The production, storage and transportation of ammonia are industrially standardized. However, the ammonia synthesis process on the exporter side is even more energy-intensive than hydrogen liquefaction. The ammonia cracking process on the importer side consumes additional energy equivalent to ~20% LHV of hydrogen.

Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.
