Green Hydrogen

Subject – Environment

Context – Green hydrogen, a new ally for a zero-carbon future.

Concept –

  • Hydrogen is the most abundant element on the planet, but rarely in its pure form which is how we need it. It has an energy density almost three times that of diesel. This phenomenon makes it a rich source of energy, but the challenge is to compress or liquify the LH2 (liquid hydrogen); it needs to be kept at a stable minus 253° C (far below the temperature of minus 163° C at which Liquified Natural Gas (LNG) is stored; entailing its ‘prior to use exorbitant cost’.
  • Black hydrogen is produced by use of fossil fuel, whereas pink hydrogen is produced through electrolysis, but using energy from nuclear power sources. ‘Green hydrogen’, the emerging novel concept, is a zero-carbon fuel made by electrolysis using renewable power from wind and solar to split water into hydrogen and oxygen.
  • Presently, less than 0.1% or say ~75 million tons/year of hydrogen capable of generating ~284GW of power, is produced.
  • According to studies by the International Renewable Energy Agency (IREA), the production cost of this ‘green source of energy’ is expected to be around $1.5 per kilogram (for nations having perpetual sunshine and vast unused land), by the year 2030; by adopting various conservative measures.
  • India is the world’s fourth largest energy consuming country (behind China, the United States and the European Union), according to the IEA’s forecast, and will overtake the European Union to become the world’s third energy consumer by the year 2030.
  • India is also gradually unveiling its plans. The Indian Railways have announced the country’s first experiment of a hydrogen¬-fuel cell technology-based train by retrofitting an existing diesel engine; this will run under Northern Railway on the 89 km stretch between Sonepat and Jind.
