There are fuel cell powered drones out there. Size hasn't been an issue for a long time.
Do you know what the technology is for the pressurized H2 at these sizes? Its been my understanding that larger vehicles scale better (ie: thicker walls and bigger containers) to better deal with the H2 volume issue.
Bigger vehicles can take advantage of exotic / expensive processes like liquified H2 or 700-bar pressures or whatnot. I don't think that's been miniaturized to drone or forklift sizes though.
They're still using pressurized gas tanks. Apparently, not even a drone is not too small for such things.
What an edifying thread, thank you both for knowing stuff about things
