Abstract

Carbon capture and storage (CCS) technology, a process consisting of the separation and capture of CO 2 from point sources and injection into deep geological reservoirs for long‐term isolation from the atmosphere, is considered to be a promising technology that can mitigate global climate change. However, the risk of CO 2 leakage from storage sites exists, and thus its impact on ecosystem functions needs to be understood for safe implementation of CCS. Plant and microbial parameters were monitored in artificial CO 2 release experiments in the field and in greenhouses. In addition, plants and microorganisms were monitored in CO 2 storage sites. We review the findings from these studies and suggest directions of future research for determining the impact of potential CO 2 leakage from CCS sites on plants and microorganisms. Our review showed that under high levels of soil CO 2 , (i) plant stress response was visible within short period of time; (ii) dicots were more sensitive than monocots in most studies; and (iii) the responses of microorganisms were more diverse and harder to generalize than those of plants. Only a limited number of field and greenhouse experimental studies have been conducted so far, and thus more field and greenhouse experimental studies are needed to better understand the plant and microbial response to elevated soil CO 2 levels and elucidate specific mechanisms underlying these responses. Determining the ecological impacts of geological CO 2 storage and ensuring its environmental safety via such research will make CCS a more viable technology. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd
