Context

India aspires to emerge as the leader of green hydrogen by taking advantage of the current energy crisis across the globe.

  • Oil India Limited (OIL) has commissioned India’s first 99.99% pure green hydrogen plant in eastern Assam’s Jorhat.

What is Hydrogen?

  • Hydrogen is the lightest, simplest and most abundant member of the family of chemical elements in the universe.
  • It is colourless, odourless, tasteless, non-toxic and highly combustible gaseous substance.

What is Green hydrogen?

  • Green hydrogen is the one produced with no harmful greenhouse gas emissions.
  • It is made by using clean electricity from surplus renewable energy sources, such as solar or wind power, to electrolyse water.
  • Electrolysers use an electrochemical reaction to split water into its components of hydrogen and oxygen, emitting zero-carbon dioxide in the process.
  • Green hydrogen currently makes up a small percentage of the overall hydrogen, because production is expensive.

How much green hydrogen is India producing?

  • India has just begun to generate green hydrogen with the objective of raising non-fossil energy capacity to 500 gigawatts by 2030.
  • It was on April 20, 2022 that the public sector OIL, which is headquartered in eastern Assam’s Duliajan, set up India’s first 99.99% pure green hydrogen pilot plant.
  • Research and development efforts are on-going for a reduction in the cost of production, storage and the transportation of hydrogen.

Advantages 

  • Hydrogen can be used to produce electricity using fuel cells.
  • Hydrogen, thus, can act as an energy storage device and contribute to grid stability.
  • The oxygen, produced as a by-product (8 kg of oxygen is produced per 1 kg of hydrogen), can also be monetised by using it for industrial and medical applications or for enriching the environment.

Verifying, please be patient.
