“…They also compared CCUS marketing content in domestic and foreign newspapers. Their findings suggest that current news coverage of CCUS in China is insufficient due to technical misunderstandings and lack of comprehensiveness [ 38 ]. From the point of current research achievements, the Chinese government on CCUS propaganda dynamics is weak.…”

Carbon capture, utilization and storage (CCUS) has been applied in many countries and has proven to be a key carbon-reduction technology for the future. China currently emits the most carbon, and prior research findings indicate the high potential of CCUS technology to support the country’s emission-reduction process. China introduced CCUS technology at the end of the 20th century and has since implemented a series of related policies. This paper compares the development status of CCUS in China and other countries, studies the legal and policy framework and the development process of CCUS in China, and analyzes the defects in relevant laws and policies. The results show that China’s current legal and policy system is not conducive to the further development of CCUS; specifically, there is no special law, and the policy system is incomplete. Consequently, it is difficult to advance and give full play to the emission-reduction effect of CCUS. To promote CCUS development in China, this paper proposes corresponding countermeasures, including formulating a special law, perfecting the CCUS policy system, expanding government financial support, and improving CCUS public awareness and support.

“…The carbon capture and storage (CCS) technology means the process of separating CO 2 from industrial or related emission sources, transporting it to storage sites, and isolating it from the atmosphere for a long time, which is considered to be the most feasible and immediate way to reduce greenhouse gas emissions and slow down global warming on a large scale in the future. , However, the biggest problem is that the implementation of the CCS project may be costly and require a big budget because no useful products or profits can be created in this process. In more recent years, CO 2 utilization has been included in the CCS concept and a new terminology has been formed, i.e., carbon capture utilization and storage (CCUS). , Injecting CO 2 into the deep coal seams (CO 2 -ECBM) is one of the important ways to realize CO 2 utilization. , It can replace and displace CH 4 to improve the coalbed methane (CBM) recovery efficiency by utilizing the competitive adsorption effect between CO 2 and CH 4 molecules simultaneously; the sequestrated CO 2 in a coal seam can also effectively reduce the carbon emissions. , This technology has attracted lots of attention in China and several CO 2 -ECBM demonstration projects have been developed in Ordos Basin and Qinshui Basin, confirming the effectiveness for raising the CBM production and promoting the CO 2 geological storage …”

To understand and evaluate the CO2 injectivity in different coal seams, low-, middle-, and high-rank coals from Shanxi Province of China were collected to conduct CO2 adsorption/desorption, induced swelling/shrinkage, and permeability experiments. Results show that the adsorption/desorption amount, swelling/shrinkage deformation, and permeability depend on the coal rank. The CO2 adsorption/desorption amount of high-rank coal is the largest, followed by middle-rank coal, and that of low-rank coal is the smallest. The swelling/shrinkage strain and initial permeability of coals follow the sequence middle-rank coal > low-rank coal > high-rank coal. The percentage reductions of permeability of low-rank coal, middle-rank coal, and high-rank coal are 57.46, 48.50, and 71.17% when CO2 adsorption reaches the equilibrium state, indicating that the permeability of high-rank coal is more sensitive for the CO2 adsorption swelling. The swelling and shrinkage deformation presents obvious three-dimensional anisotropic characteristics; the deformation in the vertical bedding plane direction (VBD) is the maximum, the second is that in the parallel face cleat direction (PFD), and the deformation in the parallel butt cleat direction (PBD) is the maximum. The developmental characteristics of cleats and the distribution of macerals in coal contribute largely to the anisotropic deformation of coal induced by CO2 adsorption–desorption. The permeability of coal shows a U-shaped change trend of first decreasing and then increasing after CO2 adsorption because the permeability of coal is first dominated by the CO2 adsorption swelling and then is dominated by the reduction of effective stress. The swelling behavior and permeability attenuation of coal seams after CO2 injection are unavoidable; adopting the reservoir stimulation methods to produce more complex fracture networks is the key to improving CO2 injectivity. Combining the reservoir stimulation methods with CO2-ECBM technology may be an important development direction of the CCUS in coal seams.

“…23−25 In addition, CCS has the potential to reduce CO 2 emissions by 32% by the year 2050. 26 Usually, it has been categorized into three parts: 27 (1) capturing CO 2 emissions from unconventional resources and heavy industries, such as coal plants, oil, and gas, iron, and steel industries; (2) transporting the captured CO 2 to geological formations using pipelines and tankers; and (3) burying or storing permanently to the geological formations CO 2 storage in geological formations is considered to be an effective option to store it permanently and safely. 28 The geological formation used includes deep saline aquifers, depleted oil and gas fields, storage in basalts, storage in coal, deep ocean, and hydrate formation.…”

Carbon capture and storage (CCS) is a climate change mitigation method in which anthropogenic carbon dioxide (CO2) is captured from large point sources and stored in geological formations, in the ocean, or through mineral carbonation. CO2 can be injected and stored for a variety of reasons, including permanent disposal or enhanced oil recovery in certain oil fields. The main objective of this paper is to assess the advances made in CO2 storage projects globally. This study reviews the major companies/businesses that are involved in CCS deployment. The study also presents the alternative for the sequestration of CO2 into the geological formations through existing major projects. It explains their progress, structural and faulting configuration, CO2 transportation and injection, potential CO2 source(s), estimation of the storage capacity, etc. This study also highlights the monitoring programs that are used in different operating projects and the status of active projects. The study suggests that CCS faces further deployment challenges due to the heterogeneity and complexity of rock formations, high cost of deployment, possibility of formation damage during injection and potential for migration and leakage of CO2. Additionally, inappropriate strategy for CO2 injection may lead to wellbore integrity problems, formation of hydrates, and inadequate pressure control. More researchparticularly, geological evaluation before injection and storageis apparently needed.
