Seawater with brine (REAPower)

Although the seawater-brine combination is much less abundant than the seawater-river water combination, there are very promising possibilities of using seawater-brine due to the fact that both the feed water compartments have high salt concentrations. The main downside of using a low concentration feed solution such as river water, is due to the very high internal stack resistance caused by the low conductivity. Using feed solutions with higher concentrations reduces the stack resistance significantly, and the resulting power generation using seawater and brine is magnitudes higher than with a system using seawater and river water as feed solutions. Brine can be sourced from the waste streams of either a salt production facility or a seawater desalination plant, transforming an otherwise costly by-product into a power producing resource. The REAPower project, an international Blue Energy project of which REDstack is a contributing partner, is focused on developing RED applications using a seawater and brine as feed waters. The concept has been successfully implemented on the Italian island of Sicily in a facility that produces salt directly from the Mediterranean Sea.
An interesting project, not yet completely realized, involving partners in Israel and Jordan is focused on the Rea Sea and the Dead Sea, specifically related to desalination. Supplementing the desalination process with an RED unit would significantly reduce the cost of water treatment.
