| Abstract |
| This paper presents a comparative study of two energy systems that integrate photovoltaic (PV) power, reverse osmosis (RO), and electrolyzer (EL) technologies, aimed at optimizing both water production and hydrogen storage. The first system (PV/RO) utilizes solar energy exclusively for water desalination, providing a sustainable solution for freshwater generation. The second system (PV/RO/EL) enhances this setup by directing excess solar energy to an electrolyzer for hydrogen production, which is subsequently stored in high-pressure tanks for later use or commercial sale. The study evaluates the technical performance and economic feasibility of each configuration by analyzing key metrics such as energy generation, hydrogen yield (kg), storage capacity, operational costs, and overall system efficiency. Additionally, the payback period and cost of water production are calculated to provide a comprehensive economic comparison. The results offer valuable insights into the benefits and trade-offs of integrating renewable energy with water and hydrogen systems, highlighting their potential in promoting sustainable and resilient resource management. |
