Ethanol as an alternate fuel:


Context:

Government has been promoting use of ethanol as a blend stock with main automotive fuel like petrol in line with the National Policy on Biofuels (NBP) -2018 under the Ethanol Blended Petrol (EBP) Programme.

  • This policy envisages an indicative target of blending 20% ethanol in petrol by 2030.

Efforts by the Government in this regard:

  1. Government has allowed production of ethanol from sugarcane and food grain based raw-materials.
  2. The Government has fixed the ex-mill price of ethanol from sugarcane based raw-materials.
  3. Remunerative prices of ethanol produced from different feedstock has been fixed.
  4. The government has notified interest subvention schemes for setting up of molasses and grain based new distilleries or expansion of existing distilleries.

Ethanol:

  • Ethanol can be produced from sugarcane, maize, wheat, etc which are having high starch content.
  • In India, ethanol is mainly produced from sugarcane molasses by fermentation process.
  • Ethanol can be mixed with gasoline to form different blends.
  • As the ethanol molecule contains oxygen, it allows the engine to more completely combust the fuel, resulting in fewer emissions and thereby reducing the occurrence of environmental pollution.
  • Since ethanol is produced from plants that harness the power of the sun, ethanol is also considered as renewable fuel.
