摘要

Carbon dioxide (CO_2) capture and storage (CCS) in geologic formations is generally regarded as a key aspect of a broader carbon management technology portfolio for addressing climate change while simultaneously minimizing negative impacts on the economy. When evaluating CCS opportunities, several factors, including what kind of source will provide the CO_2, the volume of CO_2 produced per day, and key geographical and geophysical characteristics of the candidate reservoir, should be weighed as part of a cost-benefit analysis. The risk of tectonic seismicity should also be examined, and expressed in terms of costs that can be incorporated into the decision-making process. Tectonic seismicity, or natural seismic activity, poses potential dangers to CCS surface equipment and infrastructure, such as compression, surge tank, and injection facilities and pipelines, and the cost of mitigating this risk—via strict construction codes and tighter operational rules—should be considered alongside other factors when evaluating prospective storage options. As a first step, the authors develop a method to compute costs associated with replacing capital equipment. The authors conclude that, while the costs of mitigating the effects of a seismic event should be incorporated into costing analyses associated with site evaluation, for most of the United States, the annual risk of significant damage is very low, and the costs associated with seismic risk will likely have only a very small impact on total project costs. However, for a few locations in the United States, incorporating these risks might affect the decision to store CO_2 in geologic formations near that specific locale.
