Green Hydrogen And Renewable Energy, Principles, Technologies, Applications And Future Perspectives

Renewable hydrogen has emerged as a promising clean energy carrier for supporting the transition toward sustainable and low-carbon energy systems. Among renewable technologies, photovoltaic-powered proton exchange membrane (PV–PEM) electrolysis represents an efficient and environmentally friendly approach for green hydrogen production. This work investigates PV–PEM hydrogen production through mathematical modeling, experimental validation, optimization, and techno-economic assessment. The developed models are experimentally validated under the climatic conditions of Ouargla, Algeria, while the Remora Optimization Algorithm (ROA) is employed to accurately estimate the parameters of the photovoltaic double-diode model. The study is further extended to the optimal design of a stand-alone solar-powered hydrogen refuelling station using HOMER Pro. The photovoltaic array, battery energy storage system, PEM electrolyzer, hydrogen storage tank, and converter are optimally sized to satisfy both electrical and hydrogen demands. System performance is evaluated in terms of electricity generation, hydrogen production, environmental impact, and economic indicators, including LCOE, LCOH₂, and NPC. The results confirm that the proposed PV–PEM system is technically reliable, economically feasible, and environmentally sustainable, providing an effective solution for decentralized green hydrogen production under the climatic conditions of southern Algeria.
