About:

  • The ‘green’ depends on how the electricity is generated to obtain the hydrogen, which does not emit greenhouse gas when burned.
  • Green hydrogen is produced through electrolysis using renewable sources of energy such as solar, wind or hydel power.

Steps in India

  • In Apr Oil India Limited (OIL) commissioned India’s first 99.99% pure green hydrogen plant in eastern Assam’s Jorhat.
  • India has just begun to generate green hydrogen with the objective of raising non-fossil energy capacity to 500 gigawatts by 2030.
  • The National Hydrogen Mission was launched on August 15, 2021, with a view to cutting down carbon emissions and increasing the use of renewable sources of energy.

Hydrogen can be ‘grey’ and ‘blue’ too.

  • Grey hydrogen is generated through fossil fuels such as coal and gas and currently accounts for 95% of the total production in South Asia.
  • Blue hydrogen, too, is produced using electricity generated by burning fossil fuels but with technologies to prevent the carbon released in the process from entering the atmosphere.
