“…The adsorption capacity of CO 2 in coal is better than that of CH 4 in high-temperature and pressure environment (Andreas and Yves 2011). Therefore, when CO 2 is injected and adsorbed on a matrix in coal, it can improve not only the CO 2 storage capacity, but also the CH 4 output (Pratama et al 2018).…”

The technology used to enhance coalbed methane (CBM) recovery by injecting CO 2 (CO 2-ECBM) with heat, combining heat injection with CO 2 injection, is still in its infancy; therefore, theoretical studies of this CO 2-ECBM technology should be perused. First, the coupling equations of the diffusion-adsorption-seepage-heat transfer fields of gas are established. The displacement processes under different pressures and temperatures are simulated by COMSOL. Finally, the displacement effects, a comparison of the CO 2 storage capacity with the CH 4 output and the effective influencing radius of CO 2 injection are analyzed and discussed. The results show that (1) the displacement pressure and temperature are two key factors influencing the CH 4 output and the CO 2 storage capacity, and the increase in the CO 2 storage capacity is more sensitive to temperature and pressure than the CH 4 output. (2) The gas flow direction is from the injection hole to the discharge hole during the displacement process, and the regions with high velocity are concentrated at the injection hole and the discharge hole. (3) A reduction in the CH 4 concentration and an increase in the CO 2 concentration are obvious during the displacement process. (4) The effective influencing radius of injecting CO 2 with heat increases with the increase in time and pressure. The relationship between the effective influencing radius and the injection time of CO 2 has a power exponential function, and there is a linear relationship between the functional coefficient and the injection pressure of CO 2. This numerical simulation study on enhancing CBM recovery by injecting CO 2 with heat can further promote the implementation of CO 2-ECBM project in deep coal seams.

“…They are abundant and have the potential to store much more CO 2 than oil and gas reservoirs. However, they are often located at greater depths and require additional drilling and injection technologies. − Unmineable coal seams, which are also abundant, can be used for CO 2 storage and enhanced methane recovery, which provides an additional economic incentive for CCS. ,− …”

This Review provides an in-depth overview of carbon dioxide (CO 2 ) capture, utilization, and sequestration (CCUS) technologies and their potential in global decarbonization efforts. The Review discusses the concept of CO 2 utilization, including conversion to fuels, chemicals, and minerals as well as biological processes. It also explores the different types of CO 2 sequestration, including geological, ocean, and mineral storage, and the associated challenges and opportunities such as regulatory issues and public acceptance. The Review highlights the potential of integrating CO 2 CCUS technologies and presents case studies of successful projects. The benefits and limitations of these technologies are discussed, along with areas for further research and development. Overall, this Review underscores the importance of CCUS.

“…CO 2 displacement can be adopted for CBM recovery [9]. CO 2 -enhanced coalbed methane (CO 2 -ECBM) technology involves the injection of CO 2 into a coal seam rich in CBM, to sequester CH 4 , promotes clean green energy, and is widely used in the production of deep ultra-low permeability coal seams [10][11][12][13][14].…”

The injection of CO2 to displace CH4 in coal seams is an effective method to exploit coalbed methane (CBM), for which the CO2 injection temperature and pressure are important influential factors. We performed simulations, using COMSOL Multiphysics to determine the effect of CO2 injection temperature and pressure on CO2-enhanced coalbed methane (CO2-ECBM) recovery, according to adsorption/desorption, seepage, and diffusion of binary gas (CO2 and CH4) in the coal seam, and deriver a thermal–hydraulic–mechanical coupling equation of CO2-ECBM. The simulation results show that, as CO2 injection pressure in CO2-ECBM increases, the molar concentration and displacement time of CH4 in the coal seam significantly decrease. With increasing injection temperature, the binary gas adsorption capacity in the coal seam decreases, and CO2 reserves and CH4 production decrease. High temperatures are therefore not conducive for CH4 production.
