CO2 rate for a Diesel Clio VS Peugeot iOn :-)

by Pear Belle Helene » 27/04/11, 09:56

Hello everybody

It has been a long time since I had come to post a quick question : Mrgreen:

So I tried a research before posting but I admit that the multiple open subject and the many answers that I read do not correspond to what I am looking for.

Here is my company to recently buy an Ion to ensure the shuttle between our different sites in town.
Up to this day it was a Clio diesel 70cv which was used for these urban journeys.

This Clio travels an average of 12 km per day, 47 weeks / year

So I'm looking to find out, among other things, how much CO2 will not be sent into the air thanks to Ion?
I hope you can help me and give me your opinion on this car.
I drove it yesterday to test and I admit it's amazing.

Thank you for your help. Have a good day. Hugs : Mrgreen: Pear Belle Helene

Oops not seen the question. As you waited a bit, I will give you a nice full answer

We must compare: indirect and direct CO2 rejection in the 2 cases;

Indirect = manufacturing, recycling.
Direct = CO2 from fuel and electricity production ("half" direct in fact, but more direct than indirect: p)

Already in global eco balance the i-Miev rejects on its battery 41gr / km Transportation-electric / Mitsubishi-Electric-emission miev-de-co2 41-g-per-km-t6280.html

As iMiev and iOn are twins (false but twins all the same), we can take the same figure.

Then add the gr CO2 per electric kWh: 90 gr / kWh for France.

1st approachExtract, Transportation-electric / Mitsubishi-Electric-emission miev-de-co2 41-g-per-km-t6280.html

It takes about 0.2 kWh / km (low estimate) to advance a small vehicle in town.

In France, the average is 90 g / kWh so 18 grams must be added to these 41 g or 59 g / CO2. So good! (thank you nuclear ...)

On the other hand, in Germany it is the catastrophe since the average is 600 g / kWh is in the end 161 g / CO2 (equivalent of a hdi consuming 6.2 L / 100)

Average of Europe 15: 0,46 CO2 kg / kWh elec.

2nd approach:

According Transportation-electric / list-and-price-of-electric-cars-2011-new-France-t10338.html the iMiev / iOn has a range of 150 km for a battery capacity 16kWh

Assume a 80% charge efficiency, we must consume 16 / 0.8 = 20kWh to 150km.

therefore consumes 0.13 kWh / km (lower than 1ere approach probably due to regenerative braking and other power management optimization, may be that the charging efficiency is lower as well, some).

So in the end it led to: 41 + = 0.13 90 * 53 gr / km in France.

It is interesting to see that the "CO2 displacement" part is much less important than the "gray" part, the proportion being from 1/5 to 4/5! Caution valid for France where nuclear provides a low rate CO2. Germany, 600 gr / kWh would have: 41 + = 0.13 600 119 * g / km is the equivalent of a recent average diesel car in economical driving but a small gasoline.

But as I often say to "defend" the electric car: there is not ONLY CO2 in life! The air pollution in the city kills more people than traffic accidents: Health-pollution-prevention / the-dead-of-the-pollution-t1901.html

Also to be completely honest in the process we must also take into account the embodied energy of the thermal car. It is recognized that manufacturing is about the equivalent of 20 000 km covered (varies but average): new-transport / manufacturing-and-a-car-and-environment-figures-t8713.html

(...) About 2.5 Tons CO2 / car manufactured! 2500 kg CO2 ca represents 140 g / km approximately 18 000 km covered !!

Over a lifetime of 200 000 2.5 km these T CO2 are therefore an increase of 2500 / 200 12.5 = gr / km

Let's say that recycling is the same (which seems credible) or 25 gr / km.

Interestingly, we find ourselves in the same proportion but reversed:

Thermal = 1 / 5 gray CO2, 4 / 5 of propulsion CO2
Electric = 4 / 5 gray CO2, 1 / 5 CO2 of propulsion (in France)

So in the end, we must increase the rate CO2 / km of thermal car 25 gr / km to take into account the embodied energy / recycling.

So in your case, pear, there is more to applying these figures!
