Advancing “Carbon Peak” and “Carbon Neutrality” in China: A Comprehensive Review of Current Global Research on Carbon Capture, Utilization, and Storage Technology and Its Implications

Abstract

Carbon capture, utilization, and storage (CCUS) technology plays a pivotal role in China's "Carbon Peak" and "Carbon Neutrality" goals. This approach offers low-carbon, zero-carbon, and even negative-carbon solutions. This paper employs bibliometric analysis using the Web of Science to comprehensively review global CCUS progress and discuss future development prospects in China. The findings underscore it as a prominent research focus, attracting scholars from both domestic and international arenas. China notably leads the global landscape in terms of research paper output, with the Chinese Academy of Sciences holding a prominent position in total published papers. The research predominantly centers on refining geological storage techniques and optimizing oil and gas recovery rates. Among the CCUS pathways, enhanced oil recovery technology stands out due to its relative maturity and commercial applicability, particularly within the conventional oil and gas reservoirs. The application potential of enhanced gas recovery technology, especially in the Sichuan and Ordos Basins in China, necessitates robust research and demonstration efforts. Within China's current energy landscape, "Blue Hydrogen" emerges as the primary solution for hydrogen production in conjunction with CCUS technology. The underground coal gasification approach holds significant promise as a hydrogen production avenue, albeit with inherent ecological and environmental challenges tied to geological storage that require meticulous consideration. The establishment of effective risk identification and evaluation methodologies for geological storage is imperative. The trajectory ahead involves a strategic convergence of policy, technology, and market dynamics to enhance China's CCUS policy framework, legislative framework, standardization initiatives, and pioneering technological advancements. These collective efforts converge to outline an exclusive development pathway in China. This study assumes a pivotal role in accelerating CCUS technology research and deployment, enhancing oil and gas recovery efficiency, and ultimately realizing the overarching goals of a "Dual Carbon" future.

Production of Coal Fines in Deep Coal Seam via Morphologic, Flow-Channel, Mineral Analyses: Evidence from Coalbed Methane Wells in the Qinshui Basin

“…The exploitation of coalbed methane (CBM) in China carries the triple advantage of promoting environmental conservation, enhancing safety in coal mining operations, and augmenting the supply of clean energy. With the nation’s CBM reserves ranking third globally, the strategic development of these resources is crucial for China’s ambitions toward peak carbon emissions and carbon neutrality. − A depth of 1000 m serves as the demarcation between deep and shallow coal seams, based on evaluations and exploratory initiatives within the country . China’s deep CBM resources, situated between 1000 and 1500 m and between 1500 and 3000 m, are estimated at approximately 21 × 10 12 and 30 × 10 12 m 3 , representing 38.2 and 54.5% of total reserves, respectively.…”
