nature, represent one of the largest costs in the conversion process. There are a number of catalytic schemes, each with their own advantages and disadvantages, available. This book presents a general yet substantial review of the most promising processes and the spectrum of biomass pretreatment, enzymes, chemical catalysts, and hybrid approaches of hydrolyzing biomass into fermentable sugars. It is the only currently available book that compares the biochemical, chemical, and thermochemical conversion processes to biofuel production.

Biofuel is a renewable energy source produced from natural materials. The benefits of biofuels over traditional petroleum fuels include greater energy security, reduced environmental impact, foreign exchange savings, and socioeconomic issues related to the rural sector. The most common biofuels are produced from classic food crops that require high-quality agricultural land for growth. However, bioethanol can be produced from plentiful, domestic, cellulosic biomass resources such as herbaceous and woody plants, agricultural and forestry residues, and a large portion of municipal and industrial solid waste streams. There is also a growing interest in the use of vegetable oils for making biodiesel. “Biofuels: Securing the Planet’s Future Energy Needs” discusses the production of transportation fuels from biomass (such as wood, straw and even household waste) by Fischer-Tropsch synthesis. The book is an important text for students and researchers in energy engineering, as well as professional fuel engineers.
