It doesnt make sense, because of the tremendous energy required to make metallic aluminum.
Why not just electrolyze the h2o directly, with nuclear, solar or hydo power, instead of the spending the excess energy to mine the bauxite transport
it, then refine it and alloy it with an increadibally expensive metal.
The gaseous h2 can be transported just like any other gas or stored in a metalic hydrate to be released on need.
Although the chemistry behind it is very interesting its not very practical in the long run.
Its a very Rube Goldbergian idea.
