How Several Businesses Began Using Ethanol

Ethanol is a clear, colorless liquid that has a mild and pleasant smell. It evaporates easily and burns with a blue flame.

Ethanol, known as Ethyl Alcohol (C2H5OH or C2H6O).

In nature, you can find it wherever yeast is present, like in overripe fruit, and some plants produce it during germination, especially when oxygen levels are low.

Interestingly, it has even been discovered in outer space, forming icy layers around dust particles in large clouds between stars.

Uses

Nowadays, crops such as beet, sugarcane, and maize are the primary sources of ethanol.

Once considered a mystical substance, ethanol’s evolution into a well understood chemical involved various cultures, alchemists, botanists, chemists, and biologists over the centuries.

A key discovery that connected biology to chemistry was Louis Pasteur’s demonstration that living yeast cells ferment sugar into alcohol without oxygen.

History

As a fuel and fuel additive, ethanol has a history spanning 200 years.

In 1826, American inventor Samuel Morey created an engine that operated on ethanol and turpentine.

In 1860, German engineer Nicholas Otto, who is famous for developing the modern internal combustion engine, used ethanol as fuel in one of his engines.

In 1896, Henry Ford built his first car, the quadricycle, to run on pure ethanol. By 1908, he produced the versatile Model T, which could run on ethanol, gasoline, or a mix of both.

Ethanol also played a significant role as fuel for early rockets and is still utilized in some lightweight rocket powered aircraft.

The need for ethanol, which was boosted by World War I, fell when cheap crude oil came into play.

In the 1970s, the oil producing Arab nations imposed a ban on petroleum exports to countries backing Israel during the Yom Kippur War, which secured ethanol’s spot in the fuel lineup.

Brazil, leading the world, has at least 25% ethanol mixed into its fuel, and special ‘flex fuel’ cars can run on either pure ethanol or a blend.

In 2021, Ford introduced the first-ever hybrid electric flex fuel vehicle that can run on both a battery and E85 (which is 85% ethanol).

By 2024, the first commercial facility for converting ethanol to aviation fuel started operations in the U.S.

India, known for its abundant sugarcane production, began mixing 5% ethanol into petrol in the early 2000s.

Now, we’re up to 20%. While vehicles that can use E20 are being introduced, millions of older cars can’t handle this blend.

The thought of producing your own fuel is appealing, especially for a country like India. However we must consider the challenges of engine technology.

Ethanol has a wide range of applications

It serves as an antiseptic in medical wipes and hand sanitizers, it dissolves many medicines that don’t mix well with water, and it’s found in liquid pain medications, cough syrups, and cold medicines.

It helps keep medicines mixed and stable while also acting as a preservative.

Additionally, it’s used in mouthwashes, perfumes, deodorants, paints, and markers.
