🌊⚡ Effect of Water Quality Produced at Each Stage of the Seawater Desalination Process on Hydrogen Production in Water Electrolysis
The global transition toward clean energy has intensified research on green hydrogen production through water electrolysis. However, seawater cannot be used directly because dissolved salts, minerals, and organic impurities interfere with the electrochemical reactions. Therefore, seawater must undergo multiple purification stages through desalination technologies such as Reverse Osmosis , which gradually improve water quality before it becomes suitable for electrolysis. Understanding how water quality changes at each desalination stage and how it influences hydrogen generation efficiency is crucial for sustainable energy systems. 🌱🔬 🌊 1. Raw Seawater Characteristics Raw seawater contains high concentrations of salts, magnesium, calcium, sulfates, microorganisms, and suspended solids . These contaminants can damage electrolyzer electrodes, cause scaling, and reduce hydrogen yield. If untreated seawater is used in electrolysis, it may lead to unwanted chemical reactions such as...
