A system is capable to safely generate a continuous controlled hydrogen flow. The passive auto sufficient hydrogen system is very valuable for example for emergency power back up, propulsion application, battery charging or powering portable devices. Also, a chemical process generates hydrogen using alkali metals, alkaline earth metals, hydrides of alkali metals or hydrides of alkaline earth metals to obtain primary by products from water. Then, the primary byproducts react with a metal reactant to obtain additional hydrogen.

A method of safely mixing a hydrocarbon with an oxidant is provided. The hydrocarbon and oxidant are saturated with a non-flammable liquid in pre-mix zones that are flooded with the non-flammable liquid and fluidly connected to a common mixing zone that is partially flooded with the non-flammable liquid. The saturated hydrocarbon and oxidant combine within the common mixing zone forming bubbles of a homogeneous gas mixture of hydrocarbon and oxidant, preferably in a ratio of hydrocarbon to oxidant that is outside of the flammability limit, that can exit the non-flammable liquid into a headspace where it can be retrieved for use in an oxidative reaction process such as oxidative dehydrogenation.
