The purpose of this research is to establish a hydrogen production/reduction cycle using solar energy. This cycle is based on the zinc oxide redox system. Sunlight is focused by a Fresnel lens and used as a heat source. When zinc oxide and carbon are heated in a reaction tube, the zinc oxide is reduced to form zinc. Zinc and water react to produce hydrogen. This time, we conducted the experiment under atmospheric pressure rather than under a vacuum atmosphere. As a result, the amount of hydrogen obtained was 347mL when using an electric furnace, and 107mL when using sunlight.
