In a closed system, reverse electrodialysis (RED) and electrodialysis (ED) can be coupled into an energy storage system where excess power can be placed in a salinity gradient between two solutions. The device is powered by applying an external power source to force ions from a dilute solution to a concentrated solution through alternating ion exchange

Reverse electrodialysis: A validated process model for design and optimization
Chemical Engineering Journal, 2011Reverse electrodialysis (RED) is a technology to generate electricity using the entropy of the mixing of sea and river water. A model is made of the RED process and validated experimentally. The model is used to design and optimize the RED process. It predicts very small differences between counter- and co-current operation.It was decided to focus on ...

Reverse electrodialysis for emerging applications
Bulletin of the Korean Chemical Society, 2022AbstractReverse electrodialysis (RED) is an eco‐friendly power generation system that produces electricity from the salinity difference between two solutions of different concentrations. Recently, research on RED has expanded not only to increase the maximum power density, but also to converge with other energy generation systems.

Reclaiming reverse osmosis blowdown with electrodialysis reversal
Desalination, 1990Abstract The installation of EDR for reclaiming RO blowdowns, to reduce feedwater supply requirements to RO in water short areas, and EDR's reduction of waste brine volumes to evaporative ponding has been an unconditional success. The data, and the successful performance from this installation, has already generated additional applications for EDR ...

Renewable energy by reverse electrodialysis
Desalination, 2007The use of reverse electrodialysis (RED) to derive energy from the difference between the chemical potentials of concentrated and diluted salt solutions was examined. The process employs the flows of brine and dilute solutions through alternating cells determined by cation- and anion-exchange membranes in a stack placed between two electrodes to ...

Chapter 2 Electrodialysis Reversal
2007Publisher Summary This chapter provides an overview of technology of electrodialysis reversal (EDR). The ion flux across the membrane is influenced by the boundary layer formed at the membrane/solution interface. The boundary layer thickness is a function of velocity and flow spacer geometry, and it is minimized by promoting turbulent flow, and thus ...
