India's ethanol blending program has saved roughly Rs 1.9 lakh crore on crude oil imports and cut emissions by about 930 lakh tonnes of CO2 equivalent, according to former IOCL chairman B Ashok. The initiative also boosted farmer incomes by around Rs 1,60,000 crore. Ashok addressed common myths about E20 fuel, saying scientific studies and field tests show no damage to engines or significant loss in mileage. He noted that auto manufacturers and insurers have confirmed warranties remain valid with E20 use. The program blends ethanol from sugarcane and other biomass into petrol, reducing the need for imported oil while supporting domestic agriculture. Ashok dismissed claims that ethanol attracts insects or harms vehicle performance, pointing to tests covering up to 40,000 km on passenger cars and 20,000 km on two wheelers. The article frames ethanol blending as a triple win for energy security, farmer incomes, and emissions reduction, though it does not discuss potential trade offs like land use or water demand for feedstock.

India's ethanol blending numbers are big. Rs 1.9 lakh crore saved on oil imports and 930 lakh tonnes CO2 cut. That is real scale. But I wonder how much of that ethanol comes from sugarcane versus other feedstocks. Water use for sugarcane is high in a water stressed country.

The farmer income figure of Rs 1,60,000 crore is interesting. That is a lot of money going to rural areas. But is that net after input costs? And does the program rely on subsidies to keep ethanol prices competitive with petrol? Would like to see the full cost benefit breakdown.

930 lakh tonnes CO2 equivalent is a big number. But I want to know the lifecycle accounting. Does that include emissions from fertilizer and transport for sugarcane? Also, ethanol from molasses has different carbon intensity than from grain. The article does not specify the feedstock mix.

The article says E20 does not affect mileage significantly. That is a common concern for drivers. If the tests hold up in real world conditions, it removes a big barrier to adoption. But I would like to see independent verification from consumer groups, not just industry sources.

The policy angle here is interesting. India is using ethanol blending to reduce oil imports and cut emissions at the same time. But the carbon accounting needs to be transparent. If the ethanol is from sugarcane grown with heavy fertilizer and irrigation, the net climate benefit may be smaller than claimed. Also, the program competes with food crops for land.
