There's a neat trick where you catch the end of an aluminum wire on fire (presumably using electric arc) and then plunge it into water and it yanks o2 off of the water making a whole lot of h2.
It leaves alumina sludge in the water which you need to take to an aluminum smelter to get it back to it's original state.
IIRC the round trip efficiency is quite abysmal because the aluminum smelting process is insane.

Yeah I briefly looked into it; and the running gig now is “gassing up” with continually refreshed electrolyte solution - until eventually the aluminum anode is dead and must be replaced. Which is as you mentioned the standard aluminum smelting process 😂
