Notes

  • E20 fuel (20% ethanol blend) may cause a 3%-5% reduction in fuel economy for some vehicles.
  • Benefits of E20: Higher octane rating, superior anti-knock characteristics, faster combustion, better pickup, smoother acceleration, and cleaner engine operation.
  • Environmental impact: E20 reduces lifecycle carbon emissions by approximately 40%.
  • Pricing mechanism: E20 is currently costlier to produce than pure petrol when international crude oil prices are around $70 per barrel due to remunerative procurement prices for farmers (e.g., maize-based ethanol at ₹71.86/litre).
  • Economic threshold: Ethanol becomes more cost-effective than petrol when crude oil prices reach $120–$130 per barrel.
  • Strategic advantage: Ethanol blending insulates the Indian market against global oil price volatility and mitigates fuel price hikes.
  • Implementation timeline: A phased approach spanning two decades, involving pilot projects (2001), policy notifications (2013), institutional reforms (2018), and investments (2021).
