Energy Generation with Capacitive Deionization Systems

CAPMIX (Capacitive Mixing) technologies are promising electrical generation processes under development which are used for obtaining renewable energy from mixing fluids with different salinities (such as seawater and fresh water). This mixture originates from places like the mouths of rivers naturally. Such technology is inherited from the deionization processes such as CDI (Capacitive Deionization). In this paper, both processes (CAPMIX and CDI) will be described, which can be understood as complementary, because a CDI cell, can be used for both applications. Furthermore, several tests to a commercial CDI cell will be carried out, working in both working modes, validating the previously commented.
