Stars cant use Fe's chemical energy because they're too hot and the entropy of not being bound to O2 is too high. (And Fe is a trace element). No one is talking about using Fe as fuel in a nuclear reactor, or (even though the article muddles this) as a primary source of chemical energy. Its a battery. A heavy, big battery.
