To solving the problems of conventional steam reforming of methane process, a novel two-step steam reforming of methane thermochemical cycle is proposed for pure hydrogen production. The whole cyclic process is divided into two steps. The first step is methane partial oxidation with lattice oxygen in metal oxide to form syngas and reduced metal oxide. The second step is metal oxide and hydrogen production from water splitting with reduced metal oxide, and metal oxide from this step is recycled to the first step and cyclic used. Principle and thermodynamics of this new cycle was introduced, different reaction systems was discussed. Coupled with solar energy, it is prospective to get a clean and economical way for hydrogen production.
