Project Status:
How can continuous osmotic power generation in desalination plants be optimized using reverse electrodialysis, and what system-level performance is achievable under real-world operating constraints?
OsmoFlux investigates the feasibility of harvesting usable electrical energy from salinity gradients in desalination brine using reverse electrodialysis (RED). The project combines experimental prototyping with physics-based modeling to study membrane performance, ion transport, and power output across varying salinity and flow conditions. Small-scale RED cells are designed and tested to generate repeatable electrical measurements, which are then used to quantify efficiency trends and inform system-level feasibility for integration into desalination infrastructure. Where experimental limits arise, computational models are developed to extrapolate performance and explore scaling behavior under realistic operating regimes, with ongoing work focused on validating models against experimental measurements
