Fuel Tanks for Biofuels

It is well known that Plastic Fuel Tanks (PFT) are fully compatible with all kinds of bio-fuel (ethanol, bio diesels). Their advantage lies in the fact that the material they are made of is totally corrosion-resistant.

The use of PFT is likely to increase as some targets have been set for the production of bio-fuels at EU level. Indeed, since 2004, the expansion of the production of bio-fuels is regulated by Directive 2003/30/EC, which should have been transposed into national laws since 31 December 2004. This Directive has set up targets for the production of bio-fuels for the year 2010.


Besides, a consortium consisting of organizations representing the European oil industry (CONCAWE), the European Council for Automotive R & D (EUCAR) and the Joint Research Center of the European Commission (JRC Ispra) investigated 75 different pathways from primary energy sources.

Alternative motor fuels have the technical potential to gain significant market share within the next decades, even exceeding the 20% substitution target suggested by the Commission for 2020.

'Biofuel' is a generic term and used for different fuel compositions. PlasFuelSys members understand under this term in this statement Ethanol containing fuels and Biodiesel coming from different vegetable sources.

The fuel tank producers understood the need to analyze the Plastic Fuel Tank (PFT) and accepted the challenge to demonstrate the compatibility of the PFT against Biofuels. However, even before Biofuels were in discussion and on the market, the requirements for a PFT have foreseen the full compatibility and functionality for all fuels usual in trade. Therefore, with the system knowledge and experiences, the PFT producers performed on their own or initiated together with competent partners tests to proof

  • Material Compatibility
  • Evaporative Emissions
  • Functionality of Fuel Systems

Material compatibility, calculable evaporative emissions and a given functionality of the PFT as well as an ensured corrosion-free tank shell are clear advantages of a Plastic Fuel Tank. The barrier COEX technology used in current and future systems is a fit-to-function technology also for next generation’s requirements.

As a result of the short term and long term investigation, Plasfuelsys members conclude that Biofuels are not a challenge for a Plastic Fuel System – it’s just the opposite: A Plastic Fuel Tank is the adequate answer to Biofuels.
