Engineered PES/SPES nanochannel membrane for salinity gradient power generation
Nano Energy, 2019Abstract Nature is the source of human being's creativity and always inspires people to break through the existing bottleneck of science and technology. Electric eel (Electrophorus electricus) relying on ion channel in electrocyte can convert salinity gradient energy to electricity power with potentials of ~600 V to stun prey and ward off predators ...

Recent development in salinity gradient power
Oceans 2003. Celebrating the Past ... Teaming Toward the Future (IEEE Cat. No.03CH37492), 2003An often-overlooked source of marine renewable energy is the energy available from salinity gradients. The potential resource for the osmotic pairing of fresh water and seawater is estimated at 2.6 TW. Several concepts have been proposed. Obviously, any scheme to desalinate seawater can be operated in reverse.

Anomalous pH‐Dependent Nanofluidic Salinity Gradient Power
Small, 2017AbstractPrevious studies on nanofluidic salinity gradient power (NSGP), where energy associated with the salinity gradient can be harvested with ion‐selective nanopores, all suggest that nanofluidic devices having higher surface charge density should have higher performance, including osmotic power and conversion efficiency.

Salinity Gradient Power: Utilizing Vapor Pressure Differences
Science, 1979By utilizing the vapor pressure difference between high-salinity and low-salinity water, one can obtain power from the gradients of salinity. This scheme eliminates the major problems associated with conversion methods in which membranes are used. The method we tested gave higher conversion efficiencies than membrane methods.

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 ...
