an optimized control method for a high utilization ratio and fast filling speed in hydrogen refueling stations
International Journal of Hydrogen Energy, 2010Co-Authors: Jinyang Zheng, Jian Yang, Ping Tang, Lei Zhao, Maradee KernAbstract:A well-designed control system with a high utilization ratio of hydrogen and a fast filling speed are two critical objectives to ensure the reduction of cost and time required in the refueling process. In this paper, the popular three-stage refueling process is modeled with the aim to address both objectives. Using the Real Gas Law of hydrogen, the utilization ratio of hydrogen filling is analyzed and the filling flowrate and time of each stage are evaluated. A multi-objective iterative optimization model is established and an optimization algorithm for the filling process is proposed to achieve both fast refueling and high utilization. Numerical results can be applied to the optimization of an actual hydrogen filling process. Besides, the tests show that an optimized control method can significantly improve the utilization ratio and allow refueling in a widely acceptable time.

Optimization of Hydrogen Utilization Ratio in Hydrogen Filling Stations
Volume 1: Codes and Standards, 2008Co-Authors: Honggang Chen, Jinyang Zheng, Yanlei Liu, Pengfei Liu, Haiyan BieAbstract:High pressure hydrogen storage is widely used in hydrogen filling stations and fuel cell automobiles. Currently, single filling is the main method for hydrogen transfer from stationary storage tanks to cylinders of fuel cell automobiles. Along with the wide application of hydrogen the multistage filling will be adopted in hydrogen filling stations due to its high hydrogen utilization ratio. The hydrogen utilization ratio of single or multistage filling can be determined by various parameters such as the pressure and volume of the stationary tanks and cylinders of fuel cell automobiles. In this research, the utilization ratios of hydrogen in different filling methods are analyzed using the algorithm established in this article based on the Real Gas Law of hydrogen and the corresponding hydrogen utilization ratios are obtained. The results show that it can be significantly improved using multistage filling method and reaches a maximum as the ratio of the volume of higher-pressure stationary tank to the lower one is 0.5.Copyright © 2008 by ASME
