Lighter, Cheaper Thermoplastic CNG Tanks for Automotive & Commercial Vehicle Markets



The technologies related to POLARIS are currently at TRL 6, and the objective is to overcome the 3 remaining barriers to demonstration at TRL 7/8:

  1. Materials: Optimise and upscale the carbon/polyamide tapes to meet cost, accuracy and property needs
  2. Process: Enhance the vessel-winding process to meet performance, weight and quality requirements
  3. Product: Upscale the manufacture of carbon/polyamide CNG tanks, to enable economic production

Overcoming these barriers will trigger our customers to start certification of the carbon/polyamide CNG tanks, as the next step in our commercialisation plan.


This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement no. 820567.
