Abstract
Research for renewable energy has grown considerably over the last years. Osmotic energy is a form of renewable energy which is not yet used at commercial scale, but have a large potential to used at commercial scale soon. Osmotic power is a technique that converts the difference of molar free energy between fresh water and salt water into electricity. Pressure retarded osmosis (PRO) is the most frequently studied process of osmotic energy. In PRO two solutions of different salinities are brought into contact by a semipermeable membrane that only allows the transport of water and retain the solute. Positive developments in recent years initiated new studies to the exploitation of osmotic...
Modelling and economic evaluation of pressure-retarded osmosis power plant case study: Iran
, Article International Journal of Ambient Energy ; 2017 , Pages 1-13 ; 01430750 (ISSN) ; Abbaspour, M ; Sharif University of Technology
Abstract
In recent years, a growing interest in investigation of new energies has been observed. Pressure-retarded osmosis (PRO) could be a feasible source of renewable energy. This study aims to present a model based on the present technology of PRO power plant components for design and economic evaluation of a PRO power plant, and to investigate case studies in order to demonstrate how each main component of a PRO power plant affects the economic evaluation. Therefore, all the mechanisms including intake and outfall systems, pre-treatment system, membrane system, and transportation and generation systems are explicated and meant to present the capability of the model to design the PRO power plant....

Abstract
Ion-exchange membrane-based reverse electrodialysis (RED) shows great potential for harvesting osmotic energy from seawater and converting it to electricity. However, their low energy conversion efficiency and huge ionic resistance hinder their application on large scales. The implementation of nanofluidic channels in RED devices can significantly improve the performance of osmotic power generators due to their selective and fast ion transport. However, technical challenges in scalable processing at the nanoscale and ion-selective membranes restrict their development in economically viable generators. Here, we report fibrous-based channels as positively and negatively charged MXene fibers...
