“…Acceptable rates of leakage in the past have been expressed as a percentage of the total volume injected and typically range from 0.01 % per year (1 % over 100 years) to 0.001 % per year (1 % over 1,000 years) (Bowden and Rigg 2005;Shuler and Tang 2005). For a CO 2 storage site which annually releases 0.001 of the amount stored, effectiveness is around 60 % after 1,000 years.…”

Although CO 2 geological storage has been recognized as an effective strategy to lower carbon emissions directly, there are no suitable guidelines for safety risk assessment of CO 2 geological storage projects in deep saline aquifers in China and elsewhere. When CO 2 is injected into deep saline aquifers, stratigraphic and structural trapping is the major basic mechanism controlling CO 2 storage capacity and migration in reservoirs. Therefore, a safety risk assessment method is proposed in this paper using perspectives from hydrogeological and environmental geology. The uncertainties and risks consist of CO 2 leakage, ground deformation, and induced earthquakes. Identifying and assessing potential risks are the first and most important step in the process of risk assessment. Based on the identification of risks of CO 2 geological storage projects, we built an elementary risk evaluation index system in an analytic hierarchy process framework. Meanwhile, the possibility of occurrence and damage to the environment and public caused by CO 2 leakage, ground deformation, and induced earthquakes was analyzed in detail, and current risk criteria were also summarized. Furthermore, using the Shenhua CO 2 Capture and Storage Demonstration Project as a case study, we performed a risk identification and evaluation by using qualitative or semi-quantitative methods in sequence, as well as developing the related preliminary risk management measures. This method and case study for short-term safety risk assessment could provide a guideline for site selection, injection design, and monitoring of CO 2 geological storage projects in deep saline aquifers.

“…Sub-seabed storage leaks are possible over time (Hawkins, 2004). For instance, acceptable rates of leakage have in the past been expressed as a percentage of the total volume injected and typically range from 0.01% per year (1% over 100 years) to 0.001% per year (1% over 1000 years) (e.g., Bowden and Rigg, 2005;Shuler and Tang, 2005).…”

“…The assessment was iterative, basin specific, detailed, and incorporated prior estimates from individual large oil and gas fields and basinwide studies of hydrocarbon systems [9]. These results were sufficiently specific to produce a preliminary risk analysis and ranking of prospective candidate CO 2 storage formations (e.g., [12,18]). The results of this modest effort have already been put to use in helping to inform the siting of a proposed liquefied natural gas (LNG) plant, proposed CO 2 storage projects associated with natural gas production, and the creation of the follow-on public/private sector collaborative geological sequestration project known as the CO2CRC.…”

The costs for carbon dioxide (CO 2 ) capture and storage (CCS) in geologic formations is estimated to be $6-75/t CO 2 . In the absence of a mandate to reduce greenhouse gas emissions or some other significant incentive for CCS deployment, this cost effectively limits CCS technology deployment to small niche markets and stymies the potential for further technological development through learning-by-doing until these disincentives for the free venting of CO 2 are in place. By far, the largest current fraction of these costs is capture (including compression and dehydration), commonly estimated at $25-60/t CO 2 for power plant applications followed by CO 2 transport and storage, estimated at $0-15/t CO 2 . Of the storage costs, only a small fraction of the cost will go to accurate geological characterization. These one-time costs are probably on the order of $0.1/t CO 2 or less as these costs are spread out over the many millions of tons likely to be injected into a field over many decades.Geologic assessments include information central to capacity prediction, risk estimation for the target intervals, and development facilities engineering. Since assessment costs are roughly 2 orders of magnitude smaller than capture costs, and assessment products carry other tangible societal benefits such as improved accuracy in fossil fuel and ground water reserves estimates, government or joint privatepublic funding of major assessment initiatives should underpin early policy choices regarding CO 2 storage deployment and should serve as a point of entry for policy makers and regulators. Early assessment is also likely to improve the knowledge base upon which the first commercial CCS deployments will rest.
