Summary: Pressure retarded osmosis (PRO) technology utilizes semipermeable membranes to generate electrical energy through a turbine, but has not been fully exploited at commercial scale due to certain drawbacks. This study evaluates the impact of membrane permeability coefficients on energy generation of full-scale single-stage PRO systems. The findings reveal that a decrease in water permeability coefficient results in a significant reduction in energy production, while an increase in solute permeability coefficient has minimal effect at optimal operating points.

Summary: Fouling is a major concern in harvesting salinity gradient energy using reverse electrodialysis (RED). This study focused on developing antifouling membranes by surface modification of a commercial anion exchange membrane with zwitterionic layers. While zwitterionic monomers effectively delayed fouling onset, zwitterionic brushes not only delayed the onset but also slowed down the growth of the fouling layer, leading to higher power density outputs in RED applications.

Summary: The aim of this study was to investigate the negative effects of divalent ions on the power and efficiency of the reverse electrodialysis (RED) process. Two widely shared misconceptions were found, one regarding the role of stack voltage in uphill transport of divalent ions and the other regarding the methodology used to study the effect of divalent ions. The implications of these results suggest the need for more structured research on the effect of divalent ions in membrane processes.

Summary: This study investigates the feasibility of utilizing salinity difference to generate energy in the Strymon River by combining a hydrodynamic model and an SGE model. The results show that the SGE production varies with the salinity difference. A retrospective assessment indicates that the formation of the salt wedge coincides with the period of increased regional electricity demand. In the future, SGE could serve as a decentralized renewable energy source, enhancing energy security in the region.

Summary: Prussian blue analogues are promising electrode materials for desalination systems due to their selective adsorption capacity and low costs. However, their poor conductivity and instability limit their long-term application. This study investigates the co-precipitation process and synthesis strategies to improve the properties of copper hexacyanoferrate powders. Smaller crystallite sizes and lower structural water contents increase the sodium removal capacity but decrease cycling stability. Adding chelators as precursors enhances the material stability.

Summary: This study systematically examined the effects of high ammonia loading on microbial electrolysis cell (MEC) performances. It was found that ammonia loading increased the current but inhibited substrate consumption. The energy recovery efficiency of MECs remained stable, and the electrochemical activity of anode biofilm reached its peak at 1000 mg L-1 ammonia. High ammonia concentration stimulated anode biomass loss and extracellular polymeric substance (EPS) secretion. In acetate-fed MECs, carbon and methane metabolism pathways were inhibited, while in sucrose-fed conditions, glycolysis acted as the rate-limiting step for substrate degradation.

Summary: In this study, a low-cost cathode catalyst based on a NiMo alloy was examined for hydrogen production in microbial electrolysis cells (MECs) as an alternative to noble metals. Two NiMo catalysts were synthesized, one through an electrochemical assisted (NiMo Elec) approach and the other through a hydrothermal (NiMo Ht) approach. The NiMo Ht method showed a higher concentration of Mo atoms in the electrocatalyst compared to the NiMo Elec approach, resulting in a similar current density and minimal overpotential compared to Pt. The high performance and low cost of the NiMo Ht catalyst make it an economically viable approach for biohydrogen generation in MECs.
