About Green Ammonia:

  • It is produced 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) which is 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 production is where the process of making ammonia is 100% renewable and carbon-free.
  • It can be used in
    • Fuel for engines such as locomotives and shipping, replacing diesel and marine fuel oil
    • Fuel source for electricity power generation
    • Building block to make fertilisers for use in agriculture
    • Feedstock for industrial and manufacturing applications ranging from water purification through to pharmaceuticals


Key facts about Ammonia

  • It is a colorless highly irritating gas with a sharp suffocating odor.
  • It dissolves easily in water to form ammonium hydroxide solution which can cause irritation and burns.
  • Ammonia gas is easily compressed and forms a clear, colorless liquid under pressure.
  • It is usually shipped as a compressed liquid in steel cylinders.
  • Ammonia is not highly flammable, but containers of ammonia may explode when exposed to high heat.
