Pure Green Hydrogen Plant

Subject: Environment

Context- India’s first pure green hydrogen plant commissioned in Jorhat.

Concept-

  • Oil India Limited (OIL) has taken the first significant step towards Green Hydrogen Economy in India with the commissioning of India’s First 99.999% pure Green Hydrogen pilot plant, with an installed capacity of 10 kg per day at its Jorhat Pump Station in Assam today.
  • The plant produces Green Hydrogen from the electricity generated by the existing 500kW Solar plant using a 100 kW Anion Exchange Membrane (AEM) Electrolyser array.
  • The use of AEM technology is being used for the first time in India.
  • This plant is expected to increase its production of green hydrogen from 10 kg per day to 30 kg per day in future.
  • The company has initiated a detailed study in collaboration with IIT Guwahati on blending of Green Hydrogen with Natural Gas and its effect on the existing infrastructure of OIL.

Hydrogen:

  • Hydrogen is one of the most abundant elements on earth for a cleaner alternative fuel option.
  • Type of hydrogen depend up on the process of its formation:
  1. Green Hydrogen:
    • Green hydrogen is produced by electrolysis of water using renewable energy (like Solar, Wind) and has a lower carbon footprint.
    • Electricity splits water into hydrogen and oxygen.
    • By Products : Water, Water Vapor.
    • Green hydrogen can drive India’s transition to clean energy, combat climate change.
    • India has a favourable geographic location and abundance of sunlight and wind for the production of green hydrogen.
    • Current Status Worldwide:
      • Less than 1% of hydrogen produced is green hydrogen.
      • Manufacturing and deployment of electrolysers will have to increase at an unprecedented rate by 2050 from the current capacity of 0.3 gigawatts to almost 5,000 gigawatts.
  1. Brown hydrogen:
    • Brown hydrogen is produced using coal where the emissions are released to the air.
  1. Grey Hydrogen:
    • Grey hydrogen is produced from natural gas where the associated emissions are released to the air.
  1. Blue Hydrogen:
    • Blue hydrogen is produced from natural gas, where the emissions are captured using carbon capture and storage.
