Which CO₂ price for the deployment of CO₂ capture, transport and geological storage techniques?

Whereas scenarios with ambitious objectives in terms of reduction of greenhouse effect gases are based on the use of techniques of CO₂ capture, transport and geological storage (for example in a scenario developed by IAE and published in 2012 in Energy Technology Perspectives), this study aims at proposing a large economic overview of these techniques applied to electric power plants, and at studying the CO₂ price level from which such equipped plants become competitive. This referred as CO₂ switch price. The obtained results are in controversy with specialised literature about this level. These differences are discussed and examined. The influence of the different fuels prices is then highlighted.
