“…The content of leaf water and root TP in the ‘CO 2 ’ treatment condition was significantly decreased by 3% and 27% compared to the control, respectively (Table ). These results indicated that root absorption of soil water and nutrients was lower in the ‘CO 2 ’ treatment condition, which might lead to changes in the rhizospheric conditions . Meanwhile, the roots in the ‘CO 2 treatment condition’ had 73% and 7% higher starch and TC content compared to the control, respectively (Table ).…”

“…The artificial CO 2 injection was carried out in a greenhouse experimental system established at Kyung Hee University in Geyonggi‐do, South Korea. To inject CO 2 gas into the soils, an acrylic growth box was customized, composed of a set of three flowerpots (30 × 20 × 20 cm, height × width × length) on top of the gas chamber . Each pot had nine holes covered with mesh to disperse the injected CO 2 from the gas chamber to the pots.…”

“…In an extensive review of artificial CO 2 release experiments, most plant metabolic processes, such as photosynthesis, stomatal conductance, and transpiration rate were affected by soil CO 2 concentration higher than 20% . Extremely high soil CO 2 concentration (>40%) caused leaf discoloration and chlorophyll decomposition within one to two weeks, followed by leaf dieback after 15 days . However, in the areas where soil CO 2 concentration ranged from 20–40%, plant responses varied by species .…”

Potential CO2 leakage from carbon capture and storage (CCS) facilities should be monitored and managed carefully. Biomonitoring technologies for CO2 leakage using plants could be very effective, especially in areas near transport pipelines, because of the extensive areas that they can cover. A greenhouse study was conducted to investigate whether early changes in plant parameters could be an effective indicator to detect leaked CO2. Corn (Zea mays), which was reported to be a CO2‐tolerant species, was selected to identify specific indicators of CO2 leakage. The mean soil CO2 concentration for soil treated with CO2 was 20–40%, which is similar to the concentration that could occur near transport pipelines through slow‐insidious seepage. In the soil treated with CO2, the number of yellow leaves at the canopy level was significantly increased from the sixth day of CO2 injection compared to the control. The chlorophyll content in green leaves was significantly reduced on the eighth day from CO2 injection. The soil water content in the treated soil was increased from the sixth day of injection due to reduced root adsorption. The results of this study implied that early changes in parameters of CO2‐tolerant species such as canopy‐level discoloration and chlorophyll content could be used as CO2‐specific indicators for the detection of soil CO2 leakage. We suggested that canopy‐level monitoring is a promising, useful technique for soil CO2 leakage in extensive areas, such as near CO2 transport pipelines. In addition, rhizosphere‐level parameters, such as soil water content, could be good subsidiary indicators together with the large‐scale collection of baseline data and statistical analysis. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

Re-carbonation is investigated using NaOH-dissolved ethanol. Five hundred mL of recycled filtrates is obtained from a previous carbonation in which 3 g of NaOH has been replenished and dissolved. CO 2 is physically absorbed at each re-carbonation, and the amount decreases with increasing numbers of re-carbonation repetitions. However, the amount of CO 2 chemically absorbed that was consumed in the production of precipitates, such as sodium ethyl carbonates (SEC) and NaHCO 3 , slightly increases. This is due to the slight water that accumulates with repeated re-carbonation, which increases the generation of NaHCO 3 and the reaction time. The amount of precipitates and SEC composition decrease from the initial carbonation to the 22nd re-carbonation, and the amount of CO 2 fixed in the precipitates is calculated as a maximum of 0.92 g of CO 2 /g of NaOH at the initial carbonation, which then decreases linearly to 0.56 g of CO 2 /g of NaOH at the 22nd re-carbonation. However, 3.16 g of NaHCO 3 precipitates is repeatedly obtained from the 23rd re-carbonation, maintaining an ethanol concentration of 90.33 wt.%. Thus, 0.55 g of CO 2 /g of NaOH is fixed in this region. Therefore, CO 2 can be fixed in the SEC and NaHCO 3 precipitates via re-carbonation using NaOH-dissolved ethanol.

Plant responses to simulated carbon capture and storage (CCS) CO₂ pipeline leakage: the effect of soil type

Carbon capture and storage (CCS) has been proposed as a bridging technology to enable the transition to an energy system based on renewable sources. Many high CO2‐emitting industries (such as the power industry) are distant from potential carbon storage sites (such as offshore geological reservoirs) and an infrastructure of CO2 transportation must therefore be developed to carry the CO2 to safe storage. As such there is a need to understand the risks involved and the mitigation of potential leaks associated with CCS and dense‐phase CO2 transportation networks. Since 2012 a number of experimental studies have provided a mechanistic understanding of the risks posed to crops as a function of CO2 leakage from CCS infrastructure. However, what remains largely unresolved is the role played by both soil type and soil structure in mitigating and / or enhancing plant stresses. In this study we provide an experimental framework to evaluate these effects. Wheat and beetroot were grown in four different experimental soils to test the effects of specific soil attributes (organic, low pH; organic, open structure; organic, limed; loam, neutral pH) on crop performance when exposed to high levels (∼40%) of CO2 in the soil environment. Comparison between treatment and controls and across the soil types reveals little difference in terms of biomass or plant stress chemistry. From a stakeholder perspective these findings suggest that soil type may play only a minor role in mitigating or amplifying plant stress in response to the unlikely event of a CO2 leak from CCS infrastructure. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
