Abstract
El almacenamiento geológico profundo (AGP) es una de las iniciativas que, en el ámbito internacional, está cobrando mayor relevancia para reducir las emisiones antropogénicas de CO2 a la atmósfera. En territorio español, el estudio de las posibilidades de AGP de CO2 se está canalizando a través del Proyecto Singular Estratégico “Tecnologías avanzadas de generación, captura y almacenamiento de CO2” del MEC y, como una parte de este proyecto, se han estudiado las posibilidades que ofrece la Cuenca del Ebro de cara al almacenamiento definitivo de CO2, mediante la reinterpretación de la información de sondeos del Archivo Nacional de Hidrocarburos, gestionado por el IGME. Se han seleccionado una serie de formaciones que, por sus características relativas a disposición, extensión, profundidad y porosidad, podrían constituir un futuro almacenamiento, prestando también especial atención a las formaciones sello, que garantizarían la estanqueidad de los diferentes almacenes. Se proporciona una estimación de la capacidad de almacenamiento de cada formación, que si bien es aproximada, si puede ser un dato útil para la toma de decisiones futuras.
Deep geological storage (DGS) is one of the more relevant international initiatives in order to eliminate or reduce the anthropogenic CO2 emissions to the atmosphere. The study of the possibilities of DGS of CO2 inside Spanish territory is being performed through the Strategic Singular Project “CO2 generation,capture and storage advanced technologies”, of the MEC. The potential final storage of CO2 in Ebro Basin, has been studied through reinterpretation of deep boreholes information from the National Hydrocarbons Archive, managed by IGME. A number of formations have been selected that, by their position, extent, depth and porosity, could be a future storage. The study has also been conducted considering the characteristics of the geological formations above the CO2 storage formations so as to guarantee the sealing of the storage. The study includes the approximate estimation of the storage capacity for each formation, which can be useful in future decision making.
