Method and Apparatus for Hydrogen Production

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a process and system for producing hydrogen from water using a cyclic reaction involving zinc. In the process, zinc particles in an alkaline solution are oxidized to zinc oxide, releasing hydrogen. The produced zinc oxide is then electrochemically reduced back to zinc, releasing oxygen, and recycled to repeat the cycle.

Patent Abstract

The invention relates to a method for hydrogen generation from water, in which a pumpable suspension of zinc particles in alkaline solution is supplied to an oxidation unit, in which zinc is oxidized electrochemically or thermally to zinc oxide in the oxidation unit (3) with release of hydrogen, the suspension leaving the oxidation unit (3) is supplied to a reduction unit (4) and in the reduction unit (4) zinc oxides formed during oxidation are reduced electrochemically to zinc with release of oxygen, whereupon the suspension leaving the reduction unit (4) is supplied again to the at least one oxidation unit (3).
