About Polaris


There are currently 1.3 million Compressed Natural Gas (CNG) vehicles on Europe’s roads, expected to rise to 15 million by 2030. Customers such as Audi, Daimler and Volvo have set a target 10% weight and cost reduction for CNG tanks, to increase efficiency and reduce vehicle cost.

Most CNG tanks are made from a metal or polymer liner, over-wound with a carbon/epoxy composite, but:

  • Wet-winding of carbon/epoxy is slow, so limits cost-effective production
  • Their properties vary by up to 10%, so excess material is used to compensate

To meet the customer targets, Plastic Omnium has developed a new process for the fast, efficient production of CNG tanks, using 8-axis robotic tape placement cell from MF Tech, and high quality carbon/polyamide tape developed by Coventive Composites.

Together, these technologies can reduce CNG tank weight by 10% and cost by 20%.
