It's a unanimous fact, coal is the largest energy reserve
primary school in the world.
We are told that by storing the CO2 it produces, it will make it a clean energy .......... to SEE !!!!!!

Coal is a fossil fuel so non-renewable. I move the subject!

By storing it where and how? like mouai ...... to SEE

Totally agree with you lumberjack ....

Pipo ... it's just to "reassure" people that ... when you see the cost of geological re-burial, it's nonsense! Not to mention the risk of "leaks" ...
Better a microalgae plant: we reuse the CO2 internally to make a value-added product and not a pure loss !!

you should try the christophe policy, your arguments are very convincing.

Here is an interesting document on coal combustion:
Is charcoal a satisfactory fuel?
by G. Rossier & W. Micuta
In most developing countries charcoal is the main fuel. The authors show that under Third World conditions at least 10 kg of wood must be destroyed to produce 1 kg of coal. They then show that, using a furnace

Beyond cost, the problem that many people are unaware is that concentrating CO2 leads to a significant increase in the acidity of the environment. How will the cavities behave on a geological scale, no one knows.

+ 1 associated with a Laigret installation would be perfect.

I guess people who think about these kinds of solutions have "
a tiny bit"leaning on the question by studying the reactions of the different fields considered, don't you think?
It does not preclude that I am not favorable to this kind of projects ...
