This study optimizes a hydrogen production system using sewage sludge gasification and solar PV in Oman, processing 125,000 m3/day of wastewater. It can generate 370 kg of hydrogen daily at $2.9-4.7/kg, with 60.4% biopower penetration under optimal conditions. Further work on syngas quality and socio-economic factors is needed for real-world deployment.

📄 Abstract（原文）
Biowaste generated from wastewater treatment plants (WWTPs) presents a promising opportunity for sustainable hydrogen generation. Currently, WWTPs manage their waste through processes that convert it into agricultural land, landfill leachate, and fertiliser. The UN‘s energy transition targets and Sustainable Development Goals (SDGs) are increasingly emphasising the importance of renewable energy sources, such as solar, wind, and biomass. Environmental guidelines are increasingly urging both industrial and non-industrial sectors to manage their waste effectively. Managing waste represents a significant commitment for industries and necessitates considerable capital investment. This study explores the use of syngas generated from gasifying sewage sludge, alongside solar energy, to power an electrolyser for hydrogen production. It also examines the associated technical and economic factors. The plant examined in this study has the capacity to process 125,000 m3 of sewage water per day. By harnessing solar energy, the system delivers 100% renewable power to the proposed H2 generation system. The optimisation studies done using HOMER Pro software indicate that the plant can generate 370 kg of sustainable hydrogen each day, with the cost of hydrogen ranging from $2.9 to $4.7/kg, depending on different combinations of power from syngas electric generators and solar PV arrays. At maximum biomass utilization and under optimal conditions, the observed biopower penetration is 60.4%. However, doing more studies that look at the quality of syngas, changes in the characteristics of sludge throughout the year, and the social and economic factors during implementation can help make the system ready for real-world use.
