In CO_2 geologic storage, even if containment of CO_2 plume is ensured, continuous long-term injections for more than several decades can potentially build up groundwater pressures in extensive regions. In this study, with the massively parallelized computation on a highest performance supercomputer in Japan, the Earth Simulator, a comprehensive, large-scale numerical simulation of CO_2 geologic storage that predicts not only CO_2 migration but also its impact on regional groundwater flow was performed. As a hypothetical case study, a simulation of industrial-scale injections of CO_2 at the Tokyo Bay was presented.
