Overview
The Union Minister of Nitin Gadkari announced that India should aim for E100 in the near future. The move is part of a broader strategy to make the country self‑reliant in energy and to meet stricter emission norms under CAFE III.
Key Developments
- India currently allows petrol engines up to E20 (20% ethanol). Higher blends such as E85 or E100 need flex‑fuel vehicles.
- Brazil has long used flex‑fuel cars; India’s only example is Toyota’s Hycross Innova, priced Rs 3‑4 lakh above the conventional model. Maruti Suzuki and Hyundai are developing prototypes for launch between FY26‑FY28.
- The government is promoting second‑generation ethanol to avoid competition with food crops and to reduce crop‑residue burning.
- National Green Hydrogen Mission targets hydrogen at $1 kg to make India a future exporter.
- CAFE III, effective from 1 April 2027, will cut fleet‑wide CO₂ targets by about 30% compared with CAFE II, creating a policy push for higher ethanol blends.
Important Facts
• Ethanol currently comes mainly from sugarcane, a water‑intensive crop grown in water‑stressed regions like Maharashtra. • Energy density of ethanol is lower; one litre of petrol gives 45‑55% more energy than one litre of ethanol. • E20 fuel reduces mileage by 6‑7% compared with pure petrol, raising running costs for consumers. • Government‑administered pricing keeps ethanol competitive with petrol, but production costs remain high.
