To answer Swoop223 question. Now at the beginning there will be some fossil fuel involvement because of how Ammonia need's to be transported from the main filling point to the customer. in fact, in the United Stated there are already 2000 miles of ammonia pipelines along with a substantial infrastructure for ammonia manufacture and distribution.
Ammonia is regularly used in refrigeration and heat pumps so its highly likely people are passing near safely stored ammonia regularly in their everyday lives at sites such as hospitals, supermarkets amongst many others
A study by the Royal Society highlight substantial savings using Ammonia in Rail, Shipping and Heavy Road Transport... in fact nearly 80% reduction to that of Hydrogen gas and a third of the costs of liquefied Hydrogen.
Ammonia could absolutely be zero carbon. you can make green Hydrogen (either with green electricity or carbon capture & storage) and green electricity you can make green ammonia. You just need a lot of green energy!
The truck itself is zero emission but the process of getting the fuel to the customer might have some emissions attached, this could also be added to battery power as the electric use could come from fossil fuel powerplants. As technologies progress then the process will use less fossil fuels and in some cases like ports that have a green ammonia plant near by for produce liquid ammonia for ships and the ammonia is piped into the port. It would be 100% completely zero emission.
As the truck is completely modular it adds benefits to companies that rent forklifts instead of purchasing them. More and More companies will rent rather than purchase, If anything what is happening at the moment will show companies that rental is better than purchase, If a company has rented a forklift with an open return option they can off hire the truck to re hire it when its needed. If a company has Purchased a truck or leases a truck they still have to pay for the truck even though them might not even be working. As the modular can easily be exchanged in case of a fault arising or for servicing or exchanged to extend the trucks life the TCO will be much lower that that of a Diesel truck.
