“…Although previous studies consistently reported that plants exposed to high soil CO 2 showed inhibited growth (Patil, Colls & Steven, 2010; Al-Traboulsi et al, 2013; Zhao et al, 2017), few clearly identified the main driving factor of these negative impacts (Pfanz et al, 2004; Pfanz & Saßmannshausen, 2008; He et al, 2016). Beaubien et al (2008) and Stephens & Hering (2002) observed that water absorption of plants was lower, but they did not distinguish the effects of high soil CO 2 (∼100% at 20 cm depth) from those of low O 2 or other trace gases such as H 2 S and CH 4 .…”

To ensure the safety of carbon capture and storage (CCS) technology, insight into the potential impacts of CO2 leakage on the ecosystem is necessary. We conducted a greenhouse experiment to investigate the effects of high soil CO2 on plant growth and the soil environment. Treatments comprised 99.99% CO2 injection (CG), 99.99% N2injection (NG), and no injection (BG). NG treatment was employed to differentiate the effects of O2 depletion from those of CO2 enrichment. Soil CO2 and O2 concentrations were maintained at an average of 53% and 11%, respectively, under CG treatment. We verified that high soil CO2 had negative effects on root water absorption, chlorophyll, starch content and total biomass. Soil microbial acid phosphatase activity was affected by CG treatment. These negative effects were attributed to high soil CO2 instead of low O2 or low pH. Our results indicate that high soil CO2 affected the root system, which in turn triggered further changes in aboveground plant tissues and rhizospheric soil water conditions. A conceptual diagram of CO2 toxicity to plants and soil is suggested to act as a useful guideline for impact assessment of CCS technology.

“…For example, this was demonstrated at the ASGARD (Artificial Soil Gassing and Response Detection) facility site, where injected CO 2 significantly limited productivity in both grass and clover, visible stress symptoms were observed in plants exposed to high soil CO 2 concentrations, and the spectral reflectance also changed [12,13]. This has also been shown in Korea, where a medium CO 2 treatment (i.e., with a soil CO 2 concentration of 12%) retarded plant germination, and no seeds germinated with a high CO 2 concentration (29.4%) [14]. Many assessments of the effects on plants due to CO 2 leakage have mostly focused on plant responses.…”

To assess the environmental risks of carbon capture and storage (CCS) due to underground CO2 leakage, many studies have examined the impact on plant growth; however, the effect of leaked CO2 on root morphology remains poorly understood. This study simulated the effects of CO2 leakage from CCS on maize (Zea mays L.) root systems through pot experiments—one control treatment (no added CO2) and two elevated soil CO2 treatments (1000 g m−2 d−1 and 2000 g m−2 d−1). Compared with the control, root length, root surface area, and root volume were reduced by 44.73%, 34.14%, and 19.16%, respectively, in response to CO2 treatments with a flux of 2000 g m−2 d−1. Meanwhile, the fine root length in CO2 treatments with a flux of 1000 g m−2 d−1 and 2000 g m−2 d−1 were reduced by 29.44% and 45.88%, respectively, whereas no obvious difference in regard to coarse roots was found. Understanding changes in plant root morphology in this experiment, especially the decrease in the fine root length, are essential for explaining plant responses to CO2 leakage from CCS.

“…The photosynthetic parameters of Pn, Gs, and Tr and transmittance parameters of chlorophyll content had limited field applicability because these parameters were only measured at the leaf level, although the measurements would not destroy plants (Wu et al, 2014;Kim et al, 2017). Finally, biomass measurement destroyed plants and could not be remotely, automatically, and continuously detected, which had the lowest field applicability (He et al, 2016) (Table 6). Delegido et al (2011), Gautam et al (2015, Kim et al (2019), Male et al (2010), Penuelas et al (1997), Ryu et al (2014) Although the range of the device prices is large and there could be cheap sensors that are not commercially manufactured, we took the median price for simplicity (the median value between the lowest and highest prices) to evaluate and compare the cost of sensors.…”

Vegetation monitoring can be used to detect CO2 leakage in carbon capture and storage (CCS) sites because it can monitor a large area at a relatively low cost. However, a rapidly responsive, sensitive, and cost-effective plant parameters must be suggested for vegetation monitoring to be practically utilized as a CCS management strategy. To screen the proper plant parameters for leakage monitoring, a greenhouse experiment was conducted by exposing kale (Brassica oleracea var. viridis), a sensitive plant, to 10%, 20%, and 40% soil CO2 concentrations. Water and water with CO2 stress treatments were also introduced to examine the parameters differentiating CO2 stress from water stresses. We tested the hypothesis that chlorophyl fluorescence parameters would be early and sensitive indicator to detect CO2 leakage. The results showed that the fluorescence parameters of effective quantum yield of photosystem II (Y(II)), detected the difference between CO2 treatments and control earlier than any other parameters, such as chlorophyl content, hyperspectral vegetation indices, and biomass. For systematic comparison among many parameters, we proposed an indicator evaluation score (IES) method based on four categories: CO2 specificity, early detection, field applicability, and cost. The IES results showed that fluorescence parameters (Y(II)) had the highest IES scores, and the parameters from spectral sensors (380–800 nm wavelength) had the second highest values. We suggest the IES system as a useful tool for evaluating new parameters in vegetation monitoring.
