“…According to Shangguan a rubbery polymer changes its permeability properties while it is compacted due to high pressure, this is expected to occur for Arnitel™ EB460 22 . Further Fujiwara et al examines hydrogen storage tanks with high‐density polyethylene inner‐liner and highlights that hydrogen permeability deteriorates with the increase of gas pressure 23 . These tests were performed up to 900 bar and reveals similar findings as we have found.…”

The permeability properties of composite gas cylinders for breathing gas with polymer inner‐liner are investigated. The cylinder wall can be described as a composite membrane consisting of two layers. The permeability properties of the cylinder are presented as permeability coefficient and permselectivity. Deviation from the expected gas components might lead to incidents and potentially harmful situations when breathing gas from a compressed gas cylinder. Hence, gas permeability and potential changes in gas composition, must be considered when choosing cylinder materials. Cases of decompression sickness initiated this study. Experimental data show that pressure and oxygen fraction in the gas cylinder drops and that the permeability coefficient varies depending on the inner pressure. Permeability coefficients of 0.62–0.90 Barrer for oxygen and 0.44–0.56 Barrer for nitrogen are measured. Cracks in the inner‐liner have caused an accentuated drop in of oxygen fraction and pressure.

“…It can cause a compaction of the sample, which caused a slight decrease of the permeability. This phenomenon was described for concrete samples in [19], as well as for the polymer materials, where hydrostatic compression effect occurs [15]. However, the scale of permeability decreased, as well as mechanism responsible for it, is different.…”

Energy production from renewable energy sources is not stable and any fluctuations in energy productions need to be eliminated with underground energy storage. Demand of underground gas storage will be increasing, due to the switching to green energy, while the availability of underground storage sites, especially salt caverns suitable for hydrogen storage, is limited. The purpose of this paper is to compare the hydrogen permeability of different materials and select a proper liner material for hydrogen storage in Liner Rock Caverns or post mine workings. A variety of materials, like concrete, polymer concrete, epoxy resin, salt rock, and mudstone, were tested for gas permeability/hydrogen diffusion, using the combined Steady-State Flow/Carrier Gas methods. Results are shown in different units, providing the opportunity to compare the results with literature data. The permeability value of investigated epoxy resin is comparable to the salt rock (after creep process), which makes the epoxy resin a promising sealing liner for hydrogen and potential substitution of stainless-steel in Lined Rock Cavern (LRC) gas storage.

“…Furthermore, increasing the barrier properties, diffusivity, and minimizing the gas solubility would decrease the pressure accumulation inside the material during the gas decompression and possibly lower the damage. Recently, Fujiwara et al [48] developed a test method to measure the transport properties of polymeric materials, especially in the equilibrium state under high-pressure hydrogen up to 100 MPa of pressure. Similar test set-ups and measurements will help to obtain precise and reliable information on selecting the materials and designing the components for high-pressure hydrogen energy systems.…”

“…Similar test set-ups and measurements will help to obtain precise and reliable information on selecting the materials and designing the components for high-pressure hydrogen energy systems. [48] Generally, the fillers enhance the mechanical properties of polymers. Therefore, a better filler strategy would balance the mechanical properties and barrier properties, which can possibly optimize the durability of a sealing component in high-pressure hydrogen atmospheres.…”

A Review on Applicability, Limitations, and Improvements of Polymeric Materials in High-Pressure Hydrogen Gas Atmospheres

et al. 2021

Typically, polymeric materials experience material degradation and damage over time in harsh environments. Improved understanding of the physical and chemical processes associated with possible damage modes intended in high-pressure hydrogen gas exposed atmospheres will help to select and develop materials well suited for applications fulfilling future energy demands in hydrogen as an energy carrier. In high-pressure hydrogen gas exposure conditions, damage from rapid gas decompression (RGD) and from aging in elastomeric as well as thermoplastic material components is unavoidable. This review discusses the applications of polymeric materials in a multi-material approach in the realization of the "Hydrogen economy". It covers the limitations of existing polymeric components, the current knowledge on polymeric material testing and characterization, and the latest developments. Some improvements are suggested in terms of material development and testing procedures to fill in the gaps in existing knowledge in the literature.
