Natural gas, a triple-A energy

Abundant, affordable and acceptable

Plan rapproché de tuyaux d'acheminement

Abundant, affordable and acceptable for the environment, natural gas plays a major role in the move towards an economy with lower CO2 emissions.


A natural energy form

  • Natural gas is created by the transformation of organic matter. There are abundant reserves and widely distributed underground and underwater deposits.
  • Gas is transported to consumptions areas in two ways:
    • In liquefied form (LNG) at a temperature of less than 160° in LNG carriers.
      LNG is then regasified in specialised terminals and injected into the transmission network.
    • In gaseous form in buried steel gas pipelines. The gas circulates at an average speed of 30 km/h under a pressure of 30 to 70 bars, provided by compressor stations installed every 150 km or so.
  • The gas is delivered to recipients connected to the transmission network:
    • Major industrial consumers and natural gas-powered electrical power plants.
    • Distribution networks that supply the general public and businesses.
    • Underground storage facilities and adjacent transmission networks.

The cleanest fossil fuel

Natural gas is lighter than hydrocarbons, Natural gas is lighter than hydrocarbons, containing one atom of carbon for every four atoms of hydrogen (CH4). It does not emit any soot, dust or smoke when burned. It generates 30% less carbon dioxide (CO2) than fuel oil and 45% less than coal, half as much nitrogen oxide (NOx) and very little sulphur dioxide (SO2), the cause of acid rain.


discreet infrastructures

Natural gas transmission, storage and distribution infrastructures are primarily underground. They are respectful of the surrounding landscape and minimise disruption for local residents. The ground-level installations are discreet, emit little pollution and successfully blend into their surroundings. For example, a pipeline 10 cm in diameter is sufficient to supply a town of 20,000 inhabitants.


The golden age of natural gas draws near

  • According to the International Energy Agency (IEA), natural gas consumption will double by 2030. It is expected to account for 25% of the global energy portfolio by 2035, compared with 21% today, giving production of 5,100 billion m3 (Gm3). 
  • Demand from emerging countries, the fight against climate change, the oil peak reached during 2006 according to the IEA, the doubts raised about nuclear energy following the disaster at the Fukushima power plant in Japan, and the excellent complementary attributes of natural gas and renewable energies (solar, wind, biomass) in electricity production are all growth factors.
