  • Published:
Journal of Engineering Thermophysics Aims and scope

Abstract

The purpose of this paper is to investigate the energy potential due to salinity gradient of the two selected river estuaries, i.e., Sebou-estuary (Morocco) and Muthupet-estuary (India) for first time using Reverse Electro-Dialysis (RED) process to estimate the available energy, based on thermodynamic equations. The results showed that the energy potential for both estuaries varies from 12.25 MW to 430.44 MW for a river discharge ranges from 21.93 m3s\(^{-1}\) to 85.67 m3s\(^{-1}\) in River-Estuarine system (i.e., Sebou estuary); and from 0 MW to 175. 15 MW for a river discharge ranges from 0 m3s\(^{-1}\) to 47.63 m3s\(^{-1}\) in Mouth-Lagoon system (i.e., Muthupet-estuary). In addition, the energy potential at Mouth-Estuarine system (i.e., Sebou-estuary) and Mouth-Lagoon system (i.e., Muthupet estuary) for both estuaries is negligible \(<8\) MW.
