The Haber-Bosch process is a reversible reaction, which enables ammonia to act as a storage and transportation vector for hydrogen. By coupling the production process to renewable energy, there are no carbon emissions associated with the production of green ammonia. This opens up new direct and indirect markets, as it offers ways to decarbonise a range of sectors.
Using green ammonia for the supply of hydrogen has clear benefits. As the second most widely produced chemical in the world, 200 million tons of ammonia are produced each year. It is easy to transport and store with an existing global logistics and supply network. It doesn’t require high pressure storage like hydrogen and when ammonia is cracked to produce hydrogen no harmful pollutants are emitted.
