Nanofluidic Membranes to Address the Challenges of Salinity Gradient Power Harvesting
ACS Nano, 2021Salinity gradient power (SGP) has been identified as a promising renewable energy source. Reverse electrodialysis (RED) and pressure retarded osmosis (PRO) are two membrane-based technologies for SGP harvesting. Developing nanopores and nanofluidic membranes with excellent water and/or ion transport properties for applications in those two membrane ...

Salinity gradient power: Optimization of nanopore size
Electrochimica Acta, 2016Abstract Taking account of the effect of diffusioosmotic flow, the salinity gradient power based on reverse electrodialysis is simulated by considering a nanopore connecting two identical, large reservoirs filled with an aqueous sodium chloride solution having different concentrations.

Energy, 1978
Abstract A large source of energy exists at the interface between water bodies of different salinities. Two techniques, pressure-retarded osmosis and reverse electrodialysis, appear to be promising entrees into this energy source. Although the present cost of membranes suitable to these methods is too high, a research and development effort should ...

Salinity‐Gradient Power Generation with Ionized Wood Membranes
Advanced Energy Materials, 2019AbstractReverse electrodialysis (RED) is known as an efficient way of converting the salinity gradient between river water and sea water into energy. However, the high cost and complex fabrication of the necessary ion exchange membranes greatly prohibit the development of the RED process. For the first time, an ionized wood membrane is demonstrated for

Numerical simulation of salinity gradient power generation using reverse electrodialysis
Desalination, 2021Abstract Reverse electrodialysis (RED) is a promising technology that directly converts salinity gradient energy into electrical energy through the directional permeation of ions across the ion exchange membranes (IEMs). Fundamental understanding of the multi-physical RED process requires a reliable description of all the related phenomena involved ...

Salinity-gradient vapor-pressure power conversion
Energy, 1982Abstract The interface between water bodies of different salinities represents a large unexploited source of energy. An energy conversion approach that does not require the use of membranes but uses the differences in vapor pressure between solutions is examined.

Small, 2021
AbstractLarge‐scale salinity gradient power energy harvesting has generated broad attention in recent years, in which affordable ion‐selective membranes (ISMs) are essential for its practical implementation. In this study, for the first time, ISMs derived from natural loofah sponge are reported, which have features of high hydrophilicity, superior ion ...
