Hydrogen production by water dissociation in the presence of SnO using the SnO2/SnO couple in a series of thermochemical reactions

摘要

The invention relates to a method for preparing hydrogen that comprises a hydrolysisstep (C) of solid SnO for producing hydrogen, in which the hydrogen thus producedis stored, recovered and/or upgraded, and in which the solid SnO used is obtainedby the following steps: (A) thermal reduction of SnO
