Summary: Power to gas (PTG) technology converts power into energy-storage gas, absorbing excess power and releasing it when needed. Based on CO2 emissions in Karamay City, China, this study designed a process flow for CO2 absorption and hydrogen and CO2 methanation in PTG technology. The results show high efficiencies in the absorption (91.5%) and methanation (77.5%) processes, with 17.85 MW heat recovered. The cost of producing synthetic natural gas (SNG) in the PTG factory is 1782 USD/ton. Although the current contribution to carbon emissions reduction is small, PTG technology is expected to play a significant role in achieving carbon-emission-reduction targets in the future as technology advances and the carbon trading market improves.

Summary: Pressure-swing adsorption (PSA) is gaining popularity as a CO2 capture process due to its efficiency, low cost, and environmental friendliness. This study focuses on the synthesis of a unique sunflower-shaped superstructure of CHA zeolite with high adsorption selectivity and improved mass transfer rate and diffusion. The resulting hierarchical superstructure demonstrated a significantly higher CO2 uptake and ultrahigh separation selectivity, making it a promising candidate for CO2 capture via the PSA process.

Summary: This work presents a kinetic study of CO2 capture on Na2ZrO3 as a function of temperature and CO2 flow rate. A new kinetic model is proposed and discussed, which considers the formation of a Na2CO3-ZrO2 layer and the enhancement of the capture process by Na+ ions diffusion. The results show that the CO2 capture efficiency is improved as the CO2 flow rate increases. The activated state energy for surface capture and bulk capture are calculated using the Eyring model. The study also discusses the impact of CO2 sorption desorption process at low temperature and flow rate on high-temperature CO2 capture.

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.

Summary: This study proposes a new concept for the separation of CO2 from the offshore natural gas industry by utilizing the phase change behavior in supersonic flows, which combines the effects of nonequilibrium condensation and swirling flow separation. The feasibility of this concept is evaluated using computational fluid dynamics modeling, and the results show that the supersonic flow can condense 28% of CO2 in a liquid state from the main gas flow.
