Ammonia requires input Natural gas2 evidenceEstablished relation
Ammonia depends on Natural gas.
Mechanism
Haber-Bosch synthesis takes hydrogen from steam reforming of natural gas in most plants; gas is both feedstock and fuel. Coal gasification and electrolytic hydrogen are the alternative routes and supply a minority of output.
