Abstract:
Hydrogen energy storage and transportation is an indispensable part in the hydrogen energy industry chain. It is also one of the bottlenecks restricting the development of the hydrogen energy industry. Currently, the research and demonstration of hydrogen energy storage and transportation technologies are promoted in an accelerated way at home and abroad. Herein, the application status, key equipment, risk management and standards, bottleneck issues and development direction of four common hydrogen energy storage technologies were discussed through literature research, including the high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, organic liquid hydrogen storage and solid hydrogen storage. The development status, bottleneck issues and development trend of hydrogen energy transportation technologies, such as hydrogen tube trailer transportation, pipeline transportation, liquid hydrogen vehicle and ship transportation and solid hydrogen transportation, were reviewed. Moreover, the current mainstream methods of economic analysis and the development ideas for improving the economic efficiency of hydrogen energy storage and transportation technology in the future were summarized. At last, some suggestions were proposed for the future development of key technologies of hydrogen energy storage and transportation.
