Gas is the fuel that emits the least CO2




by Korben Dallas » 18/12/09, 20:25

Yesterday I received a letter from GrDF proudly announcing:
The combustion of natural gas produces mainly water vapor and CO2 in small quantities. It is the fuel that generates the greenhouse gas fraction, 30% to 50% less CO2 emissions than the other fuels.

Since you are told that fossil energies, it does not pollute (little?)!

Another sentence:
According to the Life Cycle Assessment (LCA) approach, natural gas heating emits almost 3 less CO2 than any new electric heater installed.


I think they do not miss air at GrDF : Evil:

I find they do not lack air at GrDF : Evil:


Fortunately because it takes for the combustion : Cheesy:

Hi friends,

Scientistically, they are right ... methane is even the champion since it releases only a CO2 for 2H2O.

GDF gas is more like C4H10 butane or C3H8 propane.

That said, gas is a pollutant to GHGs, requires a lot of energy to be transported (rolling in gas pipelines) ... and the gas they sell is fossil ... and most importantly, it is Vladimir who holds the tap. :?

City gas is methane!

One can even buy methane detectors to be placed high to detect leaks since methane is lighter than air.

Well yes the CH4 is the alkane closer to the H2 :)

Oh no GDF sells CH4 (which remains gaseous even under storage pressure), butane propane is "petroleum" gas which is liquid sotcké!

yes, "town gas" is more than 80% methane.

But propane and butane is also an important activity of SFM. They are often liquefied for transport (energy-intensive too!)

Butagaz is one of the competitors of GDF, there is also Antargaz, Primagaz, Totalgaz.

In addition to "natural gas" (city, mainly CH4) GDF also distributes butane / propane.

So we know very well now who does what, between GrDF and GDF Suez ... : Cheesy:

That's what I thought ... but then in what form (commercial) GDF sells propane butane?

in its city gas, GDF or Suez can put 15% residual ethane, propane or butane.

For the bottles, I think that GDF does not do it ... That says to check.

I think the others make bottles or deliveries in pressure tanks to private individuals.
