Thermodynamic, energy efficiency, and power density analysis of reverse electrodialysis power generation with natural salinity gradients.
Reverse electrodialysis (RED) can harness the Gibbs free energy of mixing when fresh river water flows into the sea for sustainable power generation. In this study, we carry out a thermodynamic and energy efficiency analysis of RED power generation, and assess the membrane power density. First, we present a reversible thermodynamic model for RED and verify that the theoretical maximum extractab...
متن کاملHigh Efficiency in Energy Generation from Salinity Gradients with Reverse Electrodialysis
Renewable energy can be captured from the mixing of salt and fresh water in reverse electrodialysis. This paper investigates the energy efficiency of this process for feed waters that pass a reverse electrodialysis cell once and waters that pass multiple cells or electrode segments. So far, the maximum theoretical energy efficiency was considered to be 50% when the feed waters pass a single cel...
متن کاملReverse Electrodialysis for Salinity Gradient Power Generation: Challenges and Future Perspectives
Salinity gradient energy, which is also known as Blue energy, is a renewable energy form that can be extracted from the mixing of two solutions with different salinities. About 80% of the current global electricity demand could potentially be covered by this energy source. Among several energy extraction technologie...
متن کاملElectric Power Generation with Reverse Electrodialysis
The computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. The program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area S = 1 m × 1 m = 1 m2, cell pair number N = 300 pairs). The stack operatingconditions are optimized. Seaw...
متن کاملModification of Polymeric Membrane for Energy Generation through Salinity Gradient: A Short Review
Salinity gradient energy (SGE) refers to the energy created from the difference in salt concentration between two streams. There are three types of SGE namely, pressure retarded osmosis (PRO), reverse electrodialysis (RED), and capacitive mixing (CapMix). All these technologies require membrane for the system to be operational. In this short review, the membranes modifications for each principl...
