One of the main challenges in hydrogen gas storage is its low energy density under ambient conditions. The existing system uses a 6061-T6 Aluminium pressure vessel; its yield stress is assumed to be 280 MPa . If you replace this vessel with a filamentwound E-glass/epoxy vessel of the same size, consider a safety factor of 3 . What is the estimated allowable internal pressure for the vessel? Based on your analysis, compare the two vessels. The pressure vessel dimensions and details are shown in Figure 2. [12] rigure
