Flex-Fuel Vehicles

Context: The government has advised carmakers to start making Flex Fuel Strong Hybrid Electric Vehicles (FFSHEV).

About Flex Fuel Vehicles (FFV)

  • Flex fuel vehicles (FFV) are capable of running on 100% petrol or 100% bio-ethanol or a combination of both.
  • Flex Fuel Strong Hybrid Electric Vehicles (FFSHEV) essentially houses an electric motor which powers the vehicle alongside the traditional petrol engine.
  • However, such vehicles are yet to be made widely available in world markets.
  • Dual fuel vehicle means the engine uses two fuels (gas and diesel) at the same time
  • Bi Fuel means the engine could run on either fuel separately.
  • Flex Fuel Vehicles (FFV) is capable of running on either petrol or ethanol or a combination of both hence it is a synthesis of Dual fuel vehicle and Bi fuel vehicle.

How much blending is being done presently?

  • Bio-ethanol contains less energy per litre than petrol
  • However, the calorific value will become on par with petrol with use of advanced technology.
  • A litre of petrol sold in India has an average of 8% ethanol content even though oil marketing companies have clearance to do 10% (E10) blending.
  • All vehicles manufactured in India are tuned for E10. They will not be able to run on higher ethanol content beyond 10%.

Why factors are pushing government to promote Flex Fuel Vehicles?

  • Reduce Import Bill: In FY21 India’s oil import bill stood at $62.7 billion. The government is desperate to bring down the oil import bill by creating fuel substitutes like ethanol, hydrogen and electricity.
  • Savings: Even a push till the E20 level (20% blending) can result in savings of $4 billion per annum. This is possible only if flex-fuel vehicles are made available in the market.
  • Paris Climate Commitments: Also, FFVs will also help the government meet its commitments when it comes to reducing emission. By hitting E20 
    • Carbon monoxide emissions were 50% lower in two-wheelers and 30% lower in four-wheelers compared to petrol.
    • Hydrocarbons were lower by 20%.

What are the challenges with FFV?

  • Fuel Efficiency: E20 blending will result in drop in fuel efficiency by nearly 6-7% in 4 wheelers designed for E0 and calibrated to E10.
  • Requirement of Automobile Parts: Auto parts that come in contact with higher ethanol content have to be replaced with a compatible product to avoid corrosion.
  • Increased Cost: Because of changes required for vehicle components, higher blending of ethanol increases manufacturing costs of vehicles. Nevertheless, Automotive companies say that they are ready to move with E20 by 2025.
