For the high‑pressure storage (700 bar) of on‑board hydrogen, current tanks are made of a composite based on thermoset resin (epoxy), which must be cured for several hours after winding. Elium® liquid thermoplastic resin, combined with carbon fibers, offers the same strength properties with much better industrial efficiency. Its polymerization under the effect of UV is carried out during the winding process, saving considerable time and energy. This technology, which could see its first applications for light vehicles on the market in 2023, also offers excellent recycling possibilities for composite tanks at the end of their life, while thermoset resins are still very hard to recover.
