Ethanol Blending: A Key to Achieving Energy Independence

India's goal of achieving 90% flex-fuel vehicles, inspired by Brazil, faces hurdles despite reaching 15% ethanol blending in 2024. The Ethanol Blending Program has saved ₹1.01 lakh crore in foreign exchange, but concerns about food security arise due to crop diversion. The program's reliance on policy changes, along with climate uncertainties, calls for a thorough cost-benefit review before expanding flex-fuel adoption.

Current Status of Ethanol Blending in India

Introduction to Ethanol Blending

• Ethanol Overview: Ethanol, an alcohol made from fermenting sugars in crops like sugarcane, maize, and other biomass, is a widely used biofuel and industrial solvent.
• Ethanol Blending: The process of mixing ethanol with petrol to create a blended fuel, reducing petrol consumption, cutting down environmental pollution, and boosting the use of locally produced biofuels. It plays a key role in enhancing energy security and sustainability.

India’s Push for Ethanol Blending

• Strategic Goal: As the third-largest energy consumer globally, India aims to reduce reliance on oil imports by increasing ethanol blending in petrol. The Ethanol Blended Petrol (EBP) Programme has been pivotal in enhancing energy security while supporting rural economies.
• Policy Support: The government has reduced the Goods and Services Tax (GST) on ethanol to 5% and introduced interest subsidies to enhance production capacity, further bolstering the ethanol industry.

Why Ethanol Blending is Crucial for India’s Energy Transition
1. Enhancing Energy Security and Reducing Import Dependency

• High Import Reliance: India imports over 85% of its crude oil, exposing the nation to global price fluctuations and geopolitical risks, as seen with the Russia-Ukraine conflict and tensions in West Asia.
• Forex Savings: The ethanol blending program has already saved ₹1.06 lakh crore in foreign exchange by reducing oil imports.
• Future Potential: With the blending target of 20% by 2025, India could further reduce oil import dependency, saving billions annually.

• Increased Revenue for Farmers: The Ethanol Blended Petrol (EBP) program has provided direct payments of ₹87,558 crore to farmers and ₹1.45 lakh crore to distillers, offering a new revenue stream and alleviating the sugarcane arrears crisis.
• Private Sector Investment: The program has encouraged private investments, with distillers establishing ethanol production capacities of 16.2 billion liters by September 2024.
• Rural Economic Growth: The initiative has fostered rural employment and growth in the biofuel sector, benefiting local economies.

• Emission Reduction: Ethanol blending contributes to lower emissions, with E20 fuel reducing carbon monoxide emissions by 20%.
• Support for Climate Goals: India’s goal to reduce carbon intensity by 45% by 2030, as pledged at COP26, relies on programs like ethanol blending to meet environmental targets.
• CO2 Reduction: Blending has already reduced CO2 emissions by an estimated 544 lakh metric tons, supporting India's broader renewable energy strategy.

• Automobile and Technology Advancements: The ethanol push has prompted the development of flex-fuel engines, with GST concessions accelerating R&D in this area.
• Biotechnology and Chemical Industry Growth: The ethanol program has spurred growth in biotechnology, with second-generation ethanol plants and grain-based distilleries, creating new industrial ecosystems and employment opportunities.
• Sustainable Practices: New methods, such as using rice straw and corn cobs for second-generation ethanol, help address issues like stubble burning, promoting sustainable agriculture.

• Global Leadership: India's commitment to ethanol blending positions it as a leader in global climate discussions, while fostering cooperation with biofuel powerhouses like Brazil.
• International Partnerships: India’s role in the 2023 Global Biofuel Alliance enhances its standing in the global biofuel market, facilitating technology transfer and expertise sharing.
• Sustainable Development Leadership: India's biofuel strategy demonstrates its commitment to sustainable energy, attracting green investments and positioning India as a model for developing nations.

• Stable Market for Sugar: The guaranteed demand for ethanol stabilizes prices in the sugar sector, which has historically been volatile.
• Predictable Demand Curve: Ethanol blending creates a reliable demand for crops, enabling better agricultural planning and helping farmers make informed decisions.
• Certainty for Investments: The fixed pricing model ensures a stable investment environment, providing confidence in the sector despite differences from Brazil’s market-driven approach.

Key Issues Associated with Ethanol Blending in India
1. Food Security vs. Fuel Production

• Sugar Diversion: The government lifted the cap on sugar diversion for ethanol production starting November 2024, intensifying the conflict between food and fuel production.
• Cane Juice Restrictions: In December 2023, a directive was issued to halt cane juice diversion for ethanol, highlighting the sensitive balance.
• Food Supply Strain: The expected rise in sugar consumption to 30 million tonnes in the 2024-25 season, combined with increasing ethanol diversion, raises concerns about food security. This issue is especially critical during poor monsoon years, affecting the program’s sustainability.

• High Water Demand: Sugarcane, the main feedstock for ethanol, consumes about 2,500 liters of water per kilogram of sugar.
• Groundwater Depletion: The expansion of sugarcane cultivation for ethanol has exacerbated groundwater depletion in states like Maharashtra and Uttar Pradesh.
• Water Footprint: Studies indicate that the water required for ethanol production in India ranges from 230-7,150 liters per liter of ethanol, depending on processing methods, further straining water resources.

• Administered Pricing: India's controlled ethanol pricing system creates inefficiencies compared to Brazil’s market-driven model.
• Price Adjustments: The increase in ethanol procurement prices (from ₹43-59 to ₹49-66 per liter between FY19 and FY23) places additional financial strain on Oil Marketing Companies (OMCs).
• Distorted Market: Differing pricing for sugarcane juice, B-heavy molasses, and grains creates market distortions, undermining the program’s economic efficiency.

• Maize Shortage: The diversion of maize for ethanol production has raised prices by 20%, affecting poultry and animal feed sectors.
• Supply Chain Disruption: The starch industry, reliant on maize, reports production cuts due to feedstock shortages.
• Export Decline: India's maize exports, traditionally between 2 to 4 million metric tonnes, are expected to fall dramatically in 2024, with projections of just 450,000 tonnes, while imports are set to rise.

• Water Pollution: Ethanol production has led to increased water pollution, despite the enforcement of zero liquid discharge norms at distilleries.
• Carbon Emissions: Life-cycle assessments reveal that the carbon footprint of ethanol production, including land-use changes and energy usage, offsets some of its emissions benefits. The electricity consumption in the production stage contributes 97.83% to the greenhouse gas emissions of ethanol production.
• Soil and Biodiversity Loss: Intensive sugarcane farming for ethanol has caused soil degradation and harmed biodiversity in agricultural regions.

• Vehicle Modifications: Current vehicles, not designed for higher ethanol blends like E20, require substantial modifications. These changes could lead to engine corrosion, damage to seals and gaskets, and reduced fuel efficiency.
• Consumer Resistance: With ethanol-blended fuels having lower energy content compared to pure petrol, consumer acceptance remains uncertain, complicating the adoption of higher ethanol blends.
