    Abstract: Methods comprising: evaporating a catalyst source to produce a catalyst gas; condensing the catalyst gas to produce a catalyst vapor comprising catalyst droplets suspended in a gas phase; and contacting the catalyst vapor with a hydrocarbon gas to catalyze a decomposition reaction of the hydrocarbon gas into hydrogen gas and carbon. And, systems comprising: a catalyst source evaporator that provides a first stream to a reactor; a hydrocarbon source that provides a second stream to the reactor; a cooling column coupled to the reactor via a third stream comprising hydrogen, catalyst liquid, solid carbon, optionally catalyst gas, and optionally unreacted hydrocarbon gas such that the cooling column receives the third stream from the reactor; and wherein the cooling column has effluent streams that include (a) a fourth stream that comprises hydrogen and optionally catalyst gas and (b) a fifth stream that comprises catalyst liquid.

    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 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 ion exchange membrane is disposed between the first and second reservoirs, and a second type of ion exchange membrane, different from the first type, is disposed between the respective electrodes and reservoirs.

    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.
