Protection Level

Type IV tank manufacturing by RTM technology 

Entity:

Manufacture of a tank to store compressed H2 at pressures of 700 bar (type IV). The tank consists of a polymer liner and a composite structural coating. The decrease in permeability and interaction of the liner with hydrogen is studied by means of polymer modifications and additivation. RTM (resin transfer moulding) technology is used for the structural coating, which is not very common in the market today, with most options being manufactured by filament winding. The interest in using RTM is its higher production rate to try to bring this form of energy storage closer to the mobility sector. 

Challenges met

The research is aimed at: 

  • Improving the leak-tightness of hydrogen tanks. 
  • Improving the mechanical performance of the tanks (reducing their weight). 
  • Improving the production rate of the tanks.  

Scope of application

Automotive sector. In particular to hydrogen mobility with fuel cells. It aims to increase the storage capacity of this gas to increase the autonomy of vehicles.
