India’s first pure green hydrogen plant commissioned

Part of: Prelims and GS III – Economy

Context: 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.

  • 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.
  • Expected to increase its production of green hydrogen from 10 kg per day to 30 kg per day in future.

Green Hydrogen

Green hydrogen is hydrogen gas produced through electrolysis of water — an energy intensive process for splitting water into hydrogen and oxygen— using renewable power to achieve this.

Green hydrogen has specific advantages –

  • Environment Friendly: Green Hydrogen as energy source is seen as the next big thing as its usage would lead to zero emissions
  • Potential to Decarbonise various sectors: It is a clean burning molecule, which can decarbonise a range of sectors including iron and steel, chemicals, and transportation.
  • Efficient utilization of Renewable Energy: Renewable energy that cannot be stored or used by the grid can be channelled to produce hydrogen.
  • Reduced Dependence on Rare Minerals: Green Hydrogen also holds the key to clean electric mobility that doesn’t depend on rare minerals. Green Hydrogen helps achieve long-term vision of reduced dependency on minerals and rare-earth element-based battery as energy storage.
  • Helps Achieve Paris Goal: Green hydrogen energy is vital for India to meet its Nationally Determined Contributions and ensure regional and national energy security, access and availability
  • Energy Security: Green energy helps reduce import dependency on fossil fuels

Challenges with regard to Hydrogen Fuel

  • Fuelling Infrastructure: A big barrier to the adoption of hydrogen fuel cell vehicles has been a lack of fuelling station infrastructure — fuel cell cars refuel in a similar way to conventional cars, but can’t use the same station (only 500 in the world & that too in Europe, Japan, South Korea)
  • Safety is seen as a concern: Hydrogen is pressurised and stored in a cryogenic tank, from there it is fed to a lower-pressure cell and put through an electro-chemical reaction to generate electricity.
  • Scaling up the technology and achieving critical mass remains the big challenge. More vehicles on the road and more supporting infrastructure can lower costs.
