AS 24 offers a diversified range of fuels thanks to the installation of Compressed Natural Gas at its service stations in France and Europe. CNG is the first alternative fuel for HGVs that limits the emission of pollutants (compliance with the Euro VI anti-pollution standard) and reduces noise pollution. Moreover, it is an economically viable solution.


CNG or « Compressed Natural Gas » is a mixture of light hydrocarbons stored at high pressure. It is derived from natural gas naturally occurring in porous rocks and composed mainly of methane.

CNG is a fuel used for all vehicles (from light vehicles to HGVs). Many types of engines are thus compatible for transport professionals.


More than ever, the dynamic of the energy transition has started. It is reflected in activities and measures to reduce polluting emissions and greenhouse gases.
The ambition is on European, national and local levels, with communities increasingly involved in cleaner energy.

Europe’s ambitious objectives: “3 x 20” by 2020

  • 20% reduction in greenhouse gas emissions compared to 1990
  • 20% improvement in energy efficiency
  • 20% integration of renewable energies into total energy consumption

Air quality: a major challenge in France

To improve air quality, all public actors undertake to reduce:

  • emissions of nitrogen oxides (NOx)
  • particles

The transport sector is particularly concerned by these issues.

In France, the Energy Transition Act introduces new measures to enable communities to combat air pollution. French legislation complies with European standards on the reduction of particles and nitrogen oxides (NOx). The authorities are now able to restrict the circulation of the most polluting vehicles on their territory thanks to the Crit'Air tags.

The fight against air pollution: the advantages to using CNG


If a CNG vehicle is more expensive to buy, it can become more profitable than Diesel or gasoline depending on the price of fuel, distances travelled and the taxation in force.

« A competitive TCO (total cost of ownership) »


CNG technology reduces noise by half compared to diesel HGVs. An advantage when travelling through cities or by night.

« Reducing noise by half »


CNG HGVs can travel an average of 400km, which is why it's mainly used for urban and regional applications. Commercial vehicles, on the other hand, have more than 600 km of autonomy by combining gasoline and CNG.

Pollutant emissions

With very little particles and less nitrogen oxide (NOx) when compared to diesel, HGVs and CNG commercial vehicles all meet the standard in force since 1 January 1st, 2014: EURO VI for HGVs and EURO 6 for commercial vehicles.

« Low levels of NOx and particles »

In summary: Even if a CNG vehicle is more expensive to buy, it can become more profitable than Diesel or gasoline depending on the price of fuel, distances travelled and the taxation in force


To better support transportation professionals, TotalEnergies and AS 24 unite their networks in order to offer a multi-energy service with the installation of CNG stations optimised according to their customers' needs and a cross-acceptance of their cards.

In order to ensure a larger and quickly operational network of CNG stations for all their users, the TotalEnergies GR and AS 24 EUROTRAFIC cards are accepted on both networks. (The contract is non-binding).


A network of CNG stations for road professionals

With AS 24, your CNG supply is simple and fast.

What you get:

  • competitive rates. 
  • loading lanes that are adapted to HGVs.
  • a distribution optimised for professionals with fast filling time and NGV1 or NGV2 nozzles to choose from

Recommendations for use

CNG does not pose any additional hazard as compared to Diesel or gasoline. All connections are sealed without any risk of vapours or splashes. Of course, as with other fuels, it is essential to follow the safety instructions.

General safety instructions at the station

  • Stop the engine
  • Do not smoke or bring a hot source near the vehicle
  • Do not use your telephone

Two additional instructions for CNG:

  • Only fill authorised tanks
  • Never use an adapter between the tank and the nozzle

Getting CNG is different from a Diesel, but just as simple. Just change a few habits! To support drivers and help them become familiar with the new stages of refuelling, a manual is available on the side of the flow metre.
