I always thought of technologies like these as potential solutions to the grid-storage problem: excess solar and wind energy can be put into electrolysis, and then the metals can be burned to provide base load power — while keeping lithium for portable use-cases

Melting iron oxides needs very high temperatures which makes everything more complex.
