According to aspects described herein, methods and systems provided by the present invention for hydrogen gas production include a RED stack including one or more RED subunits, and use of a saline material including a heat regenerable salt. The salinity driven energy, provided by the one or more RED subunits, completely eliminates the need for an external power source to produce hydrogen gas.

Methods for hydrogen gas production

Systems and methods for microbial processes of generating products such as electrical power, hydrogen gas and methane, are provided according to aspects of the present invention which include a reaction chamber having a wall defining an interior of the reaction chamber and an exterior of the reaction chamber; an anode at least partially contained within an anode compartment of the reaction chamber; a plurality of exoelectrogenic microorganisms disposed in the anode compartment; a cathode at least partially contained within a cathode compartment of the reaction chamber; a conductive conduit for electrons in electrical communication with the anode and the cathode; and a reverse electrodialysis stack comprising a plurality of plurality of alternating anion selective barriers and cation selective barriers disposed between the anode and the cathode defining one or more saline material compartments and one or more lower-saline material compartments.
