    Maybe if they have easy efficient way to recycle gallium, which they don't mention.

    Sodium hydroxide is very cheap chemical that can be used instead to get hydrogen with aluminium, and unlike gallium don't have to be recycled. Perhaps the whole "get hydrogen from aluminium scrap" thing does not make economical sense anyway.
