Book Part Citation Count: 0Green energy generation using membrane technologies based on salinity gradient(Elsevier, 2023) Güler, Enver; Cihanoğlu,A.; Altıok,E.; Kaya,T.Z.; Eti,M.; Kabay,N.; Chemical EngineeringElectrical energy can be extracted from salinity gradients, often represented by two aqueous solutions with different salinities. This becomes very interesting when sustainable and practical electromembrane processes can be applied to convert the salinity gradient power into electric power. Reverse electrodialysis (RED), in this context, has gained much interest in the last few years. In addition to many operational and design parameters affecting the process output, ion exchange membranes (IEMs) represent core elements in RED. In this chapter, it is aimed to introduce and discuss the current trend of IEMs as well as vital operational parameters and fouling affecting the RED performance. © 2023 Elsevier Inc.

There has been tremendous progress so far in the development of RED process in terms of system development, spacer design, membranes properties and operational conditions optimization. Among those, characteristics of the ion exchange membranes are found to be the critical element affecting the performances of RED process. In this respect, a brief overview of the latest developments in ion exchange membranes were presented in this review, focussing on their properties and performances in RED applications. The recent developments of nanocomposite and ion selective membranes, particularly pore filling ion exchange membranes due to their high performances and inexpensive fabrication cost were also summarized. Shortly, fouling problem for the ion exchange membranes employed in the RED system was mentioned. © 2021 Amirkabir University of Technology - Membrane Processes Research Laboratory.
