Government Measures to Increase Ethanol Blending Beyond 20%: National Policy on Biofuels

Through the National Policy on Biofuels – 2018 which obtained amendments in 2022 the Government of India moved forward the target date for 20% ethanol blending in petrol from 2030 to Ethanol Supply Year (ESY) 2025-26. Higher ethanol blending requires enterprises to overcome technological barriers as well as environmental challenges while satisfying national regulatory standards since ethanol blending serves multiple strategic national objectives.

What is Ethanol Blending?

• Ethanol blending combines ethanol and petrol into one mixture for decreasing fossil fuel dependency while decreasing pollution while encouraging renewable energy adoption. 

• The Indian government has established a target to reach 20% ethanol mixed gasoline (E20) by the 2025-26 Ethanol Supply Year. 

• Ethanol manufacturers produce their supply mainly through the fermentation of sugarcane and maize together with agricultural waste materials. 

• Ethanol blending has achieved three crucial benefits for the country which include lower dependence on foreign oil and reduced carbon footprint as well as higher agricultural revenue streams for farmers.

Ethanol Blending Progress

• The achievement of 10% ethanol-petrol blending occurred five months earlier than expected when measured in June 2022.

• 12.06% blending in ESY 2022-23.

• 14.60% blending in ESY 2023-24.

• The ethanol blending rate reached 17.98% during the second half of the financial year 2024-25 on February 28th.

• The government has not taken an official decision to surpass blending ethanol beyond 20%.

Roadmap for Ethanol Blending in India (2020-25)

• The adoption of E20 fuel demonstrates minor enhancement of fuel consumption in E10-compatible vehicles when combined with necessary engine adjustments.

• The Society of Indian Automobile Manufacturers through SIAM concluded that appropriate engine optimization along with hardware alterations makes efficiency reduction manageable.

• Engines using E20 fuel demonstrated no considerable effects on their operational performance or deterioration in oil quality or wear on engine components.

Feedstock Diversification

• The National Policy on Biofuels has established a framework which enables different resource materials for biofuels production including:

• The National Biofuel Coordination Committee determines food grain abundances to announce surplus periods for usage.

• The fuel mixture consists of sugarcane juice together with molasses and maize supplemented by damaged food grains which include broken rice and rotten potatoes etc.

• Agricultural residues (rice straw, cotton stalk, corn cobs, sawdust, bagasse, etc.).

• The procedure for sugarcane and maize diversion operates with input from various relevant stakeholders.

Government Initiatives Since 2014

• Expanded feedstock sources for ethanol production.

• The Ethanol Blended Petrol (EBP) Program follows the administered pricing system for procuring ethanol.

• The government introduced a 5% GST rate for ethanol that can be used during blending operations.

• The government modified the Industries (Development and Regulation) Act to achieve easier ethanol movement between states.

• Simplified procurement process by Public Sector Oil Marketing Companies (OMCs).

• The EISS program (2018-22) introduced by the government provided financial support to ethanol-production facilities.

• Cost-effective procurement of ethanol occurs through Long-Term Offtake Agreements that Public Sector Oil Marketing Companies establish with Dedicated Ethanol Plants.

Current Status of Ethanol Blending in India

Economic and Environmental Impact

• Ethanol-blended fuel now occupies 15% of the market (2024) with plans to reach 20% by 2025 starting from the initial level of 1.53% in 2014.

• The nation saved 1.06 lakh billion rupees of foreign exchange due to decreased oil imports.

• Reduced CO₂ emissions by 544 lakh metric tons.

• The newly developed revenue channels through this program directly benefited farmers while simultaneously decreasing their overdue sugarcane payments.

• Private investments in the ethanol sector continue to grow as the production capacity exceeds 1623 crore litres by September 2024.

Challenges in Ethanol Blending Expansion

• Food Security vs. Fuel Production

  • The expansion of ethanol-production from sugar reduces available domestic sugar quantities.

  • The projected consumption of sugar in India stands at 30 million tonnes for the next fiscal year 2024-2025.

• Water Resource Strain

  • Every kilogram of sugar in sugarcane needs 2,500 liters of water.

  • Manufacturing ethanol through existing processes involves significant water consumption which ranges between 230 to 7,150 liters for each liter of produced ethanol substance.

• Economic Viability and Pricing

  • Ethanol pricing in India relies on government management rather than the free market mechanism used by Brazil.

  • Ethanol distributors paid between INR 49-66 per liter in the fiscal year of 2023 whereas they originally paid between INR 43-59 per liter in the fiscal year of 2019.

• Impact on Other Industries

  • The diversion of maize production towards alternative uses caused the poultry feed and starch industries to increase their maize costs by 20 percent.

  • The quantity of exported maize dropped from 4 million metric tonnes (2023) to 450,000 tonnes (2024).

• Environmental Trade-offs

  • Water pollution from distilleries and increased GHG emissions during ethanol production.

  • The production process of anhydrous ethanol results in 123.10 kg CO₂-eq emissions for each kilogram produced according to scientific research.

• Technological and Vehicle Compatibility

  • Customers who fill up their engines with E20 fuel should be aware that it can create corrosion problems and performance decreases in vehicles without proper compatibility.

  • The adoption of flex-fuel vehicles needs both government incentives and upgrades of necessary infrastructure.

Recommended Steps to Boost Ethanol Blending

• Diversification of Feedstock Sources

  • The implementation of second-generation (2G) ethanol production from agricultural materials including rice straw and corn cobs should be promoted.

  • The establishment of crop residue collection points should aim to stop farmers from setting fires to dispose of their agricultural waste.

  • Government support of Public-Private Partnership (PPP) agreements should establish 2G ethanol facilities just like Panipat’s 100-milliliter daily paddy straw plant.

• Infrastructure Development

  • Ethanol pipelines must connect production zones with consumption areas to boost efficient transportation.

  • The establishment of storage facilities across ethanol production areas must have anti-corrosive measures built-in.

  • Ethanol-specific railway wagons combined with emergency storage facilities should be established to function effectively.

• Technology and Research Support
