Why Ammonia

Green Ammonia is essential to drive the energy transition to ‘net zero’ carbon for sectors that cannot easily be electrified.

Ammonia (NH3) is currently the second most widely produced chemical in the world, with around 200 million metric tons being produced each year from fossil fuels.  Ammonia has a variety of different uses, from fertilisers to industrial chemicals, all of which result in significant CO2 emissions when the hydrogen (H2) is supplied from a fossil fuel feedstock.

Producing green hydrogen from renewable electricity and water removes the upstream CO2 emissions enabling all existing downstream uses to be decarbonised, and opens up new use cases for green ammonia. In contrast with hydrogen, ammonia is easier to transport and store and has an existing global logistics and supply network. Given the wide scale use of ammonia today, its safety and handling protocols are well understood.

Ammonia has many direct uses, and is also a vector to store and transport hydrogen with conversion back into hydrogen, at the point it is needed.
