In the energy transition from fossil fuels to renewables, the tendency is to benefit from ultra-sour natural gas reserves, whose monetization was previously considered unviable. The increasing H₂S content together with the growing concern about emissions that are harmful to the environment, make necessary the development of efficient strategies for pollutants management. Although large-scale H₂S conversion is well-established through the Claus process, novel technologies for H₂S valorization could be a reliable alternative for waste-to-valuable chemicals, following the circular economy. In this perspective, technologies such as Hydrogen Sulfide Methane Reformation (H₂SMR), non-thermal plasma, photocatalytic decomposition, decomposition through cycles and electrolysis are analyzed for the H₂ production from H₂S. They represent promising alternatives for the simultaneous H₂S valorization and H₂ production, without direct CO₂ emissions, as opposite to the traditional methane steam reforming. The various H₂S conversion routes to H₂ are examined, highlighting the advantages and disadvantages of each of them. This review focuses in particular on the most promising technologies, the H₂SMR and the non-thermal plasma, for which preliminary process scheme and techno-economic analysis are also reported. Finally, the major research gaps and future developments necessary to unlock the full potential of hydrogen sulfide valorization as a sustainable pathway for hydrogen production are discussed.
