Abstract

Algeria, with its abundant solar energy resources and existing desalination infrastructure, has significant potential to emerge as a key player in the global green hydrogen market. This study presents a techno-economic analysis of integrating solar photovoltaic (PV) systems with desalination plants to produce green hydrogen sustainably. Results indicate that the Levelized Cost of Hydrogen (LCOH) can be reduced to 2.12–2.72 USD/kg, making it highly competitive compared to conventional hydrogen production methods. Additionally, this approach could cut carbon emissions by up to 90.000 tons annually, aligning with Algeria's climate commitments and energy diversification goals. The integration of Reverse Osmosis (RO) in desalination enhances efficiency, lowers energy consumption, and further reduces costs. By leveraging its solar potential, Algeria can strengthen hydrogen export opportunities and contribute to regional decarbonization efforts. The findings highlight the feasibility and economic advantages of this model, offering valuable insights for global implementation in regions with similar renewable energy potential.

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
