Download or read book Alcohol Fuel written by Richard Freudenberger and published by New Society Publishers. This book was released on 2009-11-01 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dwindling petroleum supplies and growing environmental concerns are significantly impacting the cost of petro-fuel and its infrastructure. The search for alternative fuel sources has led to ethanol, a gasoline substitute that is already in the marketplace as Gasohol and E-85. But large-scale production of corn-based ethanol is controversial as it threatens the world’s food supply. There are alternatives, however: Brazil uses sugar cane, which is up to six times more productive in energy conversion. After the energy crisis of the 1970s, there was a lot of misinformation about the cost of individual ethanol production. In order to achieve energy independence from gasoline, ethanol lends itself to small-scale production, and especially to cooperative ventures in rural communities, often using “waste” feedstock. Alcohol Fuel is a practical, grassroots book that will give readers all the information they need, covering every aspect of making and using ethanol for fuel, including: *Permitting and planning *Budgeting and setup *Sourcing feedstocks *Finding and building distillation equipment *Storage and safety *Practical applications for converting motor vehicles, farm equipment, and space-heating systems The practical, user-friendly information on basic equipment needs, fermentation recipes, and distillation designs will be of interest to readers looking for information, as well as to those ready to make the switch. Richard Freudenberger was research director of Mother Earth News, where he managed the Alcohol Fuel Program and developed solar and renewable solar and energy projects. He is publisher and technical editor of BackHome magazine and lives in Hendersonville, North Carolina.

Download or read book Biofuels and Sustainability written by Kazuhiko Takeuchi and published by Springer. This book was released on 2018-07-13 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents a comprehensive analysis of biofuel use strategies from an interdisciplinary perspective using sustainability science. This interdisciplinary perspective (social science-natural science) means that the strategies and policy options proposed will have significant impacts on the economy and society alike. Biofuels are expected to contribute to reducing greenhouse gas emissions, revitalizing economies in agricultural communities and alleviating poverty. However, despite these anticipated benefits, international organizations such as the FAO, OECD and UN have published reports expressing concerns that biofuel promotion may lead to deforestation, water pollution and water shortages. The impacts of biofuel use are extensive, cross-sectoral and complex, and as such, comprehensive analyses are required in order to assess the extent to which biofuels can contribute to sustainable societies. Applying interdisciplinary sustainability science concepts and methodologies, the book helps to enhance the establishment of a sustainable society as well as the development of appropriate responses to a global need for urgent action on current issues related to biofuels.

Download or read book Duckweed Ethanol written by Christopher Kinkaid and published by CreateSpace. This book was released on 2014-07-13 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The smallest flowering plant, on Earth, is one of the most powerful, and widespread: duckweed. Usually, considered a nuisance, duckweed, upon close examination, is an impressive crop, in photosynthetic value. Ethanol, an industry dominated by the Corn Industry (King Corn), faces many challenges, including large water draws, rising fertilizer costs, large diesel fuel bills, and unintended impacts on Food markets. Corn, as a choice for ethanol production, pits food, versus fuel, for agricultural resources, increasing stresses between fundamental markets. An ideal source of biomass, for ethanol production, would not be a food crop, rather, a waste-crop. King Corn, dominates current domestic ethanol production markets, worth billions, each year. Supported with Federal Farm Subsidies, worth billions of dollars annually, the corn industry dictates the US ethanol markets, using Corn as the principle feedstock crop. At first glance, Corn, is an odd choice for ethanol production. Corn, began as a wild seed crop, domesticated by ancient man. Before the modern age, thousands of years of selective breeding, produced a Corn rich in proteins, and high in nutritional value. Modern Corn, has been engineered to go "the other direction," and reduce Corn's Protein, and increase Corn's Starch (Carbohydrate) production. The "Starch" in corn, is used for Ethanol production, and other by-products, such as Corn Syrup, and Distillers Dried Grains and Solubles (DDGS). Duckweed, is a choice for bulk biomass, which offers significant advantages over corn. Duckweed advantages include, lower energy costs, lower water resources, lower fertilizer costs, doesn't require valuable farmland, doesn't compete in Food markets, has higher Starch yield, per acre. Duckweed, in a controlled environment, can be grown, year round, and in diverse locations. Corn, as a bulk source of Starch production, competes with Food markets, drinks thousands of gallons of water, per gallon Ethanol produced, requires large diesel fuel bills for growing, and harvesting, requires large amounts of fertilizers, and lower's the nutritional value of Corn on purpose, to produce more starch, reducing protein production, and nutritional value.

Download or read book Lignocellulose Conversion written by Vincenza Faraco and published by Springer Science & Business Media. This book was released on 2013-06-12 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.
Download or read book Renewable Fuel Standard written by National Research Council and published by National Academies Press. This book was released on 2012-01-29 with total page 416 pages. 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.
