Scientists from Gabes University in Tunisia conducted a study on optimizing green hydrogen production through a PV-powered system. The research focused on the effects of PV panel orientation and water quality on efficiency levels. Their experiment, conducted in Gabès, Tunisia, during four summer days, revealed that a variable orientation of the PV panel significantly increased hydrogen production compared to fixed configurations. The team compared the use of demineralized and distilled water, noting that distilled water led to higher efficiency, albeit with potential environmental drawbacks due to the energy-intensive distillation process. The study emphasized the significance of considering factors like PV panel design, electrolyzer materials, and water quality in green hydrogen production systems. The researchers highlighted their findings in a publication titled 'Experimental assessment of the effects of water quality and PV panel orientation on green hydrogen production' in the International Journal of Thermofluids.
