Fatigue Failure Analysis. The design life of the type IV hydrogen storage vessel is a crucial factor to consider when evaluating the fatigue performance of the four different BOSS structure models using two metal materials. This is estimated to be between 30 years, with an expected fatigue cycle life of 30,000 cycles.
However, the complex working environment of hydrogen-thermo-mechanism presents challenge to the failure analysis and predictive model establishment of the composite hydrogen storage tanks. The crucial parameters or indicators for tank''s failure analysis include burst pressure, damage state and fatigue lifetime, etc.

Low-temperature storage: Low-temperature hydrogen storage involves storing hydrogen as a liquid at cryogenic temperatures (− 253 C or − 423 F). The advantage of this approach is that liquid hydrogen has a much higher energy density than compressed hydrogen gas, which means that a larger amount of hydrogen can be …
