Iron and other metals can dissolve enormous emounts of hydrogen - and yeah despite ALL the crap about "The Hydrogen Economy" - hydrogen leaks INTO all metals and it leaks THROUGH them and OUT of them.... Hydrogen is a tiny atom and it is a mon-atomic element - meaning ONE atom gets around by it's self, so it CAN go through solid steel....
