Fuel cell systems are a potential next-generation energy system. In this context, the increased demand for hydrogen in the coming years means that traditional systems and materials previously used for hydrogen transport and storage will need to be adapted to allow delivering larger amounts of hydrogen efficiently. Furthermore, due to the low energy density of hydrogen, pipes and vessels for transportation and storage will have to be designed to sustain high hydrogen pressures of up to 70 MPa. The best economical solution would be the use of medium- and high-strength ferritic steels in order to reduce the thickness of pipes and vessels and hence the material costs. Vessels and pipes used to store and transport hydrogen must be able to provide a safe service during long periods of time in direct contact with gaseous hydrogen under high internal pressure, being so essential to ensure good resistance to hydrogen embrittlement.
