A viable energy system is a supporting pillar of strong economic growth but for sustainable growth, this energy needs to be environment friendly.
India is hosting a 2-day summit on green hydrogen initiatives involving the BRICS nations. This summit will provide a platform for all nations to share the best practices related to green hydrogen and discuss methods to scale their models.
The Union Minister of New and Renewable Energy, while addressing the Hydrogen Roundtable on “Hydrogen Economy: New Delhi Dialogue – 2021” said, “We are working on a pilot project on Blue Hydrogen, Hydrogen CNG (H-CNG) and Green Hydrogen. Through technological advancements, we are blending hydrogen with compressed natural gas for use as a transportation fuel as well as an industrial input to refineries. 50 buses in Delhi are plying on blended hydrogen in Compressed Natural Gas on a pilot basis. We plan to scale it up in the coming months across the major cities of India.”
The Government of India announced the National Hydrogen Mission in the Union Budget 2021 for making a hydrogen roadmap for the country.
What is green hydrogen and how is it different from brown hydrogen?
We have around 6 million metric tonnes of hydrogen production every year but this hydrogen is produced by steam reforming of methane which produces a lot of carbon dioxide, a greenhouse gas. The hydrogen produced by this process is called brown hydrogen.
Green hydrogen, on the other hand, is produced by using renewable resources and by the electrolysis of water.
Benefits of Green Hydrogen and the proposed mission
South Korea is operating Hydrogen Fuel Cell production units under its Hydrogen Economy Development and Safe Management of Hydrogen Act, 2020.
Japan has come out with the Basic Hydrogen Strategy which aims to set up an international supply chain of hydrogen.
Challenges in unlocking the potential of Green Hydrogen
A shift to green energy like green hydrogen is a step in the right direction and it would help in achieving the sustainable development goal 7 which states: “Ensure access to affordable, reliable, sustainable and modern energy for all.”
