Get The Demand For Ethanol As A Gasoline Substitute - Msu

One of the primary disadvantages of ethanol is that it is not as energy-dense as gasoline. This means that it has a lower energy content and is less efficient than gasoline. As a result, vehicles that use ethanol as a fuel source may not get as many miles per gallon as those that use gasoline.

After seeing strong growth for several years, U.S. ethanol-based demand for corn has plateaued over the last decade at about 5 billion bushels, or roughly 40 percent of U.S. corn production. Recently, demand for transportation fuels was reduced by the Coronavirus (COVID-19) pandemic.

Using ethanol and other alternative fuels and advanced technologies to reduce petroleum consumption continues to strengthen national security and reduce transportation energy costs for businesses and consumers.

The total disturbance value of ethanol to gasoline is 0.8493, while the disturbance value of methanol is 0.2605. The former is 3.26 times higher than the latter. Therefore, the results show that ethanol is more favorable for gasoline combustion.

The big problem is energy density – a gallon of ethanol has only two-thirds the energy density of pure gasoline.

Ethanol has a higher octane number than gasoline, providing premium blending properties. Minimum octane number requirements for gasoline prevent engine knocking and ensure drivability. Lower-octane gasoline is blended with 10% ethanol to attain the standard 87 octane.

Ethanol is a renewable alcohol-based fuel made by fermenting and distilling low-cost, low-maintenance starch crops, such as corn, sugar cane and wheat grown for energy production. Ethanol is the most widely available source of gasoline substitute, and reduces greenhouse gas emissions.

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. Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country).
