Abstract: A method for transporting nitride (N3?) ions in an electrochemical cell includes providing nitrogen to a first side of a solid electrolyte membrane to form nitride ions and transporting the nitride ions across the solid electrolyte membrane. The solid electrolyte membrane includes a metal nitride. The method may be used for ionically-mediated separation and/or compression of nitrogen or to form ammonia.

Abstract: A porous material including polymerized units containing pores is provided, which can be employed for desalination applications. Each of the units includes at least one aromatic amino group and at least one hydroxyl group. The aromatic amino groups and the hydroxyl groups are arranged on surfaces of the pores in geometries configured to capture sodium chloride from an aqueous environment. The porous material can be provided as particles or a sponge. The porous material can be manufactured from a solution including monomers, a porogen, and an initiator by a polymerization process. The porous material can be reused after a desalination process by treatment with deionized water. A steam generation apparatus can be employed to facilitate removal of sodium chloride from the porous material in which sodium chloride is captured.

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.

Abstract: Today, energy requiring equipment commonly relies on batteries for power. The excessive weight and size of batteries severely limits their performance. Described herein is a lightweight portable energy system which includes an ultra-high capacity hydrolysable hydride gel cartridge for use in supplying hydrogen gas to hydrogen based energy generators. Hydrolysable hydride reactivity is controlled by tuning the amounts of hydrophilic and hydrophobic content in a polymer gel encapsulant of the cartridge.

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.
