Conclusion

This article highlights the technological advances and challenges associated with hydrogen storage in Type IV tanks, critical for a sustainable energy economy. Type IV tanks, composed of a composite shell and a polymer liner, offer significant advantages in terms of lightness, strength and safety. These features are essential to meet the demands of the transport industry and industrial applications, where performance under high pressure is paramount.

Manufacturing methods such as filament winding, helical winding, circular winding and polar winding enable tanks to be strengthened according to the different stresses to which they will be subjected. The incorporation of advanced polymers such as PA11 and PA12 in liners improves permeability and durability, although these materials present drawbacks in terms of cost and manufacturing process.
