Abstract
Seawater presents itself as a potential resource that can contribute to the advancement of sustainable development goals in the context of an energy transition. Salinity gradient power (SGP) is a promising source of marine energy with the potential to meet the power demand of specific communities, especially those living near river mouths, where the salinity difference is naturally available. In the Colombian context, SGP availability has been studied for several rivers, with the highest potential found at the mouth of the Magdalena River in Barranquilla, accounting for 97% of the total potential in the country. According to estimations of average specific site potential calculated by [1], it is possible to obtain 1.3 MJ/m3 of treated seawater by installing an SGP facility in that location. Both electrochemical and rheological data are necessary to assess the suitability of CFE for scaled-up RED devices and to develop design proposals that ensure reliable and efficient operation. In addition, CFE scale-up developments are applicable to other technologies like flow capacitors for energy storage and devices for mineral recovery, which are of interest in the scenario of the development of a marine economy.
