The Use of Saline Aquifers as a Target for Deep Geologic CO 2 Storage in Israel

Geologic carbon dioxide capture and storage (CCS) is considered as a promising technology for the reduction of atmospheric emissions of greenhouse gas in the short run. Here we summarize the advances made over the last decade in research of CO2 storage in Israel. This includes estimates of the storage potential of varying complexities, dynamic simulations of injection scenarios to elucidate storage capacity and its security, laboratory experiments to investigate various physical and geochemical aspects of the storage process as well as a small-scale injection experiment designed to in situ estimate capillary trapping. Studies revealed a vast storage capacity, which is found in three deep saline aquifers in the Negev. This shows that CO2 storage can be used to reduce greenhouse gas emissions in Israel and its potential and dynamics should therefore be further investigated.
