We have presented a method for the electrochemical production of H 2 utilizing inexpensive Municipal Solid Waste (MSW) as a feedstock. This cycle uses the chemical reduction of H 2 SO 4 to regenerate SO feedstock for use in an aqueous SO 2 -depolarized cell. This cycle may allow for the valorization of contaminated feedstocks because it bypasses the need for steam-reformation catalysts that are typically sensitive to such contaminants. MSW contains high levels of sulfur and other contaminates and therefore already requires significant tail-gas cleaning to remove gaseous pollutants. Our proposed cycle is one of many possible routes to H 2 production from biomass reacted with elemental sulfur, so experimental work is needed to demonstrate the efficacy of this process. While each step has been demonstrated commercially, technical feasibility would necessitate actual construction of the system. This stepwise decomposition of organic materials into H 2 and CO 2 using sulfur intermediates allows for each step to be independently optimized, similar to thermochemical methods for the decomposition of water. The proposed holds promise to sequester significant amounts of carbon while generating H 2 from MSW by converting decomposable biomass into more chemically inert biochar.
