Rudolph Diesel himself developed biodiesel in 1890, wherein pure vegetable oils were used in diesel engines for agriculture, where petroleum diesel was not available. Modern biodiesel fuel is an outcome of research conducted in 1930s in Belgium, which is made by converting vegetable oils into compounds called fatty acid methyl esters. Process of trans-esterification was used to convert vegetable oils into fatty acid alkyl esters and use as diesel fuel replacement with lower viscosity of vegetable oil. Biodiesel is the trade name of fatty acid methyl esters. Concerns over environment, energy security and use of agro products brought the use of vegetable oils to the forefront.
Biodiesel is being used Worldwide now, due to concerns over Global warming. The future of biodiesel lies in the world’s ability to produce renewable feedstock’s such as vegetable oils and fats to keep the cost of biodiesel competitive with petroleum. Biodiesel is a fuel manufactured from non-edible vegetable oils, used cooking oil and animal fat. The fuel typically contains different types of Fatty Acid Alkyl (Methyl / Ethyl) Esters, conforming to BIS specification IS 15607 :2016.
The main benefit of biodiesel is that it can be described as ‘carbon neutral’. This means that the fuel produces no net output of carbon in the form of carbon dioxide (CO2). This effect occurs because when the oil crop grows it absorbs the same amount of CO2 as is released when the fuel is combusted.
