The two most common types of biofuel are bioethanol and biodiesel. Brazil is the largest producer of bioethanol, while the EU is the largest producer of biodiesel. The energy content in the global production of bioethanol and biodiesel is 2.2 and 1.8 EJ per year, respectively. [17]
US ethanol production reached 57.54 × 10 9 liters (15.20 × 10 ^ 9 U.S. gal; 12.66 × 10 ^ 9 imp gal) in May 2017. [ 3 ] 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.
Enzymes required for maize grain ethanol production cost 2.64-5.28 US dollars per cubic meter of ethanol produced. Enzymes for cellulosic ethanol production are projected to cost 79.25 US dollars, meaning they are 20-40 times more expensive. [71] The cost differences are attributed to quantity required.
The United States and Brazil lead the industrial world in global ethanol production, with Brazil as the world's largest exporter and biofuel industry leader. [124] In 2006 the U.S. produced 18.4 billion liters (4.86 billion gallons ), closely followed by Brazil with 16.3 billion liters (4.3 billion gallons), [ 17 ] producing together 70% of the ...
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 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. [1]
Biofuels include bioethanol, an alcohol made by fermentation—often used as a gasoline additive, and biodiesel, which is usually used as a diesel additive. Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1]
Bioethanol also refers to the technology of using principally corn (maize seed) to make ethanol directly through fermentation. However, under certain field and process conditions this process can consume as much energy as is the energy value of the ethanol it produces, therefore being non-sustainable.
