Advanced Thermoplastic Composite Materials for High-Pressure Hydrogen Storage in Trailers

Together with Air Liquide, Arkema has achieved a major advancement in hydrogen pressure vessel technology using bio-based Rilsan® PA11. Derived from castor oil, this polymer combines a low carbon footprint, excellent hydrogen barrier properties, minimal water uptake, and high ductility ideal for the liner, the vessel’s hydrogen containment layer.

To strengthen the structure, Arkema developed UDX® PA11 tapes, composed of continuous carbon fibers impregnated with PA11 and optimized for processability and mechanical performance. Their perfect compatibility with the PA11 liner enables a monolithic all-PA11 tank design, improving safety (preventing liner collapse), performance, and recyclability at end-of-life. This integrated solution sets a new benchmark for sustainable, high-performance hydrogen mobility.
