The production of green hydrogen through water electrolysis, powered by solar energy, offers a promising solution for reducing global carbon emissions and addressing the challenges of intermittent solar resources. By serving as a versatile energy carrier, green hydrogen can mitigate the limitations of solar energy fluctuations. However, the conventional process demands significant electricity and water resources, potentially restricting its feasibility in arid climates. Recent research emphasizes the potential of harnessing sunlight and wastewater for renewable hydrogen production, thus minimizing water consumption and environmental impact [1,4]. This innovative project aims to develop a comprehensive system for wastewater treatment and green hydrogen generation, addressing the following key tasks:
(a) Identification of Suitable Wastewater Sources: Different types of wastewater, such as mining effluents, natural water, and seawater, will be analyzed to understand their compositions and suitability for the project;
(b) Solar-Driven Wastewater Treatment: An efficient solar-driven water treatment process will be designed to preprocess selected wastewaters. This will include tasks such as concentrating brine and producing pre-conditioned biomass and deionized water to facilitate subsequent electrolysis;
(c) Renewable Hydrogen Production: Utilizing solar-driven flow electrolysis, either through a commercial cell or a customized prototype, the pre-conditioned wastewater will be used to produce renewable hydrogen.
