Salinity Gradient

Capturing energy using salinity gradients where freshwater meets seawater.

Salinity gradient technologies generate electricity from the chemical pressure differential created by differences in ionic concentration between freshwater and saltwater. Seawater has a higher osmotic pressure than freshwater due to its high concentration of salt. Two main technology types, Reverse Electrodialysis (RED) and Pressure-Retarded Osmosis (PRO), make use of semi-permeable membranes which generate an osmotic potential that can be used to generate electricity using turbines in deltas or fjords.
