Summary: Research on corrosion under supercritical CO2 (s-CO2) conditions is important for the development of Carbon capture, utilization, and storage (CCUS) technology. This work provides an overview of recent progress in this area, highlighting the major corrosion damages and the role of corrosion layers. However, the understanding of corrosion kinetics laws in s-CO2 environments is currently inadequate, and there is a lack of consistency and reliability in reported corrosion outcomes. The review suggests potential research paths to address these gaps and improve the deployment of CCUS technology.

Summary: Large amounts of CO2 from human socioeconomic activities pose a threat to environmental sustainability, worsened by uncontrolled resource use and lack of relevant technology. Carbon capture, utilization, and storage (CCUS) technology has gained global attention as a solution. This article provides a comprehensive analysis for CCUS researchers and policymakers, summarizing innovation trends, technological distribution, and topic evolution. Using bibliometric analysis and data mining methods on 11,915 patent data, the results show that CCUS has entered a rapid development phase since 2013. Patents are mainly distributed in China, the US, and Japan, particularly in heavy industries like energy and electricity. Large enterprises prioritize international patent protection and have a stable network of cooperators. Clustering analysis identified 12 topics, shifting from technicalities to commercialization and encompassing various aspects of daily life.

Summary: This study investigates the economic feasibility of CO2 capture, utilization, and storage (CCUS) technologies in connection to the cement industry. The results show that integrating the production of ethanol, polyols, or food-grade CO2 into the CCUS chain is feasible, but utilization alone is unlikely to be applied. The study also reveals that the cement industry emits more CO2 than can be utilized in a single CO2 utilization plant due to market constraints and limited availability of raw materials.

Summary: Molten alkali metal borates have shown promise as high-temperature sorbents for CO₂ capture. In this work, we used borates to capture CO₂ and enable its electrolytic conversion into multiwalled carbon nanotubes (CNTs) as a sustainable alternative to conventional CNT synthesis techniques. Sodium lithium borate was found to achieve significantly higher CO₂ uptake capacities than alkali metal carbonate salts for CNT synthesis in the 550-650°C range.

Summary: This paper introduces the current development status, research hotspots, challenges, and emerging technologies of carbon capture, utilization, and storage (CCUS) for the problem of global warming and climate change. Solvent absorption technology is the most mature and widely used technology for CO2 capture, and ionic liquid technology has great application prospects. Geological storage, especially in saline aquifers, is currently the most important method for CO2 storage. The challenges faced by CCUS include low capture efficiency, difficulties in transformation and utilization, high operating costs, lack of strong support policies, and lack of international cooperation.

Summary: Supersonic decarburization, a clean CCUS technology using non-equilibrium condensation and swirling separation, is investigated through numerical simulation. The results show that higher pressure, inlet temperature, and mole fraction of CO2 facilitate the condensation process. For separation performance, increasing the mass concentration of inlet heterogeneous droplets improves carbon separation and reduces exergy loss of condensed CO2. This concept has potential applications in offshore natural gas processing for carbon capture.

Summary: This study examines the economic and environmental effects of transitioning towards more circular food systems in the European Union (EU27) by feeding animals with low-opportunity-cost feed and better utilizing local feed resources. The results show that providing subsidies for circularity and promoting the use of low-cost feed can increase animal production, but also have negative impacts on land use and emissions. On the other hand, promoting domestic feed sourcing through import tariffs can decrease animal production and greenhouse gas emissions in agriculture. However, complementary policies are needed to mitigate drawbacks and enhance benefits of a more circular agri-food system.
