Ethanol is a renewable, domestically produced alcohol fuel made from plant material, such as corn, sugar cane, or grasses. Using ethanol can reduce oil dependence and greenhouse gas (GHG) emissions. Ethanol fuel use in the U.S. has increased dramatically from about 1.7 billion gallons in 2001 to about 14.4 billion in 2016.1.
Ethanol Fermentation. Ethanol, which is a type of alcohol, is one of the most popular biofuels. It can be made out of feedstocks such as corn, barley and sugarcane through a chemical process known as ethanol fermentation. Any sugars such as glucose, fructose and sucrose that be converted into cellular energy can produce ethanol. Yeast performs the conversion in the absence of oxygen, which means ethanol fermentation is anaerobic. Fermentation is one of the oldest chemical processes that humans became familiarized with. It can be used to make fuels, several types of food, flavoring, beverages, pharmaceuticals, and chemicals.
