| Summary: | Storage and transportation is one the complicated problems in the direction of the Hydrogen industrial application. The recent paper examines the use of relatively light and low cost two types of composed materials to transport the Hydrogen. The investigation is carried out numerically by finite element technique. The vessel is modeled and simulated using ANSYS software. The selected composites are Glass/Epoxy and Graphite/Epoxy. The initial temperature of cryogenic is -70oC. The analysis is conducted under the assumption of external temperature variation from 22oC to 400oC. It is found, for both selected composites, that the materials are capable to maintain the storage conditions safely and stable up to 360oC external surface temperature.
