6 FAQs about [Storage tank filling pressure]

Why is high pressure filling a hydrogen storage tank dangerous?

During the high pressure filling, the temperature in the hydrogen storage tank (HST) may rise rapidly due to the hydrogen compression. The high temperature may lead to safety problem. Thus, for fast and safely refueling the hydrogen, several key factors need to be considered.

Does hydrogen pressure affect the safety of a storage tank?

The temperature rises within tank due to the increase of hydrogen pressure during the filling process, which may seriously affect the safety of the storage tank. Filling experiments and simulations were conducted under various filling scenarios to study the thermal characteristics of the system.

What factors influence the filling process of hydrogen tank?

The effects of filling parameters on temperature rise According to theoretical analysis, the factors influencing filling process of hydrogen tank include: mass filling rate, initial temperature, initial pressure, filling pressure, and inlet temperature.

Do filling parameters affect tank wall peak temperature?

The influence of filling parameters on the tank wall peak temperature is assessed. The tank materials heat diffusivity is the critical parameter for fast fillings. Abstract Fast fillings of hydrogen vehicles require proper control of the temperature to ensure the integrity of the storage tanks.
