What Are the Likely Air Pollution Impacts of Carbon Capture and Storage?
量化了美国墨西哥湾地区碳捕集、利用与封存（CCUS）对当地空气污染的影响，发现CCUS会增加氨排放，导致天然气电厂和多数工业设施的空气污染损害净增加，表明CCUS在全球气候效益与当地社区成本之间存在显著权衡。
We quantify the potential impacts of carbon capture, utilization, and storage (CCUS) on local air pollution in the US Gulf region. We characterize pre-CCUS local air pollution emissions from fossil-fuel electricity generation and large industrial carbon emitters and compare these with projected post-CCUS local air pollution emissions, leveraging carbon capture quotient estimates from the engineering literature. We then analyze net emissions impacts on secondary particulate matter formation and damages via the AP3 integrated air pollution assessment model. An important aspect of the environmental impact of CCUS is increased ammonia emissions from CCUS technology, which we show can lead to net air pollution damages from CCUS deployment at natural gas power plants and most industrial facilities. Taken as a whole, our work suggests that CCUS may pose significant trade-offs between global climate benefits and costs to local communities.
