1. Your first "question" isn't even a question. Even trying to wade through a limited grasp of the English language, I cannot determine what you are actually trying to ask.

2. I think Hydrogen has the potential to power more equipment in the future. The issue isn't so much the fuel system itself, but the infrastructure to support said system. It is same reason purely electric automobiles have not taken off like they should. I do however, believe Hydrogen stands a much better chance than Ammonia does. You should use Hydrogen as an example, it has been in the material handling market for a long time, and still has yet to gain a firm foothold in anything but large warehouse fleets.
