TL;DR: In this article, a systematic approach is proposed for the assessment and selection of method and sites for CO2 sequestration in geological media, and the range of sedimentary basins suitable for CO 2 sequestration is significantly reduced if these criteria and climatic conditions, accessibility, infrastructure and cost of CO2 capture and injection are taken into account.

TL;DR: In this paper, a set of definitions and methodologies for the assessment of CO2 storage capacity in geological media is presented, including coal beds and deep saline aquifers, and the level of detail and resolution required in the data make reliable and accurate estimation of the storage capacity of these media practical only at the local and site-specific scales.

TL;DR: In this article, the authors discuss the risks associated with CO2 capture and geological storage, and the potential for acute or chronic CO2 leakage from a CO2 storage site is discussed.

TL;DR: A general approach to evaluating sedimentary basins for CO2 disposal is presented in this paper, exemplified for the case of the Alberta Basin in western Canada where a wealth of geological and hydrogeological data from more than 150,000 wells drilled by the oil industry allows for a proper estimate of the basin potential for long-term storage of CO2 captured from fossil-fuelled power plants.

TL;DR: In this article, the authors developed a methodology for estimating the ultimate CO2 sequestration capacity in solution in aquifers and applied it to the Viking aquifer in the Alberta basin in western Canada.
