Abstract
Hydrogen energy, as a clean and efficient energy source, has been widely applied in the transportation sector. To enhance the efficiency of hydrogen usage, compressed gas storage and transport methods are commonly employed, and the safety of hydrogen storage cylinders has become a focal point of numerous scholars. However, current research predominantly focuses on the temperature rise during hydrogen filling, with less attention given to the temperature drop during hydrogen emptying. Therefore, this paper aims to conduct a comprehensive study on the hydrogen filling and emptying processes in vehicle-mounted hydrogen storage cylinders, exploring the impacts of various factors (filling/emptying rate, gas source temperature, environmental temperature, residual pressure in the cylinder) on the temperature rise and drop of the cylinders. Additionally, a method for predicting temperature will be proposed to guide the practical application of hydrogen filling and emptying processes.
期刊介绍:
The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc.
The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
