Geographical relationship between
sources and storage opportunities
Global distribution of large stationary sources of CO2 (Based on a compilation of publicly available information on global emission sources, IEA

Geographical relationship between
sources and storage opportunities
Storage prospectivity
Highly prospective sedimentary
basins
Prospective sedimentary basins
Non-prospective sedimentary
basins, metamorphic and
igneous rock
Data quality and availability vary
among regions
Prospective areas in sedimentary basins where suitable saline formations, oil or gas fields, or coal beds may be found. Locations for storage in
coal beds are only partly included. Prospectivity is a qualitative assessment of the likelihood that a suitable storage location is present in a given
area based on the available information. This figure should be taken as a guide only, because it is based on partial data, the quality of which may
vary from region to region, and which may change over time and with new information (Courtesy of Geoscience Australia).
