Ethanol fuel is fuel containing ethyl alcohol, the same type of alcohol as found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline.
Panicum virgatum, commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55°N latitude in Canada southwards into the United States and Mexico. Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. It is used primarily for soil conservation, forage production, game cover, as an ornamental grass, in phytoremediation projects, fiber, electricity, heat production, for biosequestration of atmospheric carbon dioxide, and more recently as a biomass crop for ethanol and butanol.
Cellulosic ethanol is ethanol produced from cellulose rather than from the plant's seeds or fruit. It can be produced from grasses, wood, algae, or other plants. It is generally discussed for use as a biofuel. The carbon dioxide that plants absorb as they grow offsets some of the carbon dioxide emitted when ethanol made from them is burned, so cellulosic ethanol fuel has the potential to have a lower carbon footprint than fossil fuels.
Corn stover consists of the leaves, stalks, and cobs of corn (maize) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very common agricultural product in areas of large amounts of corn production. As well as the non-grain part of harvested corn, the stover can also contain other weeds and grasses. Field corn and sweet corn, two different types of maize, have relatively similar corn stover.
Iogen Corporation is a Canadian company based in Ottawa, Ontario, Canada, and was founded by Patrick Foody Sr. in 1975.
Xethanol AMEX: XNL was one of the smaller producers of corn ethanol in the United States, and one of the few publicly traded companies developing technology for producing cellulose ethanol. Ethanol fuel will have increased production from a current level of about 5 billion US gallons (19,000,000 m3) per year to over 20 billion US gallons (76,000,000 m3) annually. Potentially 60 to 100 billion US gallons of ethanol could be produced annually in a sustainable manner from domestic biomass resources. To achieve these goals some believe it will be necessary to develop and commercialize technology for the production of ethanol from cellulose and hemicellulose. Xethanol says it plans to increase production and profitability with new technology it has under development.
The United States produces mainly biodiesel and ethanol fuel, which uses corn as the main feedstock. The US is the world's largest producer of ethanol, having produced nearly 16 billion gallons in 2017 alone. The United States, together with Brazil accounted for 85 percent of all ethanol production, with total world production of 27.05 billion gallons. Biodiesel is commercially available in most oilseed-producing states. As of 2005, it was somewhat more expensive than fossil diesel, though it is still commonly produced in relatively small quantities, in comparison to petroleum products and ethanol fuel.
The Energy Independence and Security Act of 2007, originally named the Clean Energy Act of 2007, is an Act of Congress concerning the energy policy of the United States. As part of the Democratic Party's 100-Hour Plan during the 110th Congress, it was introduced in the United States House of Representatives by Representative Nick Rahall of West Virginia, along with 198 cosponsors. Even though Rahall was 1 of only 4 Democrats to oppose the final bill, it passed in the House without amendment in January 2007. When the Act was introduced in the Senate in June 2007, it was combined with Senate Bill S. 1419: Renewable Fuels, Consumer Protection, and Energy Efficiency Act of 2007. This amended version passed the Senate on June 21, 2007. After further amendments and negotiation between the House and Senate, a revised bill passed both houses on December 18, 2007 and President Bush, a Republican, signed it into law on December 19, 2007, in response to his "Twenty in Ten" challenge to reduce gasoline consumption by 20% in 10 years.
VeraSun Energy Corporation was a leading producer of renewable fuel. Founded in 2001, the company at one time had a fleet of 16 production facilities in eight states, of which one was still under construction. VeraSun Energy was scheduled to have an annual production capacity of approximately 1.64 billion US gallons (6,200,000 m3) of ethanol and more than 5 million tons of distillers grains by the end of 2008. The company also had begun construction at its Aurora, South Dakota facility to extract oil from dried distillers grains, a co-product of the ethanol process, for use in biodiesel production.
The Food, Conservation, and Energy Act of 2008 was a $288 billion, five-year agricultural policy bill that was passed into law by the United States Congress on June 18, 2008. The bill was a continuation of the 2002 Farm Bill. It continues the United States' long history of agricultural subsidies as well as pursuing areas such as energy, conservation, nutrition, and rural development. Some specific initiatives in the bill include increases in Food Stamp benefits, increased support for the production of cellulosic ethanol, and money for the research of pests, diseases and other agricultural problems.
Biogasoline is a type of gasoline produced from biomass such as algae. Like traditionally produced gasoline, it is made up of hydrocarbons with 6 (hexane) to 12 (dodecane) carbon atoms per molecule and can be used in internal combustion engines. However, unlike traditional gasoline/petroleum based fuels, which are mainly composed from oil, biogasolines are made from plants such as beets and sugarcane or cellulosic biomass- substances normally referred to as plant waste.
Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuels production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views and is a long-standing, controversial one in the literature. There is disagreement about the significance of the issue, what is causing it, and what can or should be done to remedy the situation. This complexity and uncertainty are due to the large number of impacts and feedback loops that can positively or negatively affect the price system. Moreover, the relative strengths of these positive and negative impacts vary in the short and long terms, and involve delayed effects. The academic side of the debate is also blurred by the use of different economic models and competing forms of statistical analysis.
Coskata, Inc. was a Warrenville, Illinois–based energy company incorporated in 2006 by serial entrepreneur Andrew Perlman's GreatPoint Ventures group. The company was developing processes for the production of cellulosic ethanol from woodchips. Coskata's process combines both biological and thermochemical processing. The estimated cost of production via this technology was reported as under $1 per gallon, as opposed to corn-based ethanol costing approximately $1.40 per gallon
The use of biofuels varies by region. The world leaders in biofuel development and use are Brazil, United States, France, Sweden and Germany.
Mascoma Corporation was a U.S. biofuel company founded to produce cellulosic ethanol made from wood and switchgrass. Headquartered in Lebanon, New Hampshire, the company was founded in 2005 by Robert Johnsen (CEO), Lee Lynd and Charles Wyman, two professors from Dartmouth College. The company was named after Mascoma Lake, which is near Lebanon. In November 2014, the yeast-related business assets including the Mascoma name were purchased by Lallemand, Inc. of Montreal, Canada. The R&D facility in Lebanon, NH was renamed Mascoma LLC which is now a subsidiary of Lallemand. The remaining business assets of the former Mascoma Corp. including the thermophilic bacteria technology, pilot plant in Rome, NY, and former headquarters in Waltham, MA were renamed Enchi Corporation.
Ethanol is not presently manufactured in Hawaii. Between April 2, 2006, and June 26, 2015, Hawaii State law required all gasoline sold for vehicles to contain 10% ethanol (E-10). In 2015, the requirement was repealed. In 2010, E-85 became available on a military base for flex fuel use. About 45,000,000 US gallons of ethanol were imported from the Caribbean or continental US in 2009.
United States policy in regard to biofuels, such as ethanol fuel and biodiesel, began in the early 1990s as the government began looking more intensely at biofuels as a way to reduce dependence on foreign oil and increase the nation's overall sustainability. Since then, biofuel policies have been refined, focused on getting the most efficient fuels commercially available, creating fuels that can compete with petroleum-based fuels, and ensuring that the agricultural industry can support and sustain the use of biofuels.
Jeff Broin is the founder of POET, LLC, a leading producer of biofuels and coproducts. He currently serves as chairman and CEO.
Renewable energy in South Dakota involves production of biofuels and generation of electricity from renewable sources of energy such as wind and hydropower. South Dakota is among the states with the highest percentage of electricity generation from renewable resources, typically over 70 percent. In 2011, South Dakota became the first U.S. state to have at least 20% of its electricity generation come from wind power, and by 2022, 84% of its generation was renewable.
