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.

Provided is a heat generating arrangement and a method for generation of heat to be used in a heat consumer. The heat generating arrangement uses combustion of aluminium and hydrogen to raise the temperature of superheated steam inside the heat generating arrangement. The heat in the superheated steam can thereafter be used in a heat consumer, such as a heat exchanger.
