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.

盐度梯度发电（SGP）的自由能源生产——两个不同河口的调查结果

摘要

本文的目的是首次利用反向电渗析 (RED) 过程研究 Sebou 河口（摩洛哥）和 Muthupet 河口（印度）这两个选定河流河口因盐度梯度而产生的能源潜力。根据热力学方程估计可用能量。结果表明，当河流流量从 21.93 m ³ s \(^{-1}\) 到 85.67 m ³ s \(^{-1}\)时，两个河口的能源潜力从 12.25 MW 到 430.44 MW 不等。 在河流-河口系统（即Sebou河口）；以及从 0 MW 到 175。河流流量的 15 MW 范围从 0 m ³ s \(^{-1}\) 到 47.63 m ³ s \(^{-1}\) 位于河口泻湖系统（即 Muthupet 河口）。此外，两个河口的河口-河口系统（即Sebou河口）和河口-泻湖系统（即Muthupet河口）的能源潜力可以忽略不计\(<8\)  MW  。
