High Pressure Hydrogen Storage System Based on New Hybrid Concept

Abstract

On market, high pressure storage systems have a shape of cylinder with a high specific inner diameter and length. The state of the art structure is only a metal liner or assembled with composite material, like carbon, by wrapping. The liner is used to barrier coat for hydrogen. A metal container is heavier as a hybrid structure. The rear weight is very important for emission and performance of vehicle. Therefore the relation between metal and the fibre/matrix layers define the potential of lightweight strategy. Another aspect is the capacity of gaseous storage system, because the constructed size is enormously with the result of losing convenience. The designer can reduce the container dimension with the result that the range decreased or raise the working pressure up and create more weight. The costs of manufacturing are very important, too, because the yearly availability of fibre and matrix define the material costs. The new hybrid concept of a hydrogen container depends on the lightweight potential, storage capacity, material and manufacture costs.
