1. Reversed electrodialysis

   Reverse electrodialysis (RED) is the salinity gradient energy retrieved from the difference in the salt concentration between seawater and river water. A method of utilizing the energy produced by this process by means of a heat engine was invented by Prof. Sidney Loeb in 1977 at the Ben-Gurion University of the Negev. --United States Patent US4171409 In reverse electrodialysis a salt solution and fresh water are let through a stack of alternating cation and anion exchange membranes. The chemical potential difference between salt and fresh water generates a voltage over each membrane and the total potential of the system is the sum of the potential differences over all membranes. The process works through difference in ion concentration instead of an electric field, which has implications for the type of membrane needed.In RED, as in a fuel cell, the cells are stacked. A module with a capacity of 250 kW has the size of a shipping container. In the Netherlands, for example, more than 3,300 m3 fresh water runs into the sea per second on average. The membrane halves the pressure differences which results in a water column of approximately 135 meters. The energy potential is therefore e=mgΔh=3.3*106 kg/s*10 m/s2*135 meters ca.= 4.5*109 Joule per second, Power=4.5 gigawatts.

1. Reversed electrodialysis

   Reversed electrodialysis is the salinity gradient energy retrieved from the difference in the salt concentration between seawater and river water. In reversed electrodialysis a salt solution and fresh water are let through a stack of alternating cathode and anode exchange membranes. The chemical potential difference between salt and fresh water generates a voltage over each membrane and the total potential of the system is the sum of the potential differences over all membranes. It is important to remember that the process works through difference in ion concentration instead of an electric field, which has implications for the type of membrane needed. In RED, as in a fuel cell, the cells are stacked. A module with a capacity of 250 kW has the size of a shipping container. In the Netherlands, for example, more than 3,300 m³ fresh water runs into the sea per second on average. The membrane halves the pressure differences which results in a water column of approximately 135 meters. The energy potential is therefore e=mgΔh=3.3*106 kg/s*10 m/s²*135 meters ca.= 4.5*109 Joule per second, Power=4.5 gigawatts.
