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