Abstract：Building a sustainable energy system is one of the most critical issues that today's society must address. A sustainable fuel is needed to replace current energy carrier in the new energy system. Hydrogen is an ideal secondary energy. Hydrogen production in large-scale using solar energy which can solve the problems of sustainability, environmental emissions, and energy security and become the focus of the international competition in the area of energy science and technology. It is also be set as an important research direction by many large international hydrogen program. The basic research of hydrogen production in mass scale using solar energy has being founded by NNSFC from 1998 and National Basic Research Program of China from 2003. The status and prospect of mass hydrogen production using solar energy were commented on firstly and a series newest progress of theories and experimental research achieved by the State Key Laboratory of Multiphase Flow in Power Engineering of Xi'an J...更多itong University in this area were reported.
