Government of India recently preponed the target to bring the average ethanol blending of petrol in the country to 20 percent by 2025. GOI plans to roll out the ethanol blended E20 petrol from April 2023. E20 fuel is 80 percent of petrol mixed with 20 percent of ethanol.
Around half of the petrol currently sold in in India contains 10 percent ethanol (E10). The rest being sold is unblended (E0). Under the first phase of the program, government targets to make E10 fuel available all over the country by April, 2022.
This policy push has several benefits. It is expected to reduce air pollution as ethanol fuel is lesser polluting than petrol. The government expects an annual savings of around Rs. 30,000 crores on oil import.
Ethanol fuel is ethyl alcohol which is a type of alcohol found in alcoholic drinks.
Petrol has more energy than ethanol; a tank full of ethanol contains approximately 30 percent less energy than the same amount of petrol.
