Abstract: An electrodialysis apparatus comprises a first reservoir wherein salt dissolved in solvent is reduced below a threshold concentration and a second reservoir wherein the salt concentration increases. A first electrode contacts a first solution of a first redox-active electrolyte material, and a second electrode contacts a second solution of a second redox-active electrolyte material. A first type of membrane is disposed between the first and second reservoirs and a second type of membrane is disposed between the first electrode and the first reservoir and between the second electrode and the second reservoir. A color measuring device is coupled to at least one of the solutions, and a control system is configured to modify the value of a property of at least one of the first and second solutions in response to detecting a color value of one of the solutions exceeding a threshold color value.

Abstract: Ferrocene based redox-active compounds have a total number of cyclopentadienyl substituents that is three or greater per ferrocene core. The cyclopentadienyl substituents generally have a linker and a solubilizing group. An aqueous solution of the redox-active compound and a salt may be used as an electrolyte. Aqueous compositions including the redox-active compounds may be used in electrodialysis systems.

Abstract: An electrochemical device comprises a first type of membrane disposed between first and second reservoirs containing an input solution, and a second type of membrane, different from the first type, is disposed between a first redox-active electrolyte chamber and the first reservoir and disposed between a second redox-active electrolyte chamber and the second reservoir. The first type of membrane and one of the second type of membranes form a membrane pair and the pair has an area specific resistance below y=5065.3x3−1331.1x2+90.035x+39 Ohm cm2 when the pair is equilibrated in an electrolyte and for at least part of a range where 0

Abstract: A system includes an electrodialysis device with a salinate chamber through which a salinate stream flows. A desalinate chamber is separated from the salinate chamber by a central, ion-selective membrane. A desalinate stream flows through the desalinate chamber. An anolyte chamber and a catholyte chamber are on opposite outer sides of the salinate and desalinate chambers and separated therefrom by first and second ionic exchange membranes. A solvent exchange interface is in contact on a first side with the salinate stream and is in contact a media flow on a second side. The solvent exchange interface moves a solvent from the media flow to the salinate stream.

Abstract: A desalination and energy storage system comprises at least one water reservoir, at least one negative-ion redox electrode, at least one positive-ion redox electrode, a cation-exchange membrane disposed between the at least one negative-ion redox electrode and the water reservoir, and an anion-exchange membrane disposed between the at least one positive-ion redox electrode and the water reservoir. The at least one water reservoir comprises an input and an output, wherein water in the at least one water reservoir is reduced below a threshold concentration during a desalination operation mode. The at least one negative-ion electrode comprises a first solution and is configured to accept, and have, a reversible redox reaction with at least one negative ion in the water, and the at least one positive-ion electrode comprises a second solution and is configured to accept, and have, a reversible redox reaction with at least one positive ion in the water.

Abstract: A solution flows through a salinate chamber and a desalinate chamber of an electrochemical cell. Solutes are moved from the desalinate chamber to the salinate chamber to create respective solvent and concentrate streams from the desalinate and salinate chambers. The concentrate stream flows to a recombination cell where it is combined with a solvent. The combination causes at least one of an absorption of heat within the recombination cell and emission of heat from the recombination cell.

Abstract: Air flows across an air-liquid interface such that liquid desiccant flowing through the interface absorbs water from the air and is thereby diluted to form an output stream. The output stream is circulated through an electrodialytic stack having a central ionic exchange membrane and first and second outer ionic exchange membranes. A redox shuttle loop circulates around the first and second outer ionic exchange membranes. A voltage is applied across the electrodialytic stack, which regenerates the liquid desiccant.
