On ethanol fuel, move slower — with a plan

The Centre is apparently going slow on implementing ethanol blending in petrol beyond the current 20 per cent. The rethink, as reported by this newspaper, comes even as the Finance Ministry, only last month, exempted petrol containing 22, 25, 27 and 30 per cent ethanol from excise duty after the Bureau of Indian Standards had issued specifications for these higher blends. The move to not hurry the transition to 20 per cent-plus blends makes sense. The all-India average ethanol-petrol blending ratio rose from 5 to 10 per cent between 2019-20 and 2021-22. It has since further doubled to 20 per cent, with this blend (E20) being made mandatory for all petrol sold from April 2026. Given how fast it has happened — well before the originally planned 2030 deadline — a pause isn’t a bad thing from a policy or practical standpoint.

The pause period should be used by the government to address genuine concerns of motorists. The first has to do with lower mileage because of ethanol’s calorific value being 30-35 per cent less compared to that of pure petrol. The second is on account of ethanol’s hygroscopic (moisture-absorbing) property, which can lead to corrosion of steel fuel tanks and internal metal components. As it is, only vehicles sold in India after April 2023 have full material compatibility with E20. Handling fuel with ethanol blends may require major overhaul of internal combustion engines and auto parts to resist any potential ethanol-related degradation. Not surprisingly, it’s the older car and two-wheeler owners who are feeling short-changed; reduced mileage and wearing of engine parts from ethanol is something they were not told about at the time of purchase before April 2023. All the more reason for transparent communication before embarking on E25 or E30. The government can even consider fiscal measures that would make the higher ethanol-blended fuels cheaper than E20, which will make consumers more receptive to them.

That said, the focus on biofuels and electrification of transport must continue. The risks of 90 per cent crude petroleum import dependency are too high — and the Iran war will not be the last of the global oil supply shocks. India needs a clear, calibrated and forward-looking roadmap for higher ethanol blends that avoid the abruptness of the earlier rollouts. Equally important is the feedstock for producing ethanol. It’s certainly not desirable to make ethanol from water-guzzling rice. More effort is required to promote sweet sorghum, bajra and other millets as sustainable feedstocks, with breeding of varieties/hybrids with higher starch content and fermentation efficiencies comparable to maize or sugarcane.

Overall Analysis

The editorial argues that while India’s ethanol blending programme is an important step towards energy security and reducing dependence on imported crude oil, the government should avoid rushing into higher ethanol blends without adequate preparation. The central message is that good policy is not just about ambitious targets but also about careful implementation, transparency, and public confidence.

The editorial opens by appreciating the Centre’s decision to slow down the transition beyond the current 20% ethanol blending (E20). The author adopts a balanced approach by acknowledging that India has already achieved its blending targets much earlier than expected. Rather than criticizing the government, the writer suggests that a temporary pause is a sensible policy decision because rapid implementation should be followed by careful assessment. This measured beginning establishes a rational and objective tone.

The discussion then shifts to the practical concerns faced by consumers. The editorial explains that ethanol has a lower energy content than petrol, leading to reduced fuel efficiency, and its moisture-absorbing nature may damage fuel tanks and engine components, especially in older vehicles. The author highlights that many vehicle owners purchased their cars or two-wheelers before manufacturers informed them about ethanol compatibility. By using expressions like “feeling short-changed” and emphasizing transparent communication, the writer brings the consumer’s perspective into the debate. Instead of opposing ethanol blending, the editorial advocates informed consent, proper awareness campaigns, and financial incentives that make higher ethanol blends more acceptable.

In the final section, the editorial broadens the discussion to India’s long-term energy strategy. It strongly supports continued investment in biofuels and electric mobility, arguing that India’s heavy dependence on imported crude oil makes diversification unavoidable. At the same time, it cautions against producing ethanol from water-intensive crops like rice, recommending sustainable alternatives such as millets and sweet sorghum. The conclusion reflects the editorial’s larger philosophy that environmental sustainability, consumer interests, and energy security should advance together through careful planning rather than hurried implementation.

Overall, the editorial combines economic reasoning, environmental concerns, consumer welfare, and policy analysis to argue that successful reforms require both speed and sensitivity.

Conclusion & Tone

The editorial supports India’s transition towards cleaner fuels but argues that policy success depends on thoughtful execution rather than rapid implementation alone. It urges the government to address consumer concerns, improve transparency, promote sustainable feedstocks, and adopt a phased roadmap for higher ethanol blending.

Tone: Analytical, balanced, constructive, and policy-oriented.
