Progress and prospects in reverse electrodialysis for salinity gradient energy conversion and storage
Ramato Ashu Tufa,Sylwin Pawlowski,Joost Veerman,Karel Bouzek,Enrica Fontananova,Gianluca Di Profio,Svetlozar Velizarov,João G. Crespo,Kitty Nijmeijer,Efrem Curcio +9 more
TL;DR: A critical review of the most significant achievements in RED, focusing on membrane development, stack design, fluid dynamics, process optimization, fouling and potential applications, is presented in this paper, where the main hurdles to market implementation are mainly related to unavailability of high performance, stable and low-cost membrane materials.

Mass transfer in reverse electrodialysis: Flow entrance effects and diffusion boundary layer thickness
TL;DR: In this article, the authors used chronopotentiograms to estimate the diffusion boundary layer thickness in an EDR-Z Mini stack, equipped with Ralex heterogeneous membranes, separated by either sheet flow spacers or mesh-free gaskets.

Computational fluid dynamics (CFD) assisted analysis of profiled membranes performance in reverse electrodialysis
TL;DR: The proposed membrane corrugation design in not limited to the RED application, and could be also extended to other electromembrane processes, such as electrodialysis and Donnan dialysis, in which high ionic mass transport rates are desirable at as low as possible energy costs.

Pressure drop in reverse electrodialysis: Experimental and modeling studies for stacks with variable number of cell pairs
TL;DR: In this paper, a model for the total pressure drop inside a RED stack, with a parallel fluid flow distribution through the compartments, is proposed and experimentally validated for lab-scale RED stacks with sheet flow spacers and compared with an open channel (spacer-free) design.

Improved fluid mixing and power density in reverse electrodialysis stacks with chevron-profiled membranes
Sylwin Pawlowski,Timon Rijnaarts,Michel Saakes,DC Kitty Nijmeijer,DC Kitty Nijmeijer,João G. Crespo,Svetlozar Velizarov +6 more
TL;DR: In this article, the performance of chevron-profiled membranes, prepared by thermal pressing, was experimentally validated in a reverse electrodialysis (RED) stack.
