“…The Zhao-Liao-He (ZLH) method [222] was developed from a model for estimation of storage capacity of the coal bed in the presence of water. The model is based on the CO2 adsorption in the coal bed, CO2 displacement to formation water, and CO2 solubility in water, Eq.…”

Carbon capture and storage (CCS) has been identified as an urgent, strategic and essential approach to reduce anthropogenic CO2 emissions, and mitigate the severe consequences of climate change. CO2 storage is the last step in the CCS chain and can be implemented mainly through oceanic and underground geological sequestration, and mineral carbonation. This review paper aims to provide state-of-the-art developments in CO2 storage. The review initially discussed the potential options for CO2 storage by highlighting the present status, current challenges and uncertainties associated with further deployment of established approaches (such as storage in saline aquifers and depleted oil and gas reservoirs) and feasibility demonstration of relatively newer storage concepts (such as hydrate storage and CO2-based enhanced geothermal systems). The second part of the review outlined the critical criteria that are necessary for storage site selection, including geological, geothermal, geohazards, hydrodynamic, basin maturity, and economic, societal and environmental factors. In the third section, the focus was on identification of CO2 behaviour within the reservoir during and after injection, namely injection-induced seismicity, potential leakage pathways, and long-term containment complexities associated with CO2-brine-rock interaction. In addition, a detailed review on storage capacity estimation methods based on different geological media and trapping mechanisms was provided. Finally, an overview of major CO2 storage projects, including their overall outcomes, were outlined. This review indicates that although CO2 storage is a technically proven strategy, the discussed challenges need to be addressed in order to accelerate the deployment of the technology. In addition, beside the necessity of technoeconomic aspects, public acceptance of CO2 storage plays a central role in technology deployment, and the current ethical mechanisms need to be further improved.

“…Zhao et al [16] proposed an alternative approach to evaluate CO 2 storage capacity in coal beds where formation waters are present. The storage capacity is given by sum of CO 2 adsorption in coal beds, CO 2 solubility in water and CO 2 displacement to formation waters, as follows:…”

“…The CO 2 storage capacity in oil and gas reservoirs in North America were estimated on 33 provinces [6]. China A recent work which was carried out proposed a new estimate of CO 2 storage capacity in coal beds in China [16]. The evaluation has been done considering not only CO 2 adsorption in coal beds but also CO 2 dissolution and displacement to formation water.…”

“…In the evaluation of site suitability for CO 2 storage, the estimation of storage capacity is a critical issue in terms of economic feasibility and safety. Various methods for assessing the CO 2 storage capacities have been applied worldwide [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. However, none of these methodologies have been accepted as a standard one, since they operate at different scales (from country to site-specific), adopting different terminologies, various trapping mechanisms and boundary conditions, rather than showing highly variable and sometimes conflicting results [13].…”

The estimation of CO 2 storage capacity in deep geologic formations is a pre-requisite for an efficient and safe application of Carbon Capture and Storage (CCS). The evaluation of storage resources for CO 2 geological sequestration is a challenging task and has been tackled using several static algorithms and dynamic methods, on a variety of scales ranging from country to site-specific. The purpose of this study is to present an up-to-date as well as an overall review of the storage capacity algorithms for oil and gas reservoirs, coal seams, and deep saline aquifers, including some worldwide estimation examples. Moreover, a practical application at local scale was also performed for an Italian deep reservoir located in the Po Plain (Northern Italy). The effective storage capacities were obtained applying the commonly established static methods, using both the theoretical and the geocellular volume of the reservoir. Although a conservative approach, this study demonstrates that the selected structure has favorable characteristics for CO 2 geological storage and has the capacity to host the most part of the Po Plain CO 2 emissions for several decades.

“…Several aspects need to be considered when it comes to CO2 storage: (i) the storage period should be extensive, preferably hundreds or thousands of years; (ii) the cost of storage, including transport from the place of capture, injection, and monitoring, should be minimized; (iii) the applied methods may not violate any national or international law or regulation; (iv) the environmental impacts need to be carefully considered, and their minimization techniques should be assessed; (v) the probability of occurrence of accidents should be practically null (Zhao et al, 2016). Coal is the sedimentary rock which results from the decomposition of organic matter and is generally found in veins or layers (Maphala and Wagner, 2012).…”

Carbon capture and storage (CCS) has been observed as an alternative measure to mitigate emissions from greenhouse gases. CCS systems separate CO2 during the process of converting fuel and transport to the facilities where they are stored, e.g., under geological formation conditions. Capture and sequestration technologies are now widely used in different industries. CO2 capture is currently a costly and energy-consuming technology. The costs obviously depend on the size of the plant and the type of fuel used. Generally, capture systems are categorized into three categories: pre-combustion, post-combustion, and oxy-fuel combustion. The saline aquifer, depleted oil, and gas fields are large-capacity storage sinks. The coalbeds also provide as a substitute to geological storage. One of the main advantages of coal storage is renewable methane fuel and coal desulfurization. The studied coal reserves are located in Candiota, State of Rio Grande do Sul, Brazil. These are the largest coal deposits in the country, with a reserve of 1 billion tons. This work will represent a study on CO2 storage in Candiota coalbed system. The use of a synthetic CO2 cylinder with a flow of 0.2 L /min varies the time of contact with the coalbed. The results from the volatile matter increase by 11%. The results of the ultimate analysis exhibited an 8% increase for carbon and oxygen after 60 minutes of CO2 flow in the coalbed. On the other hand, there was a reduction of 32% for sulfur. The resultant phenomena occur due to the adsorption capacity of CO2, where the compounds are released from the pores of coal
