Abstract
An electrolytic water hydrogen production and storage system by combined solar energy with power grid was designed for household application in this paper. Based on different climate conditions of Beijing, Yinchuan and Hami, the dynamic performance of this system was analyzed by the software of TRNSYS and GenOpt. The results indicate that the optimal tilt angles of PV modules for three cities of Beijing, Yinchuan and Hami are 36.56°, 37.81° and 41.87°, respectively. The total power generated from PV modules are 38329.2, 47169.8 and 50701.2 kWh/year, respectively. Based on the same hydrogen supply rate and hydrogen storage tank capacity, the annual hydrogen generation in the three cities is roughly the same, 13151.5 m3 in Beijing, 13124.1 m3 in Yinchuan, and 13144.7 m3 in Hami. Hami takes the least amount of electricity from the power grid, resulting in a highest hydrogen production benefit of 87.73%. Yinchuan is 85.57%, and Beijing has the lowest benefit of 66.58%.;
