E20 Fuel May Reduce Fuel Economy by 2–6%: Government
Context
The Union Government has informed Parliament that E20 fuel (petrol blended with 20% ethanol) may lower fuel economy by 2–6%, depending on the vehicle’s type and age. However, it has clarified that the blend offers environmental benefits and has not raised concerns regarding engine durability.
Key Highlights
- Extensive road and engine trials conducted by agencies such as ARAI, SIAM and Indian Oil Corporation (IOCL) found no significant durability or performance issues associated with the use of E20 fuel.
- Although vehicles may experience a 2–6% reduction in mileage, E20 fuel offers improved combustion efficiency and enhanced acceleration characteristics.
- Carbon monoxide emissions from E20 are estimated to be around 30% lower than those from E10 fuel, contributing to cleaner vehicular emissions.
- A higher ethanol blend promotes more complete combustion, thereby reducing overall air pollution from transport.
- The adoption of E20 aligns with India’s broader objective of reducing crude oil imports, improving energy security and lowering greenhouse gas emissions.
Key Concepts
- E20 fuel is a petrol blend containing 20% ethanol and 80% petrol by volume.
- The National Policy on Biofuels, 2018 encourages ethanol blending to enhance energy security, promote cleaner fuels and reduce dependence on fossil fuels.
- India has achieved its 20% ethanol blending target ahead of schedule under the Ethanol Blended Petrol (EBP) Programme.
- Ethanol used for blending is primarily produced from sugarcane, maize and other agricultural feedstocks, providing additional income opportunities for farmers.
- Increasing ethanol blending supports energy diversification, reduces fossil fuel consumption and contributes to India’s climate and sustainability goals.
Way Forward
Expand the availability of E20-compatible vehicles and fuel infrastructure, promote diversified and sustainable ethanol feedstocks, encourage advanced biofuel technologies, and ensure that environmental gains are balanced with vehicle performance and fuel-efficiency considerations.
