Amazon thinks hydrogen can be a more sustainable fuel for vehicles at its warehouses, but it’ll have to clean up hydrogen production first.

    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

      The drones generally don’t use compressed hydrogen (at least the ones I’ve seen). It’s too dangerous. Instead they use a pellet based storage system. You can liberate hydrogen from it, but it’s rate limited. It will burn, but it can’t launch like a flaming rocket.

      The downside is the pellet systems aren’t as simple as just refilling the tank.
