Development frontier and trend prediction on carbon capture technology

Introduction: Carbon capture is a crucial component of CCUS, significantly contributes to emission reduction in high carbon-emitting industries, and serves as a vital technical pathway to attain carbon neutrality.

Method: This study systematically analyzes the development of carbon capture technology through an extensive literature review and patent analysis. High-quality academic papers and patent data from major databases were collected and examined to assess technological trends, status, challenges, and policy influences.

Results: Frontier Trends: Carbon capture technology is advancing from conventional amine methods to innovative approaches like composite solvents, direct air capture (DAC), and electrochemistry. China is at the forefront in patent acquisition and is actively engaged in research and development. Status and Challenges: Despite advancements in second-generation technologies, China faces deficiencies in third-generation technologies, demonstrative applications, and market procedures, with promotion hindered by technological constraints and financial obstacles.

Discussion: In response to the prominent challenges faced by China's carbon capture technology, the following measures can be taken: Enhance strategic planning, achieve advancements in fundamental technologies, establish demonstration clusters, refine investment and financing mechanisms, improve standardization systems, and foster international collaboration and patent strategies.

Conclusion: China possesses a solid basis; nevertheless, it must synchronize policy, technology, and industrial resources to expedite the large-scale implementation of carbon capture and achieve the “double carbon” objective. Development trend: The technology will advance towards “integration + intelligence,” including new materials and artificial intelligence, supported by policies and international collaboration, to facilitate cost-effective commercialization.
