Abstract : It seems increasingly likely that atmospheric greenhouse gases concentration will overshoot the recommended 400 ppmC02 target. Therefore, it may become necessary to use bioenergy with carbon capture and storage technologies (BECCS) to remove CO2 from the atmosphere. This study evaluates the possible deployment of BECCS in the power sector with the bottom-up multiregional op-timization model TIAM-FR. The results of the long term modeling exercise sug-gest that to achieve a stringent target, BECCS technology represents an environ-mentally and economically viable option. The regional analyze shows that industrialized countries will develop CCS mainly on biomass sources while CCS on fossil fuel is largely deployed in fast developing countries.
