Summary: In order to fulfill the Paris Agreement, CO2 capture technologies must be developed to reduce Green House Gas emissions. Adsorption is considered a viable technology due to its mild conditions. Selective sorbents with high CO2 adsorption capacities are needed. This study used branched poly-ethylenimines (PEI) with different average molecular weights, agglomerated with silica at different weight percentages. Adsorption was measured and kinetic parameters were estimated. The results showed that the materials produced were selective and had potential use in adsorption processes, with the sample of the lowest average molecular weight having the highest adsorption capacity.

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 article provides a comprehensive review on the importance of carbon capture and storage (CCS) in combating global warming. It critically summarizes the characteristics and performances of liquid-based, solid-based, and microencapsulated carbon capture materials, as well as in situ and ex situ mineral storages. Possible solutions to improve CO2 capture capacity and progress in CO2 capture and mineral storage are proposed. The applications of CCS in post-combustion CO2 capture and mineral storage are systematically compared. This work contributes to a better understanding of the current state and future trends of CCS and plays a significant role in advancing basic research and commercial applications.

Summary: A new methodology for evaluating commercial adsorbents for CO2 capture using temperature swing adsorption has been developed. The study found that binderless zeolites performed better in CO2 production and desorption energy compared to their binder-based counterparts. The 13XBL binderless zeolite had the highest CO2 production and lowest desorption energy, while the 5A zeolites had the lowest CO2 production and highest desorption energy among the zeolites.

Summary: The study demonstrates that impurities in CO2 streams can have an impact on enhanced oil recovery and carbon capture and storage performance. Different types and concentrations of impurities affect the maximum miscibility pressure (MMP) of the oil-gas mixture, leading to decreased displacement efficiency and reduced oil density.

Summary: This study examines the independent and concomitant role of temperature and pressure in determining CO2 mass transport and selectivity in biogas upgrading. The results show that pressurisation is crucial for enhancing CO2 flux and selectivity when microporous or nonporous membranes are used. This process intensification reduces energy consumption and methane losses, making it a competitive solution for biogas upgrading.

Summary: Absorption-based separation processes are crucial for deep decarbonisation, but the anticipated cost reduction has not been achieved. Previous research focused on developing novel aqueous blends of amines, which failed to address the issue of high water content in solvents. This study presents a thought-experiment using a hypothetical solvent to determine the limit of cost reduction.

Summary: This paper evaluates the opportunities for CO2 capture and storage within a 1,000 km radius of Singapore. The results show significant CO2 emissions in the study area, as well as substantial storage resources in oil reservoirs, gas reservoirs, and saline aquifers. The paper also proposes an ASEAN CCS corridor to transport captured CO2 from Singapore and host countries for permanent storage in these basins.

Summary: Representative low-cost materials were embedded in mortar to mimic the casing-mortar interface in injection wells. Two types of cement were investigated for their corrosion resistance, and exposure tests revealed unexpected corrosion types on steel surfaces. Surface analysis and element mapping were used to trace chloride intrusion and corrosion process on exposed specimens.

Summary: This paper assesses the impact of decarbonization on the energy system and related employment in South Africa, showing how the increase in renewable energy sources can partially offset the decline in coal-related jobs. A transition from coal to renewable energy requires comprehensive plans, policy formulations, support mechanisms, and structural transformation to mitigate employment impacts and ensure a just transition.

Summary: By juxtaposing China's current situation and policies toward coal and renewables at home and abroad, this article argues that China is in a paradoxical state of carbon lock-in. It analyzes the multiple factors that contribute to China's coal-related policies and draws four major conclusions. The study suggests that China should promote disruption rather than incumbency, strengthen renewable energy advocates throughout all levels of government, and consider building alternative cleaner projects while halting the ones in progress.
