Are there more direct methods? It seems like ammonia would be much easier to transport than hydrogen, but at the cost of another loss of efficiency is a big hit

Are there more direct methods? It seems like ammonia would be much easier to transport than hydrogen, but at the cost of another loss of efficiency is a big hit. Though it might be cheaper for cargo ship operators who have a lot of capital investment. Looks like ammonia is mostly produced from hydrogen stripped from natural gas: https://cen.acs.org/environment/green-chemistry/Industrial-ammonia-production-emits-CO2/97/i24 https://cen.acs.org/environment/green-chemistry/Industrial-a...
