Sequestration CO2, an interesting track, but expensive ...

Among the possible solutions to get rid of this cumbersome CO2 durably, 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 imprison 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 be applied to fixed infrastructures. The prospects are 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 their scope. Sequestration still offers interesting opportunities.

    To permanently store the CO2 several techniques are possible and mastered.

    Burying CO2 includes four main steps:

  • separation (or capture)

  • compression,
  • transportation,
  • storage.
  • A study by the IFP (Institut Français du Pétrôle), published on the Internet, provides an approximation of the costs of CO2 storage.

    this possibility only applies for the moment in the field of energy manufacturing and heavy industry
