The largest source of primary energy, coal




by jlt22 » 09/08/09, 22:56

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 !!!!!!

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 !!

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.

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? : Cheesy:

It does not preclude that I am not favorable to this kind of projects ... :|
