Salinity gradient heat engines: An innovative concept for waste heat valorization

Modeling, Simulation, and Optimization of Membrane Processes

“…Highlighted in this Special Issue is the use of specialized membranes that impact the energy production. Membrane research in the energy sector has used the concept of salinity gradient exchange (SGE), utilizing the chemical potential between waters of differing salinity levels [8]. The difference in salinity levels causes water to move across semipermeable membranes via the principles of osmosis where the energy is harvested using the pressurized water from the osmotic movement which can spin turbines to generate energy.…”
