What is Ethanol Blending?

  • The ethanol blending is process of mixing petrol with ethanol.
  • The mixture is called as Ethanol Fuel / Gasohol which is considered as a quasirenewable energy.

Uses

 India’s plans

  • India should increase the use of biofuels
  • Government intends to raise ethanol blending in petrol to 20% by 2030 from the current 2-3%
  • BUT NOT A GOOD IDEA

Water usage

  • Water footprint, that is water required to produce a litre of ethanol, includes rainwater at the root zone used by ethanol-producing plants such as sugarcane, and surface, groundwater, and fresh water required to wash away pollutants

Land resources

  • Land requirement is likely to put a stress on other crops and has the potential to increase food prices

Biofuel policy

  • India’s biofuel policy stipulates that fuel requirements must not compete with food requirements and that only surplus food crops should be used for fuel production
  • Producing ethanol from crop residue will be a good alternative but the annual capacity of required bio-refineries is stipulated to be 300-400 million litres, which is still not enough to meet the 5% petrol-ethanol blending requirement

WAY FORWARD

  • Increasing petrol-ethanol blending does not seem viable in the current scenario
  • Concerted efforts need to be made to either increase sugarcane yield and decrease water usage through better irrigation practices, or increase the ethanol production capacity of bio-refineries
  • Trying to increase blending without these efforts can encroach upon land and water available for food production
