NEWS: Ethanol blending helps energy security BUT creates risks for food security. The Economic Survey flags a trade-off between Aatmanirbharta in energy and Aatmanirbharta in food
Background
- Ethanol blending means mixing ethanol (an alcohol-based fuel) with petrol to reduce fossil fuel use.
- India’s target: Blend 20% ethanol in petrol (E20) by 2025-26. Earlier target: 2030 → advanced to 2025-26
Government’s Arguments for E20
- Economic savings: $10 billion/year stays in India (less oil import).
- Raw material sources: C-heavy molasses (by-product of sugar industry, not used for sugar production).
- Broken rice (stocked in FCI godowns, otherwise wasted).
- Maize (less water-demanding crop compared to sugarcane).
- Food security concerns addressed: Uses mainly non-food or surplus products.
- Environmental goal: Lower carbon emissions compared to pure petrol.
Concerns & Challenges
- Uneven benefits: More gain for sugarcane farmers, distillers, traders; not all farmers benefit equally.
- Food security risk: Once ethanol economy is entrenched, hard to prioritise food stocks in shortages.
- Hidden imports: Fertilizers for ethanol crops cost ~$10 billion in forex → offsets import savings.
- Efficiency penalty: Ethanol has lower energy content → reduced mileage.
- Corrosion risk: Can affect durability of fuel handling systems.
- Lack of full disclosure from automakers on older model compatibility.
Government & Industry Actions
- Two ethanol-specific fuel quality norms already in place.
- India planning E27 norm, inspired by Brazil.
- Automakers now announcing flex-fuel models (can run on any ethanol ratio).
- Government claims research shows “no harm” — but editorial stresses transparency & consumer protection.
Way Forward
- Crop diversification planning
- Protection of nutritionally critical crops
- Ethanol feedstock diversification (nonfood biomass, 2G ethanol)
- Strong price & procurement support for pulses and oilseeds
