  • Ethanol Definition:
    • Ethanol is a key biofuel produced through the fermentation of sugars by yeasts or via petrochemical methods like ethylene hydration.
    • It is essentially 99.9% pure alcohol suitable for blending with petrol.
  • Ethanol Blending Programme (EBP):
    • The EBP is designed to:
      • Reduce the nation’s reliance on crude oil imports.
      • Decrease carbon emissions.
      • Enhance farmers’ incomes.
  • Blending Target:
    • The Indian government has expedited the goal for 20% ethanol blending in petrol (E20) to 2025, moving it up from the initial target of 2030.
  • Production Sources:
    • While primarily derived from extracting sugar from sugarcane, alternative organic sources like food grains can also be utilized for ethanol production.
  • Energy Consumption in India:
    • India ranks as the world’s 3rd largest energy-consuming nation, and a significant portion of its energy needs are fulfilled through oil imports.
  • Growth in Ethanol Production Capacity:
    • Over the past 8 years, India has witnessed a remarkable increase in ethanol production capacity, surging more than 2.5 times.
    • The number of distilleries in the country has also seen a substantial rise, growing by 66%.
  • Primary Source of Ethanol in India:
    • The majority of ethanol production in India is derived from B Heavy Molasses.
  • Progress in Ethanol Blending:
    • India has made significant strides in ethanol blending with petrol, doubling the percentage to 10% over the past two years.
  • Future Blending Targets:
    • The national target is set to achieve a 25% ethanol blending with petrol by 2025.
  • In sugarcane, ethanol is produced from molasses (C-heavy/B-heavy), minimally impacting sugar output.
  • Corn-based ethanol directly reduces its use as food or livestock feed, linking food prices to crude oil prices.
  • Sugarcane is the preferred choice in tropical countries like Brazil and India due to higher yields.
  • While using sugarcane has environmental and hunger-related impacts, appropriate land-use policies can regulate these effects.
  • Enhanced Energy Security:
    • Mitigates the import bill, saving around Rs 30,000 crore annually in foreign exchange.
    • Contributes to reduced carbon emissions, aligning with environmental sustainability goals.
  • Income Boost for Farmers:
    • Diversification of ethanol feedstock (rice, maize, jowar, etc.) leads to increased income for farmers.
    • Aligns with the recommendations of the Ashok Dalwai committee to double farmers’ income through farm diversification.
  • Reduced Petroleum Dependency:
    • By blending ethanol with gasoline, it lowers the amount of petrol needed for vehicle operation, diminishing reliance on imported, expensive, and environmentally harmful petroleum.
    • Presently, India imports 85% of its oil requirements.
  • Cost Savings:
    • India’s net petroleum import in 2020-21 was 185 million tonnes, costing USD 551 billion.
    • With the majority of petroleum products utilized in transportation, the E20 program has the potential to save the country USD 4 billion annually.
  • Environmental Benefits:
    • Ethanol serves as a cleaner fuel, providing comparable efficiency to petrol but at a reduced cost.
    • Factors such as extensive arable land, increasing production of food grains and sugarcane leading to surpluses, available technology for ethanol production from plant-based sources, and the feasibility of adapting vehicles to ethanol blended petrol (EBP) support the roadmap for E20.
  • Strategic Importance:
    • The E20 target is viewed not just as a national imperative but also as a crucial strategic requirement.
  • Utilization of Valuable By-Products:
    • Molasses-based distilleries yield approximately 28% of potash, usable as fertilizer.
    • By-products can be sold as animal feed, adding economic value.
  • Job Creation Through Technology Adoption:
    • Integration of new technology in ethanol production facilitates additional employment opportunities.
  • Sustainability Measures:
    • Ethanol production from damaged food grains and vegetable waste ensures sustainability without compromising food security.
  • The NITI Aayog released a report on ‘Roadmap for Ethanol Blending in India 2020-25’ in June 2021.
  • Major goals proposed by the report:
    • Increase pan-India ethanol production capacity from 700 to 1500 crore liters.
    • Phased rollout of E10 fuel by April 2022.
    • Phased rollout of E20 starting from April 2023, with the goal of achieving availability by April 2025.
    • Initiate the rollout of E20 material-compliant and E10 engine-tuned vehicles from April 2023.
    • Begin production of E20-tuned engine vehicles from April 2025.
    • Encourage the cultivation of water-sparing crops, such as maize, for ethanol production.
    • Promote the use of technology for ethanol production from non-food feedstock.
  • GST Reduction: Goods & Service Tax (GST) on ethanol for the EBP Program has been reduced from 18% to 5%.
  • Interest Subvention Scheme: Implemented to enhance ethanol production capacity and facilitate year-round production.
  • Roadmap 2020-25: Niti Aayog’s released roadmap recommends measures for ethanol blending, aligning with targets set in the EBP Program.
  • Ethanol Procurement: The government permits ethanol procurement from sugar cane, surplus rice, and maize through the Food Corporation of India.
  • EBP Program: Launched in 2003, the Ethanol Blended Petrol (EBP) Program aims to boost renewable fuel usage, starting with 5% blending. The target is 10% by 2022 and 20% (E20) by 2025-26.
  • National Biofuels Policy: Introduced in 2018, the policy sets a target of 5% biodiesel blending in diesel by 2030.
  • Differential Pricing: The government has established higher prices for ethanol produced from B-heavy molasses and whole sugarcane syrup, compensating mills for reduced or nil sugar production.
  • Ethanol Blending Challenge:
    • India faces a delicate situation in achieving its ethanol blending target.
    • The 20% ethanol blending target for 2025 encounters obstacles due to:
      • Low sugar stocks in 2022-23.
