Carbon sequestration is considered essential in attaining climate goals set forth by the Paris Climate Accords, and the recent incentives through the 45Q tax credit provides financial support for carbon sequestration efforts. With growing interest in carbon sequestration, the Geoanalytical Economic Evaluation of Saline Storage (GEESS) system was developed for Department of Energy’s National Energy Technology Laboratory. GEESS is a comprehensive toolset that incorporates geologic, economic, and scientific data to characterize 57 geologic formations for carbon sequestration. The objective of GEESS is to provide a characterization of the nation’s saline storage resources at a greater level of detail than currently available. This includes the incorporation of depth and thicknesses of the formations, as well as information regarding porosity, permeability, salinity, temperature, and pressure. The geologic dataset is presented in a 5-kilometer grid, which is a marked improvement over other datasets which generalize the entirety of geologic formations. Geologic formations are often heterogeneous, and GEESS takes a step forward in characterizing the heterogeneity of saline aquifers that are suitable for carbon sequestration through the development of spatial databases.
