Keywords:
alkaline electrolysis, green hydrogen, photovoltaic integration, renewable energy, water splitting, energy efficiency, sustainable productionAbstract
This paper presents a comprehensive analysis of hydrogen production systems through water electrolysis powered by renewable energy sources, with particular focus on alkaline electrolysis technology integrated with photovoltaic systems. The study investigates the optimal operating conditions for alkaline electrolyzers, examining the effects of KOH electrolyte concentration (25-30 wt%), electrode materials (316L stainless steel), and system integration parameters. Experimental results demonstrate that the combined PV-electrolyzer system achieves an overall efficiency of 13-15%, with hydrogen production costs ranging from $2-8/kg depending on system scale. The research reveals that temperature optimization (60-80°C) and current density control (200-400 mA/cm²) are critical factors for maximizing system performance.
