Hydrogen has the potential to decarbonise a wide range of heavy industries including energy, chemicals, steel, and cement, which means demand is going to be huge. In its Net Zero emissions scenario the IEA expects demand to increase fivefold from 2020 to 2050. However, there are a few important limitations to overcome for hydrogen to become competitive.
The first challenge is to produce sufficient supply of renewable green hydrogen; the next is to be able to store it in large quantities; and then to establish the required infrastructure to trade and transport hydrogen. This is where ammonia comes into play. Consisting of one nitrogen and three hydrogen atoms, the ammonia molecule (NH3) has the potential to support the hydrogen fuel economy in all three domains.
