“…Since 2006 the ASGARD site is being used to inject CO 2 gas, initially by the British Geological Survey, UK ) and later by Patil et al (2010) and Sarah andSjogersten, (2009) in 2007-08. Therefore, this chapter while describing the ASGARD site in www.intechopen.com detail presents main findings of previous studies undertaken at this site.…”

“…The remaining 4 plots were left ungassed (control plots). Patil et al (2010) used a total of 16 plots: 8 pasture grass plots and 8 fallow plots which were previously cultivated with agricultural crops, but left untreated for more than 6 months. Pasture and fallow plots were chosen to represent two land use types: perennial pasture grass and fallow land (bare soil).…”

“…To study the effect of CO 2 gassing on soil-inhabiting organisms, earthworm activities were monitored by counting the number of their castings on the surface (Patil et al, 2010). Sarah and Sjogersten (2009) collected soil samples from the turf grass plots from the top 0.1 m depth and at different distance from the center of the plot.…”

“…The top end of the tube was sealed with a plastic on/off valve connectable to a portable GA2000 Landfill Gas Analyzer (Geotechnical Instruments UK Limited) to measure soil CO 2 and O 2 concentrations (in % of total 100% by vol.). In addition, Patil et al (2010) measured soil surface CO 2 efflux from pasture grass and fallow plots (ppm hr −1 ) using Draeger tubes (Draeger Safety AG & Co., Germany,) placed in a grid spacing of 0.5 m × 0.5 m on the surface to monitor gas diffusive pattern within each plot and its horizontal spread. The Draeger tube system is an established method for measuring and detecting contaminants in the soil, water and air.…”

Whereas, Patil et al (2010) collected the soil samples from the top 0.3 m depth, one composite sample from each plot, three times during the gassing period at equal interval, and analyzed for pH and organic matter content. The holes left open after removing augered soil samples were re-filled immediately with local soil and marked to avoid repeated use of the same spots during subsequent sampling periods.…”

Detecting bean stress response to CO₂ leakage with the utilization of leaf and canopy spectral derivative ratio

et al. 2014

Carbon capture and storage (CCS) is one of the critical techniques for mitigating global climate warming which can capture and store the CO2 released during industrial processes into deep geological sites. However, there is a possible risk that the CO2 might leak from under the ground. Therefore, it is important that CO2 leakage spots on the surface of sequestration fields be detected at large scale and on a long‐term basis. The purpose of this study was to design a new model to identify CO2 leakage spots through monitoring the spectral change of vegetation on the surface of the sequestration fields. A field simulation experiment was performed at the Sutton Bonington campus of the University of Nottingham to collect the leaf and canopy reflectance of beans, which grew in soil with different levels of CO2 concentration. Visible symptoms of bean stress caused by CO2 leakage may include the reducing bean vigor and the bean leaves turning yellow. The canopy spectra and leaf spectra were processed by a smoothing, continuum removal and first derivative method. We found that, while the CO2 concentration of the soil increased, the sum of the first derivative reflectance in the 500–550 nm (SDg) increased and that in the 680–760 nm (SDr) decreased gradually compared with that of the control plots. Moreover, the newly developed ratio index SDr/SDg can be effectively used to distinguish gassed and ungassed beans at both leaf and canopy scales. Significant correlation was found between the SPAD values and the SDr/SDg indices (R2 = 0.5687, n = 197). This study indicates that hyperspectral remote sensing techniques can be used to detect CO2 leaking spots by investigating the spectral change of vegetation reflectance in the sequestration fields.

Impacts of CO₂ leakage on plants and microorganisms: A review of results from CO₂ release experiments and storage sites

Carbon capture and storage (CCS) technology, a process consisting of the separation and capture of CO2 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 CO2 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 CO2 release experiments in the field and in greenhouses. In addition, plants and microorganisms were monitored in CO2 storage sites. We review the findings from these studies and suggest directions of future research for determining the impact of potential CO2 leakage from CCS sites on plants and microorganisms. Our review showed that under high levels of soil CO2, (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 CO2 levels and elucidate specific mechanisms underlying these responses. Determining the ecological impacts of geological CO2 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
