“Hydrogen sulfide (H2S) is widely available in oil and gas reservoirs and has the potential to become an energetically favorable source of hydrogen. Nevertheless, its electrochemical separation into H2 and elemental sulfur has not been successfully achieved at the industrial scale due to sulfur poisoning of the electrodes at the sulfur oxidation half-reaction. Martin, in collaboration with the EXPEC ARC, Saudi Aramco, reviewed the different technologies and approaches explored to improve the energy efficiency and stability of H2S electrolytic systems at temperatures below the sulfur dew point. The review paper was published in Frontiers in Chemical Engineering.”
