This invention is directed toward a process, method and device for the production and/or derivation of hydrogen utilizing microwave energy through use of a microwave susceptor that absorbs/assimilates microwave energy and converts it to radiant/heat energy which is imparted to iron and alters its physical characteristics such that water in contact with the iron will have one of its physical characteristics, preferably temperature, altered, and result in a reaction of the to produce/derive hydrogen. Invention also includes a progressive change to water prior to it achieving a reactive threshold with the iron element, and the progressive preparation and/or pretreatment of water, via exposure or contact of water with other materials with high thermal conductivities in lieu of iron through use of a microwave susceptor.
