Distributed Multi-Objectives Power System Based on Renewable Energy(2)

In distributed multi objective power systems based on renewable energy, hydrogen will be used as energy carrier. Two schemes for hydrogen production were suggested and the sub systems were structured and introduced. In these schemes, hydrogen is produced either from water by direct photoelectrochemical splitting methods based on solar energy, or from biomass and water by thermochemical splitting method based on waste heat in industries or solar conecntrating thermal energy. Hydrogen production equipment for both methods was established in our laboratory, and systematical studies on the gasification efficiency, chemical reaction mechanism and dynamics have being completed. Hydrogen production sub systems can be combined with high temperature fuel cells, micro gas turbine or integrate all the technologies into a hybrid system. The hybrid system complemented with cooling heating humidity control sub system will produce hydrogen, electricity, heat, cool and work. The theories and technologies for high efficiency, low cost and pllution free hydrogen production schemes based on renewable energy were discussed and analyzed. Some new experimental results about hydrogen production are reported.
