BPCL denied reports of reverting to E10 petrol from E20, reaffirming commitment to India's ethanol blending program which reduces pollution, boosts rural economy, and cuts fuel imports.

Key points

E20 petrol, containing 20% ethanol, is now India's standard fuel blend as part of the National Ethanol Blending Programme to reduce emissions and foreign exchange outgo.

BPCL Chairman clarified there's no proposal to replace E20 with E10, countering reports suggesting a rollback for older vehicles, emphasizing 3+ years of field data shows no engine damage.

The ethanol blending program aims for 20% blending by 2025 (now achieved) to cut crude imports (saves ~₹30,000 crore annually) and reduce CO2 emissions by ~10 million tonnes yearly.

[GS3-Environment] Higher ethanol blends like E20 contribute to India's Nationally Determined Contributions under Paris Agreement by reducing vehicular emissions and promoting biofuels.

Fuel efficiency concerns exist as ethanol has 30% lower energy density than petrol, causing 3-5% mileage drop in E10-designed vehicles using E20, per Petroleum Ministry data.

Proposed 95-octane E10 premium petrol would leverage existing infrastructure without separate supply chains, addressing older vehicle concerns while maintaining blending targets.

[GS3-Economy] The program boosts rural incomes by creating demand for sugarcane/molasses-based ethanol, with 500+ distilleries contracted to supply OMCs under government-fixed pricing.

Way Forward: India should invest in flex-fuel vehicle technology, standardize ethanol blends globally, and create public awareness campaigns about ethanol-blended petrol's benefits and compatibility.

Key terms

National Ethanol Blending Programme

Launched in 2003, this program mandates blending ethanol with petrol to reduce crude oil imports, cut emissions, and support sugarcane farmers. It achieved 10% blending (E10) nationwide by 2022 and 20% (E20) by 2025, making India among the fastest adopters globally.

E20 Fuel

Petrol blended with 20% ethanol, now India's standard automotive fuel. Ethanol is derived mainly from sugarcane/molasses, reducing greenhouse gas emissions by ~30% compared to pure petrol while supporting agricultural economies.

95-Octane Petrol

Premium grade petrol with higher resistance to engine knocking (higher Research Octane Number). In India, marketed as XP95 (IOC), SPEED (BPCL) and Power95 (HPCL), it constitutes ~15% of petrol sales and could serve as E10 carrier fuel for older vehicles.

Flex-Fuel Vehicles

Vehicles designed to run on varying ethanol blends (up to E85). Mandated in Brazil and the US, these require modified engines and fuel systems. India's auto industry is gradually adopting this technology to support higher ethanol blending targets.
