Techno-economic of solar-powered desalination for green hydrogen production: Insights from Algeria with global implications

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.
