Actually, that works in favour of this method here, provided certain conditions are met. Aluminium takes a big juicy bunch of electricity. Its very energy intensive. But, if we can extract a good portion of that aluminium energy as hydrogen gas, then aluminium acts as a highly energy dense battery. It can then be effectively used for grid scale energy storage.
