“…After validation of the proposed test rig concept for homogeneous thermoplastics at room temperature, further validation testing must be done in order to qualify the setup for the measurement of FRT -again, both at room temperature and at cryogenic conditions. Validation is planned to proceed with the reproduction of recently published permeability data of FRT at room temperature [15]. For that, a…”

The need to decrease the gross weight of cryogenic hydrogen fuel systems in future zero emission mobility leads to increasing activities in the field of cryogenic lightweight engineering. Fibre reinforced thermoplastic composite materials (FRT) are considered for cryogenic applications despite their bias towards permeation. However, permeation through plastic materials is of major concern in cryogenic applications. Even tiny fluxes can very much compromise the insulating power of high vacuum spaces required for insulation of cryogenic systems such as tank structures or transfer lines. Hence, it is essential to qualify those FRT in terms of their hydrogen permeability for future usage in mobile cryogenic applications. The conventional concepts for measuring permeability in plastic materials are not sufficient for cryogenic measurements of FRT as shown in a previous paper. For that, a novel laboratory test rig concept was proposed. In this paper, we validate this concept and show its eligibility for measuring permeation of hydrogen through thermoplastic materials. Therefore, we report results of helium permeation through polytetrafluoroethylene (PTFE) at room temperature and compare those results to literature permeability data.

“…Projected performance and cost of CSVs of both type IV and type V. applied pressures were, in the majority of tests, 10 MPa for He, Ar, N 2 , which is far from the 70 MPa standard pressure of the present hydrogen CSVs. In the last years, many interesting experimental works have been oriented toward realistic condition of pressure [8,9]. It has been found by Fujiwara et al that the polymers used as liners (LDPE, LLDPE, HDPE, and MDPE) suffered fracture during the decompression process after hydrogen exposure was found.…”

This chapter explores the optimization of type 4 pressure vessels used for hydrogen storage, focusing on carbon fiber-reinforced composites produced through filament winding. Many studies delve into the intricacies of the winding process to enhance the structural integrity of the vessels. Progressive failure analysis is employed to identify potential weak points and failure modes, guiding the development of optimal designs for improved safety and performance. Additionally, the chapter highlights the importance of considering recycling strategies in the design phase to address environmental concerns associated with composite materials. The findings contribute to advancing sustainable practices in the production and life cycle management of hydrogen pressure vessels.

“…The permeability of TLCP is comparable to that of blow-molded PET. Moreover, Condé-Wolter et al [76] found that there were micro-cracks and other defects in the weld of the liner material, which would affect the mechanical properties and increase the hydrogen permeability coefficient of the liner. In order to improve the hydrogen barrier properties of the liner, fillers can be added to the polymer.…”

Type IV hydrogen storage cylinders comprise a polymer liner and offer advantages such as lightweight construction, high hydrogen storage density, and good fatigue performance. However, they are also characterized by higher hydrogen permeability. Consequently, it is crucial for the polymer liner material to exhibit excellent resistance to hydrogen permeation. International organizations have established relevant standards mandating hydrogen permeation tests for the liner material of type IV on-board hydrogen storage cylinders. This paper provides a comprehensive review of existing research on hydrogen permeability and the hydrogen permeation test methods for the polymer liner material of type IV on-board hydrogen storage cylinders. By delving into the hydrogen permeation mechanism, a better understanding can be gained, offering valuable references for subsequent researchers in this field. This paper starts by thoroughly discussing the hydrogen permeation mechanism of the liner material. It then proceeds to compare and analyze the hydrogen permeation test methods specified by various standards. These comparisons encompass sample preparation, sample pretreatment, test device, test temperature and pressure, and qualification indicators. Then, this study offers recommendations aimed at enhancing the hydrogen permeation test method for the liner material. Additionally, the influence of test temperature, test pressure, and polymer material properties on the hydrogen permeability of the liner material is discussed. Finally, the influences of the test temperature, test pressure, and polymer material properties on the hydrogen permeability of the liner material are discussed. Future research direction on the hydrogen permeability and hydrogen permeation test method of the liner material of the type IV hydrogen storage cylinder has been prospected.
