“…Climate change has become the greatest threat to human civilization in conjunction with the rise in CO 2 emissions. Excess CO 2 and other greenhouse gases in the atmosphere have already warmed the Earth's temperature by around 1.8 • F (1 • C) on average, and even if emissions were to halt immediately, more warming would still occur owing to existing greenhouse gases in the atmosphere [7]. Therefore, concerns about environmental protection prompted the introduction of CO 2 sequestration, which is expanding in conjunction with energy output, as seen in Figure 2.…”

This review focuses on the consequences of the early and rapid deployment of carbon dioxide (CO2) capture and storage (CCS) technologies, which is currently recognized as a critical problem in fulfilling climate change mitigation objectives and as a viable alternative for countries throughout the world. Currently, the geological storage of CO2 is the most effective and, in many cases, the only viable short- to medium-term alternative for considerably moving towards CO2 sequestration in geological sinks and, thus, lowering net carbon emissions into the atmosphere. Furthermore, this review explores the global and environmental measurements of CO2 emissions, as well as the emphasis behind more efficient energy usage. The components of the CCS system are briefly examined, with an emphasis on the technologies that have been developed by previous scholars to support carbon capture, as well as the kinds of carbon geological formations that are suitable sinks for CO2. Additionally, the importance of carbon interaction and sequestration in unconventional formations are examined through case studies that are applied to coalbed seams and shale gas reservoirs. Numerous trapping processes are grouped and introduced in a constructive matrix to easily distinguish the broad trapping mechanisms, which are (1) chemical, (2) physicochemical, and (3) physical trapping, and each of these categories are further classified in depth based on their contribution to CO2 storage.

“…Some countries have been intended to phase down coal utilization as their concrete plans, as widely discussed in [ 15 – 19 ]; however, it is not a practically feasible option in China from near-term perspective: among the total coal consumption in China, nearly 51% of coal is used in coal-fired plants, generating over 70% of annual electricity, which is impossible to be suddenly substituted with the intermittent and random renewable power from energy security consideration [ 12 , 20 , 21 ]; the other 49% of coal is consumed mostly for heating or used as resources in industrial sectors, which could only be changed if there are economically feasible non-fossil substances that can be widely used as alternatives (but it seems impossible at present) [ 20 , 22 ]. Even that carbon capture and storage (CCS) techniques seem to be a promising way to remove those fossil carbon mitigation, they are seldom deployed in an expected scale due to the lower-than-desired efficiency [ 23 ], as well as causing obvious energy efficiency loss and extra expenses. The dilemma of the huge amount of CO 2 emission from fossil consumption and increasing demands of energy in the economic development requires a widespread and urgent transformation and innovations in the energy-related industry.…”

Coal consumption leads to over 15 billion tons of global CO2 emissions annually, which will continue at a considerable intensity in the foreseeable future. To remove the huge amount of CO2, a practically feasible way of direct carbon mitigation, instead of capturing that from dilute tail gases, should be developed; as intended, we developed two innovative supporting technologies, of which the status, strengths, applications, and perspective are discussed in this paper. One is supercritical water gasification-based coal/biomass utilization technology, which orderly converts chemical energy of coal and low-grade heat into hydrogen energy, and can achieve poly-generation of steam, heat, hydrogen, power, pure CO2, and minerals. The other one is the renewables-powered CO2 reduction techniques, which uses CO2 as the resource for carbon-based fuel production. When combining the above two technical loops, one can achieve a full resource utilization and zero CO2 emission, making it a practically feasible way for China and global countries to achieve carbon neutrality while creating substantial domestic benefits of economic growth, competitiveness, well-beings, and new industries.

“…The growing level of global industries and urbanization have inevitably led to the increasing of CO2 emissions to the atmosphere [3]. Thus, an effective and low-cost carbon capture and storage (CCS) approach to remove tons of CO2 gas from the environment is needed to overcome these problems [4]. In recent years, the methods involved in CO2 capture are pre-combustion, post-combustion, and oxy-fuel combustion [5,6].…”

The increase in the concentration of carbon dioxide (CO2) gas in the atmosphere has led to various severe negative consequences. There are numerous methods for the reduction of CO2 that have been introduced such as chemical and physical absorption, organic liquid scrubbing, amine-based absorption, etc. Adsorption by using solid adsorbents is one of the promising methods that has been widely studied by researchers. The performance of the adsorbents can be enhanced by functionalized with diverse types of promoters. This review is discussing the performance of polyethyleneimine (PEI) as a promoter towards the adsorption of CO2. To achieve high effective PEI-adsorbents, the percentage of PEI amine loading, type of porous support, temperature, and different flow conditions are among the important parameters that need to be considered. The chemical stability of PEI can be improved through modification crosslinking of PEI. Hence in this review, the effect of amine loading, porous support, temperature, slow condition and crosslinking of PEI to its CO2 adsorption performance is observed.
