Summary: In this study, a hybrid process combining hydrate based separation, membrane separation, and amine-absorption separation technologies was designed for CO2/H-2 mixture separation. The results showed that the combination of hydrate formation separation technique with membrane separation technology resulted in a CO2 capture process with the lowest energy consumption and total cost per unit weight of captured CO2. The best scheme for hybrid hydrate CO2 capture process was the hybrid hydrate-membrane process in the presence of TBAB as hydrate promoter, with a total cost of 29.47 US$/ton CO2.

Summary: To understand the impact of intermittent operation of a power plant using amine-based carbon capture processes, stress tests were conducted on a plant operating with a mixture of two amines. A machine learning model was developed to forecast emissions and model the impact of interventions. The findings suggest the need for reconsidering mitigation strategies for capture plants using a mixture of amines, as certain interventions have opposite effects on the emissions of solvent components.

Summary: Power-to-Liquid plants are important for future energy systems and require economic evaluations to assess their competitiveness. A techno-economic assessment was performed on a green methanol plant concept, considering different scenarios. The study found that green methanol prices, CO2 prices, and hybrid power plant design are crucial factors for economic performance. The concept offers a solution to the major drawbacks of Power-to-Liquid plants and establishes stable long-term scenarios for interested investors.

Summary: This study presents a scale-up design, scheduling, and costing of a single-stage MOF-based 5-step temperature swing adsorption (TSA) process for carbon capture and concentration (CCC) from wet flue gas without pre-drying. The TSA process is compared with a two-stage process at two feed conditions, where the wet flue gas is first dried in a TSA process and then CCC is carried out in a MOF-based 6-step vacuum swing adsorption (VSA) process. The two-stage process has lower minimum capture costs at both feed conditions.

Summary: In this study, a framework for CO2 capture and utilization for energy products (CCU4E) was developed and examined for its techno-economic and environmental performance. A total of 72 CO2-to-fuel pathways were analyzed to understand the trade-off between economic output and environmental impact, with a focus on the role of H2 in mitigating CO2eq emissions and economic potential. The study also highlighted the significance of green hydrogen price as a key factor in future CCU4E for reducing CO2eq emissions at a more stable and lower cost.
