Summary: Although membrane distillation is a promising desalination process, it requires a large amount of thermal energy. Studies on combining renewable energy sources with membrane distillation are being conducted to reduce thermal energy consumption. Pilot plant experiments combining solar energy with a membrane distillation system showed that direct contact membrane distillation had a higher water flux compared to air gap membrane distillation. The use of solar energy decreased specific energy consumption and increased the gained output ratio. Therefore, combining solar energy with membrane distillation can improve its performance.

Summary: This study investigates the impact of vacuum enhancement on the performance of multi-envelope AGMD modules under different operating conditions. The results show that vacuum enhancement has the greatest effect on modules with longer residence times and lower hot temperatures. The role of vacuum enhancement in improving vapor diffusion becomes more important with lower driving forces, regardless of feed velocity. Compared to AGMD operation, vacuum enhancement significantly increases the permeate flux, reduces the specific thermal energy consumption, and decreases hydraulic pressure drop.

Summary: The increasing demand for freshwater has led to the development and adoption of desalination technologies. Electrodialysis plays a crucial role in brackish water desalination, but reducing energy consumption is necessary to make it competitive for treating more concentrated solutions like seawater. Exergy analysis is used in this study to determine the contribution of thermodynamic inefficiencies to process efficiency and energy consumption. The results show that factors such as ohmic resistance and undesired transport phenomena significantly affect the efficiency. Improved membranes with low resistances can slightly enhance efficiency. The use of a double-stage configuration greatly reduces energy consumption.

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.
