    I wonder the energy cost of creating the powdered iron. And of converting iron oxide back to iron powder.

      AFAIK it is not the most efficient, but can be done with surplus electricity from wind farms for example.

      Current (pilot test scale) electrical iron reduction is a bit more efficient than commercial hydrogen electrolysis. It may have some as-yet-unknown barriers to commercialisation though.
