Researchers from the German University of Technology in Oman (GUtech) and Poland’s Research and Innovation Centre Pro-Akademia (RIC – Pro-Akademia) are working together on the 'WASTE4H2' study, which focuses on the simultaneous treatment of industrial wastewater and hydrogen generation. This collaboration is significant for Oman, given the large volumes of produced water generated by oil and gas production. The study, funded by the Polish National Center for Research and Development, aims to develop a technology that can effectively treat industrial wastewater from oil refining and petrochemical operations, while also producing hydrogen using renewable energy sources. The innovative technology being developed utilizes plasma-driven solution electrolysis powered by hybrid photovoltaic-thermal collectors. This approach could offer sustainable and cost-effective alternatives to traditional wastewater treatment methods, which often produce volatile and toxic by-products. As part of the study, a lab technology demo is being constructed to test the automatic cleaning system for the collectors. GUtech is involved in studying the technology's components and subsystems in a near-real environment, while RIC – Pro-Akademia leads the consortium and oversees the project's design and construction. The final phase of the study will involve transporting the systems to Oman for testing at GUtech's facilities to evaluate the technology's efficiency in practical conditions. Overall, the collaboration between GUtech and RIC – Pro-Akademia aims to advance sustainable practices in industrial wastewater treatment and hydrogen generation, potentially offering a game-changing solution for the environmental challenges posed by oil and gas production in Oman.
