Abstract: A system comprises an electrodialysis apparatus, which includes first and second reservoirs, wherein a salt concentration in the first reservoir reduces below a threshold concentration and salt concentration in the second reservoir increases during an operation mode. A first electrode comprises a first solution of a first redox-active electrolyte material, and a second electrode comprises a second solution of a second redox-active electrolyte material. In a first reversible redox reaction between the first electrode and first electrolyte material at least one ion is accepted from the first reservoir, and in a second reversible redox reaction between the second electrode and second electrolyte material at least one ion is driven into the second reservoir. A first type of membrane is disposed between the first and second reservoirs, and a second type of membrane, different from the first type, is disposed between the respective electrodes and reservoirs.

Abstract: A liquid desiccant regenerator configured to produce a first output stream with a higher concentration of a liquid desiccant than a first input stream. The regenerator also produces a second output stream with a lower concentration of the liquid desiccant than a second input stream. Regeneration of the liquid desiccant in the liquid desiccant regenerator decreases a temperature of the liquid desiccant regenerator. The system includes an air contactor coupled to the first output stream and exposing an input air stream to the first output stream. The first output stream absorbs water from the input air stream to form at least one diluted output desiccant stream. A heat pump of the system is thermally coupled to move the heat from the first output stream to the liquid desiccant regenerator. The heat moved to the liquid desiccant regenerator increases an efficiency of the liquid desiccant regenerator.

Abstract: An electrochemical system has a first reservoir receiving a feed stream. The feed stream includes a solvent and a solute different than the salt. A second reservoir receives a brine stream with a higher salt concentration higher than the feed stream. Electrodes contact a loop of redox- active electrolyte material causing reversible redox reactions. The reactions cause the loop to accept a first ion from the salt in the first reservoir and drive a second ion into the brine stream in the second reservoir. Three ionic exchange membranes of alternating type define the first and second reservoirs. A concentrate stream is output from the first reservoir, the concentrate stream having a second solute concentration greater than the first solute concentration.

Abstract: A system includes an electrochemical regenerator configured to receive a first solution having a first salt concentration and output a second solution having a second salt concentration lower than the first salt concentration and a third solution having a third salt concentration higher than the first salt concentration. The first and second solutions are sent to first and second reservoirs respectively absorb and emit heat in response to a phase change of one of the solutions. The absorption or emission of heat can be used in a heat pump system.

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.

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 redox-active compound is disclosed that is the reaction product of an electron-withdrawing monomer, a cross-linker, and a redox-active moiety. The cross-linker may be connected to the redox-active moiety through the electron-withdrawing functional group. The redox-active compound has a reduced form and an oxidized form and neither the reduced form nor the oxidized form is decomposed by oxygen. The redox-active compound may be used to create a pH gradient in a fluid stream. A redox-active composition may include the redox-active compound, a binder, and a current collector. The redox-active composition may be part of a membraneless electrochemical cell.
