Green Hydrogen

  • It is produced by splitting water into hydrogen and oxygen using an electrolyser powered by renewable energy sources such as wind and solar.
  • The fuel can be a game-changer for the energy security of India, which imports 85% of its oil and 53% of gas requirements.
  • To promote clean fuels, India is considering making it mandatory for fertilizer plant and oil refineries to purchase green hydrogen.

Other Forms of Hydrogen

  • Brown hydrogen:
    • It is produced using coal where the emissions are released to the air.
  • Grey hydrogen:
    • It is produced from natural gas where the associated emissions are released to the air.
  • Blue hydrogen:
    • It is produced from natural gas, where the emissions are captured using carbon capture and storage.
