E20 Ethanol Blending

Context:

India has achieved the 20% ethanol blending (E20) target in 2025, five years ahead of the original target under the National Policy on Biofuels.

Ethanol Blending in India

  • Historical Progress: Ethanol blending rose from 5% in 2014 to 20% in 2025, supported by strong fiscal incentives to the sugarcane industry.
  • Government Claim: Achieved multiple objectives — reducing greenhouse gas emissions, enhancing farmers’ incomes, and lowering oil import bill.
  • Savings: Since 2014–15, India has saved ?1.40 lakh crore in foreign exchange through petrol substitution.

Consumer Perspective

  • Vehicle Compatibility: All vehicles sold from 2023 carry E20 compatibility stickers. Older vehicles require modifications (rubbers, elastomers, plastic components).
  • Public Reaction: According to LocalCircles survey, two-thirds of petrol vehicle owners oppose E20 citing lower mileage and higher maintenance costs.
  • Government Stand: Admits marginal drop in efficiency, which can be minimized through engine tuning and material compatibility.
  • NITI Aayog’s Suggestion: Proposed tax incentives on E10 and E20 fuels to compensate consumers.

Agriculture and Environmental Concerns

  • Sugarcane Dependence:
    • Ethanol supply increased from 40 crore litres (2014) to 670 crore litres (2024), using ~9% of sugar output.
    • Farmers received ?1.20 lakh crore payments since 2015.
  • Water Stress:
    • 60–70 tonnes of water needed per tonne of sugarcane.
    • Maharashtra’s sugarcane districts over-extract groundwater (CGWB 2023 report).
    • Land degradation: 30% of India’s land degraded (ISRO’s Desertification & Land Degradation Atlas, 2021).
  • Diversification Efforts:
    • FCI allocated 2 MMT rice for ethanol (2025), up from <3000 tonnes earlier.
    • 34% of corn output diverted to ethanol (2024–25), leading to 7 lakh tonnes corn imports.
    • OECD–FAO projects 22% of India’s sugarcane for ethanol by 2034.

Economic and Trade Dimensions

    • PSU Dividend Issue: Despite a 65% fall in oil prices, IOC & BPCL only reduced petrol prices by 2% while dividend payouts rose 255%.
    • US Pressure: The S. has pushed India to relax ethanol import restrictions; India has resisted citing domestic investment in ethanol industry.

Ethanol vs EV Transition

  • EV Advantage:
    • EVs have greater potential for emission reduction and faster decarbonisation of transport.
    • India’s EV share was 6% in 2024, needs to rise to 30% by 2030.
  • Rare Earth Challenge:
    • EV manufacturing dependent on REEs, largely imported from China.
    • India imported 2,270 tonnes REEs (2023–24); supply disruption led to reduced EV production plans (e.g., Maruti e-Vitara).

Way Forward

  • Consumer-Centric Approach: Introduce tax rebates/subsidies for ethanol-blended fuels to offset efficiency loss.
  • Sustainable Agriculture: Diversify ethanol feedstock to less water-intensive crops (maize, sorghum, agricultural residues); promote 2G ethanol technologies.
  • Balanced Energy Transition: Ethanol blending must complement, not substitute, the long-term EV transition.
  • Trade Safeguards: Maintain import restrictions on ethanol to protect domestic producers.
  • Water Governance: Strict groundwater extraction norms in sugarcane-growing states.
  • EV Supply Chain: Develop indigenous rare earth processing capacity; invest in battery recycling and alternatives to reduce import dependence.

Ethanol Blending Programme (EBP)

  • Launched: 2003; scaled up significantly after 2014.
  • Objective: To blend ethanol with petrol to reduce fossil fuel dependence, save foreign exchange, and cut carbon emissions.
  • Target:
    • 10% blending achieved in June 2022 (ahead of target of Nov 2022).
    • 20% blending target by 2025-26 (advanced from 2030).
  • Feedstock for ethanol: Sugarcane-based (molasses, sugar, juice, B-heavy molasses) and non-sugarcane-based (damaged food grains, maize, surplus rice from FCI).
  • Benefits:
    • Reduces crude oil imports (saves ~?41,500 crore forex in 2022).
    • Boosts farmers’ income (diversion of surplus grains/sugar).
    • Lowers vehicular emissions (CO? reduction).
    • Creates rural employment and investment in distilleries.

National Policy on Biofuels (2018, amended 2022)

Aim: Promote biofuels for energy security, farmers’ welfare, and environmental sustainability.

Types of biofuels:

  • 1G biofuels: Ethanol from sugarcane juice, molasses, starch, grains.
  • 2G biofuels: Ethanol from lignocellulosic biomass, agricultural residues.
  • 3G biofuels: From algae and industrial waste.
  • Drop-in fuels: Bio-CNG, green diesel, green aviation fuel.

Salient Features:

  • Widening of feedstock base for ethanol production.
  • Advancement of 20% ethanol blending target to 2025-26.
  • Encourages 2G ethanol to reduce stubble burning and air pollution.
  • Viability gap funding and tax incentives for 2G ethanol projects.
  • Promotes Bio-CNG and SAF (Sustainable Aviation Fuel).
  • Boost to waste-to-energy projects (municipal solid waste, biomass).
