Summary: By studying the correlation between membrane and feed stream properties, the researchers proposed critical parameters to describe the representative module properties of the recovery, purity, and process efficiency of CO2. They also found that the process efficiency of the membrane unit was improved in a double-stage configuration, with noticeable improvements in CO2 purity and process efficiency, at a slight expense of CO2 recovery.

Summary: In recent years, the concept of direct CO2 capture and conversion has attracted significant interest due to its potential to address global warming, fossil fuel depletion, and carbon neutral ecosystem. While current CO2 capture technologies are energy intensive and costly, CO2 conversion technologies are still in their early stages with technical challenges to overcome. The emerging high-temperature electrochemical CO2 transport membranes offer a promising approach for capturing and converting CO2 in a single catalytic reactor, with potential for future development.

Summary: The hydrogen economy is gaining increasing attention as a complement to electrification in the global energy transition. This study investigates the techno-economic potential of hydrogen production from large-scale coal/biomass co-gasification plants with CO2 capture, achieving attractive hydrogen production costs with the use of advanced configurations. Gasification of locally available solid fuels should be seriously considered as a viable option for supplying the emerging hydrogen economy alongside natural gas and electrolysis.

Summary: To produce hydrogen with low CO concentration, steam methane reforming was conducted in a Pd membrane reactor containing a methanation catalyst on the permeation side. By using a two-step vacuum-assisted electroless plating method, hydrogen selectivity was increased significantly and CO concentration was reduced to 200 ppm, making it suitable for use in LT-PEMFCs. Introducing a methanation catalyst on the permeation side further lowered the CO concentration to 4 ppm in the permeate stream, with 97.7% H2 content, which is ideal for LT-PEMFCs.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
