Salinity Gradient Energy at River Mouths

Environmental Science & Technology Letters, 2014
River mouths are potentially abundant locations for the exploitation of the clean and renewable salinity gradient energy (SGE) as here perpetually fresh water mixes with saline seawater. However, the practical yield of SGE depends on the spatiotemporal variability of the salinity structure.

Paper-based energy harvesting from salinity gradients

Lab on a Chip, 2016
Environment-friendly and flexible paper-based energy harvesting with a simple configuration is proposed using the principle of reverse electrodialysis (RED). Owing to the intrinsic capillary flow in paper, a pump-less and truly portable paper based power source is realized and it can be integrated directly with μPADs as a practical application.

Energy from Salinity Gradients

ECS Meeting Abstracts, 2017
Osmotic power or salinity gradient power (SGP) is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO).

Salinity gradient energy

2010
There exists a huge potential for the generation of energy from the mixing of saltwater and freshwater. The potential is 2.6 TW, which is more than the global electricity consumption (2.0 TW). Two membrane-based technologies exist to convert this potentially available energy into useful power: pressure-retarded osmosis (PRO) and reverse electrodialysis

Surveying Manganese Oxides as Electrode Materials for Harnessing Salinity Gradient Energy

Environmental Science & Technology, 2020
The potential energy contained in the controlled mixing of waters with different salt concentrations (i.e., salinity gradient energy) can theoretically provide a substantial fraction of the global electrical demand. One method for generating electricity from salinity gradients is to use electrode-based reactions in electrochemical cells.

Exergy Analysis-Potential of Salinity Gradient Energy Source

Journal of Energy Resources Technology, 2018
Mixing of fresh (river) water and salty water (seawater or saline brine) in a controlled environment produces an electrical energy known as salinity gradient energy (SGE). Two main conversion technologies of SGE are membrane-based processes: pressure retarded osmosis (PRO) and reverse electrodialysis (RED).
