摘要

政府间气候变化专门委员会得出结论,二氧化碳捕集与封存(CCS)对于稳定气候的能源转型至关重要。在CCS中,捕获的二氧化碳被隔离在沉积盆地的含盐含水层中。CO2储存量和注入速率是咸水层地质的函数,具有不确定性。为了最大限度地减少这种不确定性的影响,CCS项目可以包括备用计划,例如将地质二氧化碳储存(GCS)地点与现有的二氧化碳提高采收率(CO2- eor)作业共同安置或靠近。这些“堆叠储存”项目可以对冲含盐地层性能的不确定性,因为在发生意外事件(例如,注入能力下降)时,捕获的二氧化碳可以注入到任何一个位置。在这里,我们研究了在俄克拉荷马州开发CCS网络的可能性和后果,这些网络可以修改为堆叠存储。我们发现叠储在俄克拉何马州是可行的,但拥有成本最低的盐储资源的县没有现有的二氧化碳提高采收率作业。在系统层面,我们发现在有CO2-EOR项目的县部署GCS的成本略高(例如,1美元/吨二氧化碳到5美元/吨二氧化碳)。增加的费用主要是由于二氧化碳运输成本的增加,因为从成本最低的来源捕获二氧化碳需要数百公里的额外管道。总的来说,我们的研究结果表明,建设更多的管道,避免在一些成本最低的盐水储存资源中注入二氧化碳,从而从成本最低的来源捕获二氧化碳是最理想的。©2023化学工业协会和John Wiley &儿子,有限公司

Developing a roadmap for carbon capture, and storage in Oklahoma by assessing the viability of stacked storage

The Intergovernmental Panel on Climate Change concludes that CO2 capture and storage (CCS) is critical for climate-stabilizing energy transitions. In CCS, captured CO2 is sequestered in saline aquifers within sedimentary basins. The CO2 storage capacity and the rate of injection are functions of the geology of the saline aquifer, which is uncertain. To minimize impacts of this uncertainty, CCS projects could include backup plans, such as co-locating geologic CO2 storage (GCS) sites with or near existing CO2-enhanced oil recovery (CO2-EOR) operations. These “stacked storage” projects could hedge against uncertainty in the saline formation performance because captured CO2 could be injected into either location in the event of unexpected events (e.g., the injectivity decreases). Here, we investigate the possibility and ramifications of developing CCS networks in Oklahoma that are amendable to stacked storage. We find that stacked storage is possible in Oklahoma but the counties with the lowest-cost saline storage resources do not have existing CO2-EOR operations. At the systems level, we find it is slightly more expensive (e.g., $1/tCO2 to $5/tCO2) to site GCS in counties with CO2-EOR projects. This increased expense is largely due to increased CO2 transportation costs because hundreds of km of additional pipeline is required to capture CO2 from the lowest-cost sources. Overall, our results suggest that it is optimal to build more pipelines and avoid injecting CO2 in some of the lowest-cost saline storage resources, to enable capturing CO2 from the least-cost sources. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.

期刊介绍: Greenhouse Gases: Science and Technology is a new online-only scientific journal dedicated to the management of greenhouse gases. The journal will focus on methods for carbon capture and storage (CCS), as well as utilization of carbon dioxide (CO2) as a feedstock for fuels and chemicals. GHG will also provide insight into strategies to mitigate emissions of other greenhouse gases. Significant advances will be explored in critical reviews, commentary articles and short communications of broad interest. In addition, the journal will offer analyses of relevant economic and political issues, industry developments and case studies. Greenhouse Gases: Science and Technology is an exciting new online-only journal published as a co-operative venture of the SCI (Society of Chemical Industry) and John Wiley & Sons, Ltd
