National Hydrogen Energy Mission (NHEM)

About National Hydrogen Energy Mission, 2021-22

  • The Union Budget for 2021-22 has announced a National Hydrogen Energy Mission (NHEM) to draw up a road map for using hydrogen as an energy source. This initiative can transform transportation.
  • NHM initiative will capitalise on one of the most abundant elements on earth (Hydrogen) for a cleaner alternative fuel option.

About NHEM:

  • Focus on the generation of hydrogen from green power resources.
  • To link India’s growing renewable capacity with the hydrogen economy.
  • The usage of hydrogen will not only help India in achieving its emission goals under the Paris Agreement, but will also reduce import dependency on fossil fuels.
  • India's ambitious goal of 175 GW by 2022 got an impetus in the 2021-22 budget which allocated Rs. 1500 crore for renewable energy development and NHEM.

About Hydrogen fuel:

  • Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water.
  • Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind.
  • These qualities make it an attractive fuel option for transportation and electricity generation applications. It can be used in cars, in houses, for portable power, and in many more applications.
  • Hydrogen is an energy carrier that can be used to store, move, and deliver energy produced from other sources.
  • Today, hydrogen fuel can be produced through several methods. The most common methods today are natural gas reforming (a thermal process), and electrolysis. Other methods include solar-driven and biological processes.

Type of Hydrogen: Grey Hydrogen, Blue Hydrogen, Green Hydrogen

Types of Hydrogen


1. Grey Hydrogen

  • It constitutes India’s bulk Production.
  • Extracted from hydrocarbons (fossil fuels, natural gas).
  • It’s by product is CO2

2. Blue Hydrogen

  • Sourced from fossil fuels.
  • It’s by product is CO, CO2
  • By products are Captured and Stored, so better than gey hydrogen.

3. Green Hydrogen

  • Generated from renewable energy (like Solar, Wind).
  • Electricity splits water into hydrogen and oxygen.
  • By Products : Water, Water Vapor
