In a significant move for the progress of the National Green Hydrogen Mission, the government has notified the Green Hydrogen Standard for India.

About Green Hydrogen Standard:


  • The Ministry of New & Renewable Energy has decided to define Green Hydrogen as having a well-to-gate emission (i.e., including water treatment, electrolysis, gas purification, drying and compression of hydrogen) of not more than 2 kg CO2 equivalent / kg H2.
  • The Bureau of Energy Efficiency (BEE), Ministry of Power shall be the Nodal Authority for accreditation of agencies for the monitoring, verification and certification for Green Hydrogen production projects.
  • The scope of the definition encompasses both electrolysis-based and biomass-based hydrogen production methods.


What is Green Hydrogen?

  • Hydrogen gas (produced using industrial methods like electrolysis) can be used as a fuel and it does not release greenhouse gas (GHG) emissions such as carbon dioxide (CO2) when it is burned. Hence, a potential clean alternative to fossil fuels.
  • Green hydrogen is the name given to hydrogen gas that has been produced using renewable energy, such as wind or solar power, which create no GHG emissions.
  • Globally, most of the hydrogen produced today is used in the refining and industrial sectors - to make ammonia for the fertiliser industry, in the steel industry.
  • In a fuel cell (device that converts the energy of a chemical into electricity), hydrogen gas reacts with oxygen to produce electricity and water vapour.


Q1) What is Electrolysis?

Electrolysis is a chemical process that involves using an electric current to drive a non-spontaneous chemical reaction. It's a fundamental concept in chemistry and has practical applications in various industries and technologies.
