La filière captage et stockage du CO2

Abstract : INERIS is carrying out a research programme -named EVARISTE- devoted to the long-term effects of CO2 geological storage. The first issue that was highlighted in 2010 activities is the complete definition of risk scenarios. They include the different migration pathways within the underground system, but also mechanical or hydraulic effects and massive leakages at surface level, since the objective of INERIS is to harmonise risk assessment methods between surface and underground equipment (alike in the iNTeg-Risk project, devoted to new technologies). A specific care was given to the distinction between scenarios of “normal evolution” and scenarios of “altered evolution”. The second main issue was the study of 4 specific migration pathways and their possible impacts, both on overlying aquifers and at surface level (health effects in case of emanation and accumulation). A specific care was given in the study of impurities that are likely to be present in the injected CO2, such as trace metals or organic compounds. Given the specific assumptions that were made for this generic study, these impurities may have an impact superior to the impact of CO2 itself.
