Context:
Amid recurring global oil shocks, India is considering an aggressive ethanol blending strategy (E30/E100) and promotion of flex-fuel vehicles to reduce import dependence and enhance sustainability.
Key Highlights:
- Ethanol Blending Progress
- Achieved 19.2% blending in petrol in 2024–25.
- Supplied 1,039 crore litres of ethanol to OMCs.
- Target: move beyond E20 to E30/E100 fuels.
- Feedstock Diversification
- Expanded from C-heavy molasses to:
- B-heavy molasses
- Sugarcane juice/syrup
- Rice, maize, damaged foodgrains
- Supply Contracts
- OMCs contracted 1,058 crore litres:
- 766 crore litres from grains
- 292 crore litres from sugarcane-based sources
- Policy Recommendations
- Increase blending mandate to 30%.
- Promote flex-fuel vehicles (FFVs) and conversion kits.
- Bring ethanol fuels under GST regime for tax rationalization.
- Global Benchmark
- Brazil’s Proalcool Programme (1975) cited as a successful model.
Relevant Prelims Points:
- Ethanol Blending:
- Mixing ethanol with petrol (e.g., E20 = 20% ethanol).
- Reduces carbon emissions and fossil fuel dependence.
- Flex-Fuel Vehicles (FFVs):
- Can run on petrol, ethanol, or blends.
- Oil Marketing Companies (OMCs):
- Public sector firms like IOCL, BPCL, HPCL.
- Feedstocks for Ethanol:
- Sugarcane derivatives, grains, agricultural residues.
Relevant Mains Points:
- Energy Security:
- Reduces dependence on crude oil imports (~85% dependency).
- Insulates economy from oil price volatility and geopolitical shocks.
- Environmental Benefits:
- Lower GHG emissions compared to fossil fuels.
- Supports India’s climate commitments (NDCs).
- Economic & Agricultural Impact:
- Provides additional income to farmers.
- Utilizes surplus agricultural produce efficiently.
- Challenges:
- Competing demand for food vs fuel.
- Water-intensive crops like sugarcane raise sustainability concerns.
- Need for vehicle compatibility and infrastructure.
- Policy & Taxation Issues:
- Current tax structure disincentivizes ethanol adoption.
- Need for uniform GST framework.
- Way Forward:
- Promote second-generation (2G) ethanol from waste biomass.
- Encourage flex-fuel vehicle ecosystem.
- Balance food security and biofuel production.
- Rationalize taxation to incentivize ethanol fuels.
- Invest in R&D and infrastructure for biofuels.
