Ethanol blended petrol could really be viable fuel option for India. Here's how

Ethanol emits fewer pollutants than fossil fuels such as petrol or diesel.India currently blends 8.5% ethanol in motor fuel, which is to grow to 20% by 2023.

The Indian government has issued the draft notification on ethanol blending in the petrol just a few days ago. This draft notification proposes 12% and 15% ethanol blending in petrol as automotive fuels, which will be available as E-12 and E-15 respectively.

The draft notification was issued in line with Prime Minister Narendra Modi's announcement of advancing the deadline for 20% ethanol blending by 2025 from 2030. The notification comes at a time when several cities across the country are witnessing both petrol and diesel being sold at all-time high prices.

Petrol prices have breached 100 per litre mark in several cities, while diesel too has breached the same milestone at places. Several other cities are ready to reach the century milestone in a few days.

The Indian government has been pushing electric mobility for quite some time. However, there are challenges for e-mobility. The industry has been voicing that and considering that the stakeholders are advocating the need for other greener fuel solutions like CNG, biofuels alongside electrification. Usage of biofuel appears to be a viable solution, but not explored to the fullest in India.

In foreign markets such as Brazil and the US, ethanol is used significantly as an alternative fuel solution. The ratio of ethanol blending in petrol is high in these two countries. India too now aims to explore the potential of ethanol blending in petrol. Currently, India uses fuel with an 8.5% blend of ethanol. This is said to go up to 20% by 2023.

What is ethanol?

Ethanol is a biofuel that is derived from the fermentation of sugarcane and corn. mainly made from molasses, ethanol acts as an alternative fuel solution to conventional petrol and diesel. It doesn't emit any particulate matter into the air.

Burning ethanol emits carbon monoxide, carbon dioxide, water and formaldehyde. Most of the vehicles come with the technology to oxygenate carbon monoxide and carbon dioxide. This fuel reduces nitrogen oxide emissions compared to fossil fuels. This way, ethanol is cleaner and a renewable energy source.

How ethanol-blended petrol can be beneficial for India?

Farming sector to be stronger - India is one of the largest sugarcane producers in the world. It was the second-largest sugarcane producer globally, next to Brazil. According to Union Road and Transport Minister Nitin Gadkari, sugarcane production in India in 2018 was surplus by 50-60 lakh tonnes. With such significant sugarcane production capacity, a chunk of it can be diverted for ethanol production. This would help the farmers.

Cheaper fuel solution - A litre of ethanol is currently priced at 62.65 in India, compared to nearly 100 for a litre of petrol and above 90 for a litre of diesel. This means ethanol or ethanol-blended petrol will reduce the fuel cost of consumers significantly compared to pure fossil fuel vehicles.

Lesser dependency on fossil fuel - With ethanol policy implemented, Inia's fossil fuel dependency will be much lowered than now. India currently imports 80% of its fossil fuel requirement. This translates into a huge amount of fuel bill for the country. With ethanol-blended petrol, the fuel import bill would come down substantially.

Pollution reduction - With ethanol-blended petrol, the vehicular pollution level is expected to be reduced significantly. Ethanol is non-toxic, biodegradable fuel solution. It is safe to handle, store and transport as well. This oxygenated fuel contains 35% oxygen and emits fewer pollutants into the air than petrol or diesel.
