A Feasible and Green Approach for Developing Hydro gen Energy
2019
Wenting Zhang, Yifeng Liu and Yingmei Xu
Hydrogen is recognized as the green energy with the greatest potential for future development, but currently, China’s hydrogen production is highly dependent on raw fossil materials, which conflicts with the original intention of developing hydrogen energy. As the abandoned hydropower problem in Southwestern China is serious. The current strategy can be focused using surplus hydropower to produce hydrogen in a green way. In this study, the technical cost and advantage of hydrogen produced using surplus hydropower using the levelized cost of energy model was analyzed. The results show that cheap surplus hydropower will considerably reduce the cost of hydrogen produced using electrolyzing water, and the cost is comparable to that of coal gasification hydrogen production. The hydropower to be abandoned by Southwestern China annually can drive the hydrogen production with 1.2 million tons per year, providing a technically and economically feasible approach to developing hydrogen energy.
