Hi--

Fuel cells powered by ammonia are already being marketed in Europe by Diverse Energy Ltd for telecom and small diesel back-up applications. http://diverse-energy.com/who.html

These appear to be PEM type hydrogen fuel cells where the hydrogen is stored in the form of ammonia (or propane or hydrogen), and then cracked to hydrogen and nitrogen and purified for feed to the PEM fuel cell.

It is not clear at this point how the company generates the ammonia (i.e. wind, solar, or grid), but likely it is purchased merchant ammonia for now.

Thanks for the link.

Sounds complex, but a liquid fuel is sure a lot more palatable than gaseous. It will be interesting to compare full TCO for hydrogen vs ammonia or propane.
