Green Ammonia – UPSC Prelims

Green Ammonia:
  • Ammonia is a chemical which is used mainly in the manufacture of nitrogenous fertilizers, like urea and ammonium nitrate, but can be put to other uses too, such as to run engines.
  • Green ammonia production is where the process of making ammonia is 100% renewable and carbon-free.
  • One way of making green ammonia is by using hydrogen from water electrolysis and nitrogen separated from the air. These are then fed into the Haber process (also known as Haber-Bosch), all powered by sustainable electricity.
  • In the Haber process, hydrogen and nitrogen are reacted together at high temperatures and pressures to produce ammonia, NH3.
  • Green ammonia is intended to be used in the production of carbon-neutral fertiliser products, decarbonising the food value chain, and also has potential as a future climate-neutral shipping fuel.
  • Green ammonia production makes use of renewable energy sources such as hydro-electric, solar power or wind turbines.
  • Green ammonia is crucial to tackle the existential challenges of producing enough food to feed a growing global population and generating CO2-free energy.
