STRATEGIES FOR DEVELOPING PHOTOVOLTAIC SYSTEMS FOR CLEAN HYDROGEN PRODUCTION
Abstract
The transition to renewable energy sources is a key strategy for reducing carbon emissions and ensuring energy sustainability. This study explores the integration of photovoltaic (PV) systems for hydrogen production and storage in Constan?a County, Romania. The region benefits from high solar potential, making it an optimal location for implementing solar energy solutions. The proposed system converts solar energy into electricity through photovoltaic panels, which is then used to power an electrolyzer for hydrogen production. The generated hydrogen can be stored and utilized as a clean energy carrier, contributing to grid stability and reducing dependence on fossil fuels. Solar energy technology is instrumental in facilitating the sustainable production of hydrogen. While conventional methods depend on fossil fuels such as natural gas, coal, and oil, this study investigates environmentally friendly alternatives. Although green hydrogen production entails higher initial costs, advancements in low-carbon technologies have been accelerating cost reductions. This research presents a microgrid-based model incorporating a self-sustaining DC islanded system that supplies electricity to an electrolyzer, utilizing solar energy and integrated storage solutions. The proposed model serves as a valuable framework for assessing the performance and operational characteristics of sustainable hydrogen production. Over a simulated period of one week, it evaluates hydrogen generation dynamics, examining direct solar energy conversion as well as storage-assisted energy supply. By employing a multi-domain approach that includes electrical, thermal liquid, and thermal gas perspectives, the model provides a comprehensive analysis of hydrogen production processes. To validate the feasibility and efficiency of the system, simulations will be conducted using HOMER (Hybrid Optimization of Multiple Energy Resources) software. This tool enables an in-depth analysis of energy production, consumption, and storage, allowing for a detailed evaluation of system efficiency under various operational conditions. The results of these simulations will offer critical insights into optimizing renewable energy-driven hydrogen production in off-grid environments, contributing to the advancement of sustainable energy solutions.
