Diaphragm tanks are commonly used on the discharge manifold to provide water storage for the system in very low flow situations. It decreases the running time of the booster pumps, thereby making the system more energy effective. Since the diaphragm is flexible, it is able to adjust to sudden pressure changes, thus counteracting water hammering.

The tank roof is an extremely complex part of the LNG storage tank structure [ 11 ]. The tank roof of the full-scale LNG storage tank is mainly composed of two parts: the vault and the suspended ceiling. It is assumed that the outer tank wall temperature is equal to the ambient temperature (T_ {E}), and the inner tank wall

High-pressure gaseous hydrogen storage, liquid hydrogen storage, solid hydrogen storage [16], and organic liquid hydrogen storage are some of the current hydrogen storage technology options. Compressed gas hydrogen storage is the most advanced technique currently used in the vehicle sector [17].

Diaphragm tanks are a common type of pressurized tanks in which the diaphragm is used to separate the fuel part from the high-pressure part, compress the fuel in the tank, and reduce free space to avoid liquid fuel sloshing. The main purpose of the application of the diaphragm tanks is to ensure the continuous flow of pure fuel without
