Abstract: The present disclosure provides systems and methods for processing ammonia. The system may comprise one or more reactor modules configured to generate hydrogen from a source material comprising ammonia. The hydrogen generated by the one or more reactor modules may be used to provide additional heating of the reactor modules (e.g., via combustion of the hydrogen), or may be provided to one or more fuel cells for the generation of electrical energy.

Abstract: The system includes electrolyzers to generate acidic and alkaline effluent streams from saltwater. The electrolyzer include stacked pairs of porous anodes and cathodes that define feed channels into which reactants, e.g., hydrogen and brine, can be pumped to undergo an oxidation-reduction reaction. The porous cathode carries out the HER to generate H2, which floats upwards to the porous anode, where it is oxidized through the HOR. The reaction can thus progress in a self-maintaining manner. The HER creates an alkaline product stream with increased basicity, and the HOR an acidic product stream with increased acidity, compared to the inlet stream. Streams are pumped through the porous electrodes and the electrolyzer to sweep effluent through separate channels before they can combine. The alkaline product stream can have an alkalinity sufficient to drive metal ion precipitation in raw saltwater prior to feeding to the electrolyzer to reduce fouling/degradation of electrolyzer electrodes.
