Techno-economic analysis on the performance of hydrogen adsorbents in the vacuum layer of cryogenic liquid storage tank
The increasing demands for cryogenic liquid fuels pose serious challenges to storage and transportation technology. Hydrogen leakage occurs in cryogenic liquid storage tanks since hydrogen molecules can slowly diffuse through microscopic pores, which greatly weakens the performance of vacuum insulation layer. Various materials with high adsorption capacity have been developed to inhibit this phenomenon while few research focuses on the working performance inside tanks, which leads to the excessive dosage of adsorbents. This work aims to analyze the adsorption performance and economic benefits of hydrogen adsorbents in liquid hydrogen (LH) and liquid natural gas (LNG) tank, respectively. The results indicate that silver molecular sieve (SMS) is a cost-effective adsorbent in the long-term cryogenic liquid storage. LNG tank needs more ambient temperature adsorbents to maintain a similar performance to LH tank. For a 250 m3 LH tank, the optimal mass by using SMS ranges from 700 g to 800 g while a dosage of 900–1000 g is the best for a 250 m3 LNG tank. The excessive use of hydrogen adsorbents can't effectively improve the performance of cryogenic liquid storage tanks. These research findings may help the future vacuum maintenance in cryogenic liquid storage tanks.
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.
