SYSTEM AND METHOD FOR MAKING GREEN HYDROGEN

Resumen de: AU2025213224A1

A system and method of making hydrogen from water. A reaction vessel is provided with an outer shell, a central shaft, and concentric inner tubes separated by annular spaces. Water is delivered to the annular spaces by a water pump through an inlet defined in the reaction vessel. The water courses along a tortuous flow path. That path begins at an inner annular space around a central shaft. It ends at an outer annular space. The water emerges from the reaction vessel through an outlet associated with a manifold. A vibratory stimulus is applied to the reaction vessel and water. Water molecules are dissociated into hydrogen molecules and oxygen atoms. These reaction products are delivered through the manifold along an effluent flow path to a receiving pressure vessel before deployment to a sub-assembly for harnessing clean energy.
