Amid E20 Row, First Talks Underway On Feasibility Of An E10 Option As Well, Pg7

Key Highlights:

• Discussions are underway within the government and industry regarding the feasibility of retailing E10 petrol alongside E20 fuel for older vehicles.
• India achieved 20% ethanol blending in petrol last year, five years ahead of its original deadline.
• Concerns have been raised about E20 fuel's impact on mileage and engine components in older, non-compliant vehicles.
• Chief Economic Adviser V Anantha Nageswaran has publicly advocated for offering lower ethanol blends like E10 as an additional option.

Detailed Insights:

• E20 fuel consists of 80% petrol and 20% ethanol, while E10 fuel contains 10% ethanol.
• Motorists and opposition leaders have questioned the lack of choice, as E20 is currently the only standard petrol variant sold.
• The government initially cited "enormous logistical challenges" and increased costs for offering multiple fuel grades across the country.
• Vehicles manufactured after April 2023 are considered E20-compliant under Bharat Stage 6 (BS6) phase two emission norms.
• Older vehicles, particularly those sold before 2023, were not originally designed for higher ethanol blends like E20.
• Introducing E10 in large volumes would require building an almost parallel supply chain and upgrading fuel retail infrastructure.
• The permissible life of a petrol vehicle in the National Capital Region is 15 years, indicating a large existing fleet of older vehicles.

Key Concepts Involved:

• E20 Fuel: A blend of 80% petrol and 20% ethanol, aimed at reducing crude oil imports and vehicular emissions.
• E10 Fuel: A blend of 90% petrol and 10% ethanol, generally considered compatible with most older vehicle engines.
• Ethanol Blending: The process of mixing ethanol, a biofuel, with petrol to create a blended fuel, promoting renewable energy.
• Bharat Stage (BS) Emission Norms: Standards instituted by the Indian government to regulate the output of air pollutants from internal combustion engines.
