How do I refill hydrogen bottle?

[AmIEgged(]

I'm pretty sure I used to be able to do this. I would think that I would put it in the oxygen tank because thats how I refill my oxygen bottles but it's grayed out meaning it doesn't let me put it in the tank but it only lets me put it in the oxygen generator which does nothing...
help pls

Yes, you put the hydrogen bottle into the Oxy Gen. But they will not fit through small conveyors.

Also, make sure there is room in the Ox Gen's inventory. If it is absolutely full of ice they won't fit. Turn off "Use Conveyors" and remove about 2K kg of Ice to make room for the bottles.
