Energy generation by reverse electrodialysis

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In this work, the process of generating electricity from the water salinity gradient (RED) using the Russian produced ion exchange membranes MK-40 and MA-41 was investigated. The experiments were carried out with a saturated brine of sodium chloride in a chamber with salt water and with a solution of sodium chloride with a ...
