Ethanol-blended fuel is widely used in Brazil, the United States, Canada, and Europe (see also Ethanol fuel by country). [2] Most cars on the road today in the U.S. can run on blends of up to 15% ethanol, [6] and ethanol represented 10% of the U.S. gasoline fuel supply derived from domestic sources in 2011. [2]
Ford, Chrysler, and GM are among many automobile companies that sell flexible-fuel vehicles that can run blends ranging from pure gasoline to 85% ethanol , and beginning in 2008 almost any type of automobile and light duty vehicle was available with the flex-fuel option, including sedans, vans, SUVs and pickup trucks.
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
Corn ethanol is ethanol produced from corn biomass and is the main source of ethanol fuel in the United States, mandated to be blended with gasoline in the Renewable Fuel Standard. Corn ethanol is produced by ethanol fermentation and distillation. It is debatable whether the production and use of corn ethanol results in lower greenhouse gas ...
Ethanol's chemical composition. Similar to other gasoline structures, biodiesel is built from a foundation of hydrocarbons. BG100, or 100% biogasoline, is formulated so that it can immediately be used as a drop-in substitute for petroleum-derived gasoline in any conventional gasoline engine, unlike ethanol.
The amount of ethanol used in the United States is also limited by the number of Flex Fuel vehicles available which are capable of operating on ethanol blends as high as 85% (E85) and the relative pricing of E85 as compared to regular gasoline (E10). Other alternative fuels may have higher functional "blend walls".
The EPA announced that the 2009 Renewable Fuel Standard will require most refiners, importers, and non-oxygenate blenders of gasoline to displace 10.21% of their gasoline with renewable fuels such as ethanol.
An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum-based fossil fuels such as gasoline, petrodiesel or liquefied petroleum gas . The term typically refers to internal combustion engine vehicles or fuel cell vehicles that utilize synthetic renewable fuels such as biofuels ( ethanol fuel ...
