Hi Gregounet,
It's not cooler than Remoundounet
Except when one reads econological nonsense: CO2 capture is one of them.
The CO2 solution is to produce as little as possible (hence the massive effort needed in REs), and when you really have to (transport ...), reinject it for photosynthesis:
- natural (plantations, preservations of equatorial forests)
- artificial (for example, Christophe's oil-bearing algae)
But on this Saturday morning, we throw bottles at the sea

Hi Super Cool Rasta Remoundounet
Honestly, without pushing for the scientific considerations that you have just touched on, I have always considered this idea of capturing CO2 as an idiotic without a name.
This is a real nonsense since even without talking about the risks of massive releases, acidification of the soil and others, what will we do when we fill all the wells at CO2?
Finally, all that to say we are 100% agree all 2

It seems to me that landfills have an impermeable geological cover, of the marl or clay type, between the (rocky?) Reservoir and the surface.Rulian wrote:I have serious doubts about the burial of CO2.
Besides that the CO2 will find many flaws where to escape, I wonder how not to worry about the risk of massive acidification of soils above the landfill, which would turn the surface of the site into a real desert in a few years ...
It's nice to hide the dirt under the carpet, but it does not solve the problem and it could be dangerous ...
By the way, why acidification? The acidic forms of CO2 are only stable in water, right?
I do not understand your reasoning ...

Ben Bucheron, I think Rulian is right ...
a) besides the fact that it costs billions (proto pipo) the CO2 will finish, sooner or later I think to go back (necessarily by directly in the form of gas) to the surface ...
b) since we "know" how to bury it, pkoi limit emissions?
This is the only GOAL (media) of these factories I think ...
c) In short, it is a real job at SOURCE to do: how many m3 insulation could have been installed (with DIRECT impact on emissions) for the price of proto landfill plants? How much water doping installed?
d) It is indeed the CO2 dissolved in water (and not in the form of an acid) which acidifies it. A simple test: take a glass of soft drink (soda or mineral water), measure the acidity when "there are bubbles" and after a few days in the open air ....

Reason on what? I ask specific questions, I do not question his message ...Christophe wrote:Ben Bucheron, I think Rulian is right ...
Why, then ?Christophe wrote:a) besides the fact that it costs billions (proto pipo) the CO2 will finish, sooner or later I think to go back (necessarily by directly in the form of gas) to the surface ...
For the billions, I agree.
Never said the opposite, but you know as well as me why the industry works like this ...Christophe wrote:b) since we "know" how to bury it, pkoi limit emissions?

CO2 in dissolved form is not acid, it is the form HCO3- which is ...
However, I still do not understand this horror vision of "desert" ...

Yes Bucheron but to open a little debate: the question that kills: what is the cost in gray CO2 of a tonne of CO2 buried?
Bucheron, CO2 acidifies water well ...in form CO2 ... take the soda test if you do not believe me ...
ps: do not understand the remark on the "desert" ??

Well, I hope that the report is lower than 1 ...Christophe wrote: Yes Bucheron but to open a little debate: the question that kills: what is the cost in gray CO2 of a tonne of CO2 buried?
But, well, even if it would be only 0,5 T for 1, it is necessary to condemn this type of research, since anyway, and whatever happens, the Chinese (and other countries with coal resources) will use them until the end ?
No.Christophe wrote:Bucheron, CO2 acidifies water well ...in form CO2 ... take the soda test if you do not believe me ...

It's the same for your badoit!

Ah, I did not know ...
In fact if you have the saturation curve of CO2 water (mass if possible) depending on the T ° (or other) it interests me, I've been looking for years!
Ok for desert, it was old ...
