Abstract: A system comprises a first electrode, an electrolyte membrane, and a second electrode. The first electrode is configured to reduce oxygen in a gas to an oxygen carrier ion at an intermediate temperature. The electrolyte membrane is configured to transport the oxygen carrier ion, and the second electrode is configured to oxidize the oxygen carrier ion to an oxygen molecule. Oxidation of the oxygen molecule consumes less than four electrons.

Abstract: An energy storage system employing a reversible salination-desalination process includes an electrochemical desalination battery (EDB) unit including an anode and a cathode. The EDB unit runs a salination process while storing energy from a direct current power supply unit, and runs a desalination process while releasing energy to an electrical load. The energy storage system can store power from a variable output electrical power supply unit such as solar cells and wind turbines while running a salination process, and release energy, e.g., during peak energy demand hours while running a desalination process. Combined with a capacitive deionization (CD) unit, the energy storage system can generate fresh water by running desalination processes in the EDB unit and the CD unit while releasing stored energy from the EDB unit. The energy storage unit can function as a dual purpose device for energy storage (load shifting) and fresh water generation.

Abstract: An electrodialytic battery system comprises an electrodialysis apparatus having first and second reservoirs, wherein concentration of an input solution in the first reservoir increases and concentration of the input solution decreases in the second reservoir during an operation mode. A first redox-active electrolyte chamber comprises a first electrode and a first solution of a first redox-active electrolyte material and has a reversible redox reaction with the first electrolyte material to drive an ion into the first reservoir. A second redox-active electrolyte chamber comprises a second electrode and a second solution of a redox-active electrolyte material and has a reversible redox reaction with the second electrolyte material to accept an ion from 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 electrode chambers and reservoirs.

Abstract: An electrochemical device suited to modifying a carbon dioxide concentration in an interior space includes a cathode chamber with an inlet which receives a feed gas containing carbon dioxide. A reduction catalyst layer in the cathode chamber reduces carbon dioxide in the gas to form an ionic carrier species. An anode chamber with an outlet outputs a gas comprising carbon dioxide. A solid electrolyte membrane spaces the anode chamber from the cathode chamber and transports the ionic carrier species between the cathode chamber and the anode chamber. The membrane includes an ionic liquid. An oxidation catalyst layer in the anode chamber oxidizes the ionic carrier species to form carbon dioxide. A voltage source provides a voltage difference across the membrane.
