Reverse electrodialysis: evaluation of suitable electrode systems [PDF]

Journal of Applied Electrochemistry, 2010
Reverse electrodialysis (RED) is a method for directly extracting electrical energy from salinity gradients, especially from sea and river water. For the commercial implementation of RED, the electrode system is a key component. In this paper, novel electrode systems for RED were compared with existing systems on safety, health, environment, technical ...

Environmentally-safe anion exchange membranes of PVA/PDDA/SiO2composite for reverse electrodialysis

International Journal of Thermofluids, 2023
Anion Exchange Membranes (AEMs) are positively charged polymer membrane used in many applications. In RED systems, AEMs could be used to separate ions to produce energy, and on the other hands remove unwanted molecules in wastewater.
