Summary: The present research compares and optimizes three integrated energy systems for hydrogen production, power generation, and water desalination. The systems include heliostat field collectors, photovoltaic panels, Rankine and organic Rankine cycles, and multi-effects water desalination systems. The main difference lies in the type of electrolyzer used, namely solid oxide electrolyzer cell (SOEC), polymer electrolyte membrane electrolyzer (PEM), and alkaline electrolyzer. The study analyzes the performance of these electrolyzers from both exergy and economic perspectives at their optimum conditions, and the results show that the integrated SOEC system achieves the highest exergy efficiency and hydrogen production rate.
