A method can include performing a series of reactions in a closed cycle, the series of reactions consisting of a hydrolysis reaction where a redox reagent is oxidized to a corresponding oxidized redox reagent with water contemporaneously with the production of hydrogen; and a reduction reaction where the oxidized redox reagent is reduced to the redox reagent using a sulfurous reactant contemporaneously with production of sulfur dioxide.

In one aspect, the disclosure relates to a method for supplementing syngas to produce a precursor composition for synthesis of at least one industrially useful chemical, the method comprising contacting the syngas with an external source of hydrogen. In an aspect, industrially useful chemical comprises methanol and the external source of hydrogen comprises hydrogen produced by steam methane reforming (SMR), hydrogen produced by steam injected onto molten metals, or another hydrogen source. In some aspects, the external source of hydrogen comprises hydrogen produced by a halogen acid contacting scrap metal, wherein the halogen acid can be produced by gasifying a halogen-containing polymer such as, for example, polyvinylchloride (PVC), polyvinylidene chloride (PVDC), or any combination thereof. Also disclosed herein are systems useful for carrying out the disclosed methods.

A system for controlling contamination in hydrogen production from water-reactive aluminum includes at least one reaction vessel. For example, each reaction vessel may include a container, a conduit, and a plurality of baffles. The container may define a volume, and the conduit may define an orifice outside of the container and spaced away from the container. The plurality of baffles may be disposed in the volume to form a tortuous flow path through the volume to the orifice of the conduit to facilitate rapid production of a large quantity of hydrogen from water-reactive aluminum while reducing the likelihood that ejecta, aerosols, or a combination thereof, may escape the reaction vessel to interfere with end-use of the hydrogen produced.
