Why in news
The Ministry of Information & Broadcasting issued a clarification regarding the moisture absorption properties of E20 fuel and its impact on older vehicle components.
Background
E20 fuel (20% ethanol blend) absorbs moisture more than pure petrol, potentially causing corrosion in older vehicles with aging seals. High-humidity locations like Cherrapunji increase this risk, while newer models like Honda Cars India (since 2009) are designed for E20 compatibility.
Facts for Prelims
- S&TE20 fuel: A blend of 20% ethanol and 80% gasoline.
- FactEthanol blends absorb more moisture than pure petrol, leading to potential corrosion of seals and hoses.
- PlaceCherrapunji: Identified as a high-humidity area where moisture-related fuel issues are more prevalent.
For Mains
Q. Discuss the challenges and opportunities associated with the transition to ethanol-blended fuels (E20) in India's transport sector.
Dimensions to cover in your answer
- infrastructure readiness
- impact on older vehicle fleets
- reduction in carbon footprint
- supply chain for ethanol
