Economic modeling of the CO2 transportation phase and its application to the Duero Basin, Spain

Abstract

Carbon capture and storage is a viable option to reduce greenhouse gas emissions. Although capture and geological storage of CO2 are the major forms of research, CO2 transportation should be also considered in the entire chain. There are still some issues that require a more accurate definition, especially in economic aspects. In this study, we explore concepts such as the uses of a storage structure for a single source with, for instance, an individual transportation line, and the use of a centralized model using a geological structure for several co2 emitters. This model has been applied in a given region of Spain, in order to determine the maximum distance between the sources and the potential areas for storing CO2, using a geographical information system to evaluate the data. Moreover, sensitive analysis was performed in order to provide a better understanding of the economical implications of CO2 transportation.
