What's the deal with ethanol?

CalCars and PHEVs Frequently Asked Questions
The enthusiasm for ethanol ("flex-fuel" cars use E85, which is 85% ethanol and 15% gasoline) is welcome. But it works best if we use plug-in hybrids to power most of our miles electrically. Otherwise we'll need more ethanol than we can make sustainably. A combination solution: increasingly renewable electricity as the primary fuel and ethanol as the range extender.

Money: Ethanol explained - US News and World Report
Ethanol is a fuel that comes from agricultural crops such as corn, barley, and wheat—and even from trees and grasses. Unlike fossil fuels, such as petroleum, these are renewable resources. And such crops can be grown in the United States and many other countries. If more cars ran on ethanol, that would, theoretically, reduce American dependence on oil from the Middle East and other unstable regions.

DMB - Frequently Asked Questions About E85
Ethanol is a high octane, domestically produced and renewable fuel that is made from corn or other grains. It burns cleaner than gasoline, thus reducing greenhouse gas emissions. Ethanol is biodegradable and does not contaminate water supplies. Ethanol is used as a gasoline additive to replace MTBE (methyl tertiary butyl ether) as an oxygenate that helps fuel to burn more completely and more cleanly.

Sunnyside Ethanol, LLC
Ethanol is ethyl alcohol, a fuel component made primarily from corn and various other grains. According to the Renewable Fuels Association, approximately 85% of ethanol in the United States today is produced from corn. Sunnyside's production facilities will use corn as the major feedstock in its production of ethanol. Corn produces large quantities of carbohydrates, which convert into glucose more easily than most other kinds of biomass.

TDEC: Alternative Fuels: E85 FAQs
Ethanol is alcohol used in transportation fuels. It is a high octane, liquid, renewable fuel, produced by the fermentation of plant sugars. In the United States, ethanol is typically produced from corn and other grain products, although in the future it may be economically produced from other biomass resources such as agricultural and forestry wastes, specially grown energy crops, or even municipal garbage!

FAQ
Ethanol is "ethyl alcohol," 200-proof grain alcohol. An ethanol plant produces fuel-grade ethanol, and that ethanol is then blended in a percentage with gasoline to make a finished motor fuel. Terminology is important because the term "ethanol" means different things to different people: Sometimes people say "ethanol" and mean the blend of 10% ethanol / 90% gasoline called E10.

Office of Bioenergy Programs
Ethanol is an ethyl alcohol that is produced by the fermentation and distillation of sugars obtained from grains or plants. Ethanol is typically produced in two ways, from corn grains or from plant materials called biomass. The difference between the two is the method in which the sugars are extracted from the materials. The process to extract sugars from biomass is slightly more complex than the corn grain process.

Can I use E85 (ethanol) in my gasoline vehicle?

Frequently Asked Questions (FAQ)
Some automakers have recently been building E85 capability into all instances of certain of their models; for example, all 2003 DaimlerChrysler vehicles (cars and minivans) with their 3.3-liter V6 engine can run on E85. However, in general a vehicle must be tuned to use ethanol; its requirements for fuel-air mixture and spark timing, in particular, are significantly different from those for gasoline.

Is ethanol good for my car?

driving ethanol: Frequently Asked Questions
A:Yes! Gasoline enriched with ethanol performs in much the same way that regular gasoline does, and actually surpasses regular gasoline in key performance categories. All auto manufacturers who sell cars in the United States approve fuels enriched with up to 10 percent ethanol — and many recommend it for its clean-burning benefits.

What is the ethanol "subsidy"?

e85 Inc.
Many are misinformed, believing that ethanol producers receive a huge government subsidy. That is a myth. In fact, ethanol's "subsidy" is really a federal tax credit that goes to oil companies as an incentive to blend ethanol with gasoline. This blender's tax credit totals 51 cents per gallon of ethanol or 5.1 cents per gallon on E10.

What is cellulosic ethanol?

e85 Inc.
Cellulosic biomass, dubbed the most abundant material on earth, holds tremendous promise as a feedstock for ethanol production due to its widespread availability and potential for high fuel yields. Examples of sources for cellulosic ethanol include corn stover (the stalks and husks left over after harvest), wheat and barley straw, sugarcane or rice bagasse, sawdust, paper pulp, small diameter trees, and dedicated energy crops such as switchgrass and other fast-growing grasses.

Back to Top How is ethanol produced?

Frequently Asked Questions
Ethanol is produced from starch. All agricultural crops and residues contain starch, which is a polymer of glucose, a six-carbon sugar. To produce ethanol from grain, the starch portion of the grain is exposed and mixed with water to form a mash. The mash is heated and enzymes are added to convert the starch into glucose. The next phase, fermentation, involves the addition of yeast to convert the glucose to ethanol and carbon dioxide.

How is ethanol produced?

DMB - Frequently Asked Questions About E85
Ethanol is produced by fermenting the starch in corn or other grain crops. The fermented starch is distilled into alcohol and excess water is removed, resulting in very pure ethyl alcohol that can be mixed with gasoline. One bushel of corn yields 2.8 gallons of ethanol. The starch portion of corn is about 70%. The remaining 30% left over after starch is extracted is used as highly nutritious animal feed. In 2005, about 14% (1.
