Integrated carbon capture and utilization (CCU) is appealing for in situ production of fuels and chemicals. Here, we propose and subsequently assess an integrated electrochemical CCU process and compare it with a carbon capture and storage (CCS) route from economic and environmental perspectives. This analysis reveals that under a baseline CCU scenario, carbon products reap either economic (67% and 10% gross margin increase for carbon monoxide [CO] and n-propanol, respectively) or environmental benefits (formic acid production would reduce ∼721 thousand ton carbon dioxide equivalent [CO₂e]/year) relative to the CCS route. Under an optimistic scenario, while all of the carbon dioxide (CO₂)-derived products are economically compelling over the CCS route, only formic acid production would reduce ∼1,465 thousand ton CO₂e/year over CCS (∼575 thousand ton CO₂e/year). This study may serve as a framework to decide whether a CCS or a CCU pathway would be compelling under a given scenario when fuel-cell-based CO₂ capture technology is used to reduce carbon emissions and create economic value from fossil fuel-based power plants.

综合碳捕集与利用（CCU）吸引了就地生产燃料和化学品。在这里，我们提出并随后评估了集成的电化学CCU工艺，并从经济和环境角度将其与碳捕集与封存（CCS）路线进行了比较。该分析表明，在基准CCU情景下，碳产品可带来经济效益（一氧化碳[CO]和正丙醇分别增加67％和10％的毛利率）或环境效益（甲酸生产将减少约721千吨）。二氧化碳当量[CO ₂ e] /年）。在乐观的情况下，同时所有的二氧化碳（CO ₂） -衍生的产品是在CCS路线经济上吸引人，只有甲酸生产将减少~1,465万吨CO ₂ E /年以上CCS（~575万吨CO ₂ E /年）。这项研究可以作为一个框架，以决定当使用基于燃料电池的CO ₂捕集技术减少碳排放并从化石燃料发电厂创造经济价值时，在给定情况下CCS或CCU途径是否具有吸引力。。
