The zinc-zinc oxide cycle is a two-step thermochemical cycle based on zinc and zinc oxide for hydrogen production, with a typical efficiency around 40 percent. The cycle uses a redox process to split water in two distinct steps: first the thermal dissociation of zinc oxide into zinc and oxygen, and then the hydrolysis of that zinc with water to produce hydrogen and regenerate zinc oxide, which can then be dissociated again to repeat the cycle.
