Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]
The United States became the world's largest producer of ethanol fuel in 2005. The U.S. produced 15.8 billion U.S. liquid gallons of ethanol fuel in 2019, up from 13.9 billion gallons (52.6 billion liters) in 2011, [1] [2] and from 1.62 billion gallons in 2000. [3] Brazil and U.S. production accounted for 87.1% of global production in 2011. [1]
A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
The ethanol and corn industries on Thursday slammed an advisory board to the U.S. Environmental Protection Agency for a draft report that found there could be little climate benefit to using corn ...
Another serious problem with corn ethanol as a replacement for gasoline, is the engine damage on standard vehicles. E10 contains ten percent ethanol and is acceptable for most vehicles on the road today, while E15 contains fifteen percent ethanol and is usually prohibited for cars built before 2001. [ 5 ]
However, modeling uncertainty today is a multiyear development problem," said the letter, which was also signed by ethanol companies including Poet and Archer-Daniels-Midland Co .
Current corn-ethanol technologies are much less petroleum intensive than gasoline however have the GHG emission levels similar to gasoline. [77] The literature is mainly unclear what the GHG emission changes would be by adopting corn-based ethanol for biodiesel. Some studies report a 20% increase in GHG emissions and some report a 32% decrease.
Jul. 10—ONIDA, S.D. — The ethanol plant explosion that rocked Onida on Sunday afternoon is still under investigation by the South Dakota State Fire Marshal. Witnesses in the area said they ...
