Before air separation and liquid nitrogen became prevalent, ammonia cracking was used to produce small amounts of nitrogen. However, as the potential of international hydrogen supply chains emerges, small-scale ammonia cracking will be required to convert ammonia into hydrogen at the point of use.
Unlike pure hydrogen, gaseous or liquid, liquid ammonia is easy to store and transport due to its high energy density. It can also be conveniently cracked back to hydrogen on demand near the point of consumption.
On-demand, decentralised hydrogen generation
