Abstract:The aim of this work is to present a novel hybrid plant for the production of a mixture of methane and hydrogen from a steam reforming reactor whose heat duty is supplied by a molten salt stream heated up by an innovative concentrating solar power plant developed by ENEA. By this way, a hydrogen stream, mixed with natural gas, is produced from solar energy by a consolidated production method as the steam reforming process and by a widely tested and pre-commercial technology as molten salts parabolic mirrors solar plant. After the hydrogen production plant, the residual heat stored in the molten salt stream is used to produce electricity. Therefore, the plant proposed is co-generative (hydrogen + electricity).
