In this article,some technologies for hydrogen production with low environmental load are discussed.Producing hydrogen by water electrolysis with SPE is a mature technology and will be one of the main ways of hydrogen production.Bio-hydrogen production and photochemical water splitting,only consuming solar energy,have a wide prospect of application.Producing hydrogen from biomass,which is clean and energy-saving,is worth to be popularized.Developing integrated hydrogen production system with low environment load is a tendency in hydrogen production.
