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	Features
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
