Modeling of power generation from the mixing of simulated saline and freshwater with a reverse electrodialysis system: The effect of monovalent and multivalent ions

Hong, Jin Gi; Zhang, Wen; Luo, Jian; Chen, Yongsheng - In: Applied Energy 110 (2013) C, pp. 244-251

A reverse electrodialysis (RED) system utilizes the transport of cations and anions from controlled mixing of saline water (e.g., seawater) and freshwater (e.g., river water) through selective ion exchange membranes for power generation. Sodium chloride alone has been widely used to create power...
