So it's basically just a way to store hydrogen as ammonia. The Haber-Bosch process isn't very energy efficient, though.

- elcritch 6y agoAre 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...
- toomuchtodo 6y agoDoesn’t have to be efficient with renewables that otherwise would’ve been curtailed (throwing away that clean energy). Still more energy dense than batteries (for marine vessel use).
- csours 6y agoI agree, but I'm curious to see how it will shake out in real life.
- ncmncm 6y agoHaber-Bosch is the low-tech method you use when you only have heat. With high-grade electric power, you can use efficient catalysis. The Chinese are doing a great deal of good work developing catalysts.
