过去，潜在的二氧化碳储存地点的清单纯粹是根据这些地点的二氧化碳溶解度来编制的。然而，在其中一些地方，注入二氧化碳在商业上是不可行的，因为它们的平均渗透率很小。在主动存储活动期间以及在被动存储活动的第一部分中，一些注入的二氧化碳将处于自由超临界状态，并且将需要具有具有某种泄漏点的陷阱类型配置的存储位置。讨论了根据影响空间和最大增压计算理论最大储能的方法；基于注水能力的储能；以及地质圈闭的储能效率。这是在离岸技术会议上发表的一篇论文的摘要--“变革的浪潮”(休斯顿，德克萨斯州，2008年5月5日)。
In the past, lists of potential CO2 storage locations have been compiled purely on the basis of the capacity of the locations in terms of their CO2 solubility. However, in some of these locations, the injection of CO2 is commercially unfeasible because of their small average permeability. During the active storage activity and in the first part of the passive storage activity, some of the injected CO2 will be in a free super-critical state and will need a storage location that has a trap type of configuration with some sort of leak-off point. A discussion covers a method to calculate the Theoretical Maximum Storage Capacity based on affected space and maximum pressurization; the storage potential based on injectivity; and the storage efficiency of the geological trap. This is an abstract of a paper presented at the Offshore Technology Conference - "Waves of Change" (Houston, TX 5/5-8/2008).
