14. A liquid desiccant system, comprising:
an electrodialytic stack comprising:
a liquid desiccant loop with a diluted stream and a concentrated stream of liquid desiccant separated by a central ionic exchange membrane;
a redox shuttle loop comprising a positively charged ferrocene derivative and with first and second redox streams separated from the diluted stream and the concentrated stream of the liquid desiccant loop by respective first and second outer ionic exchange membranes of a different type than the central ionic exchange membrane; and
first and second electrodes that are operable to apply a voltage across the electrodialytic stack; and
an air-liquid interface in fluid communication with the concentrated stream of the liquid desiccant, the air-liquid interface exposing the concentrated stream of the liquid desiccant to air flowing across the air-liquid interface, the concentrated stream being diluted via absorption of water from the air to form an output stream, the output stream being circulated back into the liquid desiccant loop of the electrodialytic stack.
