PRODUCTION OF HYDROGEN

Abstract

This study provides a systematic evaluation of hydrogen production methods, with focus on optimizing solar-powered alkaline electrolysis for sustainable energy systems. While analyzing conventional pathways (steam reforming, pyrolysis) and emerging alternatives (PEM/SOEC

electrolysis), the research identifies alkaline electrolyzers as the most viable technology for large- scale solar hydrogen in high-irradiation regions like Algeria. Through MATLAB simulations

validated by PVGIS data, we demonstrate how 80°C operation improves electrolyte conductivity (115.5 S/m) while managing overpotentials (total cell voltage: 2.24 V). Practical implementation challenges are addressed through: (1) sensitivity analysis of Faradaic/PV efficiencies, (2) comparative assessment of storage/transport methods, and (3) levelized cost modeling (€4.50/kg at optimized conditions). The work bridges theoretical principles with deployable solutions, offering actionable insights for renewable hydrogen projects in sun-rich developing economies.
