Abstract: Salinity gradient energy presents a promising opportunity for renewable energy, gaining significant interest in the sustainable power sector. This article presents an overview of the application of ion exchange membranes and reverse electrodialysis techniques to harness energy from salinity gradients in seawater, employing anthropomorphic terminology to enhance understanding. The main focus lies in the utilization of ion exchange membrane technology for power generation, with a particular emphasis on its current implementation status and underlying operational principles. The research aims to enhance readers’ comprehension of salinity gradient energy in seawater and promote awareness of “energy security” through the use of descriptive language.

Key words: Salinity gradient energy, Ion exchange membrane, Reverse electrodialysis
