Summary: This study examines the feasibility of a novel cryogenic carbon capture method, where CO2 is deposited as frost onto a cold moving bed to continuously remove CO2. Experimental results show that frost front velocities range from 0.4 to 1 mm/s, enabling the design of a moving bed system for continuous capture. Conducted experiments demonstrate successful cryogenic carbon capture under moving bed conditions without frost accumulation.

Summary: This paper investigates the desublimation process of CO2 in a cryogenic turbo-expander and identifies the impact of inlet temperature, pressure ratio, and inlet CO2 concentration on wetness loss. The study concludes that the maximum subcooling degree for a cryogenic carbon capture system turbo-expander should be less than 15 K to avoid desublimation and wetness loss.

Summary: Carbon capture, utilization, and storage (CCUS) technologies, especially cryogenic carbon capture (CCC) methods, are effective in reducing CO2 emissions from fossil fuel power plants by achieving high CO2 recovery and purity. CCC processes can be easily retrofitted and handle gas stream impurities. However, continuous removal of dry ice into storage tanks remains a challenge.

Summary: This paper introduces a novel heat and electricity driven thermoacoustic cooler that uses displacers to replace the resonance tube, improving phase-shifting capability and reducing power dissipation for better cooling performance. Numerical and experimental investigations are conducted to understand the operational characteristics and the impact of operating temperatures on system performance. Experimental results show a record thermal-to-cooling exergy efficiency of 13.4% and cooling power of 117 W, representing a 34% improvement compared to the previous record-holder thermoacoustic cooler.

Summary: In this study, performances of Vuilleumier engine and cooler were investigated using two methods, resulting in the development of the VPBVM model with reasonable results. The relative Carnot efficiencies of the obtained engine and cooler were found to be between 53% to 64% and 43% to 49% respectively at certain conditions. Additionally, the engine's compression ratios could also be obtained, demonstrating the effectiveness of VPBVM for analyzing Vuilleumier machine's engine and cooler.

Summary: This study investigates the use of Electrical Capacitance Tomography (ECT) to monitor real-time CO2 frost formation in a fixed packed bed. The research examines the impact of bed material type and temperature on the evolution of permittivity distribution during the capture process. Results show that ECT can effectively monitor changes in relative permittivity caused by frost formation, demonstrating its potential as a novel technique for monitoring CO2 frost formation during cryogenic carbon capture.

Summary: The use of membranes for CO2 capture is an effective and low-cost technique due to its compact size, energy efficiency, and ease of handling. Hybrid membrane cryogenic (HMC) and low-temperature membrane cryogenic (LTMC) systems combine the advantages of membrane and cryogenic techniques. The performance of the membrane is influenced by permeability, selectivity, and operating temperatures. This review analyzes the costs, energy requirements, and membrane parameters of various HMC and LTMC configurations for CO2 capture.
