Abstract. The global demand for cleaner energy solutions has placed hydrogen at the centre of sustainable energy discussions. As a zero-emission fuel, hydrogen offers a promising alternative to fossil fuels, but traditional production methods like steam methane reforming (SMR) and electrolysis remain energy-intensive, expensive, and environmentally harmful due to their reliance on fossil fuels. This paper introduces an innovative approach to hydrogen production by utilizing wastewater as both a resource and an energy source. The system integrates Piezoelectric Generators (Piezoelectric Energy cells) made from Zinc Oxide (ZnO) and Polyvinylidene Fluoride (PVDF), which harvest mechanical energy from fluid movement and vibrations to generate electricity. Additionally, an IoT-based monitoring system is incorporated to track system performance, optimize energy harvesting, and enable real-time adjustments for improved efficiency. To further enhance energy harvesting, a Triboelectric Generator incorporating nylon and PTFE (Polytetrafluoroethylene) is integrated with the Piezoelectric Generators, capitalizing on frictional forces within the wastewater flow. This integrated approach provides a way to generate clean energy while also treating wastewater. By tackling both energy production and environmental cleanup at the same time, it offers a smart and sustainable solution to the growing challenges of water and energy management. Future research has the potential to explore utilization of piezoelectric and triboelectric generators for seawater electrolysis, expanding beyond wastewater-based hydrogen production to enable sustainable energy generation from ocean resources.
