It's actually this news that made me curious about the potential for hydrogen to act as a battery for solar projects where pumped hydro doesn't make sense. I've read that the water output of hydrogen energy generation is non-recyclable, if that's solvable we could have excess solar in arid places along with a fully-contained hydrogen electrolysis and power generator combination acting as a battery
