The sequestration of CO2, an interesting but expensive track ... - by pollux the 06 / 02 / 2006: 23: 04
Among the solutions conceivable to get rid of this CO2 so long, the most fashionable is to bury it, to sequester it geologically.
By sequestering means:
or transformed (chemically or physically) in a permanently stable material.
or burying it in geological reservoirs as we plan to do to store hydrogen.
Below we will discuss emerging technologies in storage CO2.
Unfortunately, this storage can only apply to fixed infrastructures. The outlook is most interesting for energy production activities. Transport activities (as long as the fuel cell has not become the standard) as well as agricultural activities are excluded, which limits its scope. Sequestration still offers interesting opportunities.
To permanently store the CO2 several techniques are possible and mastered.
The burial of CO2 includes four main steps:
separation (or capture)
compression,
transportation,
storage.
A study made by the IFP (French Institute of Petroleum), published on the Internet, provides an approximation of the storage costs of CO2.
this possibility only applies at the moment to the field of energy production and heavy industry

But do we really know how to capture it? at the exit of the exhausts for example?
And you what do you think?
