  Electrodialytic technologies are clean up processes based on the application
of a low-level electrical current to produce electrolysis reactions and the
consequent electrochemically induced transport of contaminants. These
treatments inherently produce electrolytic hydrogen, an energy carrier, at the
cathode compartment, in addition to other cathode reactions. However, exploring
this by-product for self energy generation in electroremediation has never been
researched. In this work we present the study of hydrogen production during the
electrodialytic treatment of three different environmental matrices.
