Use of Electrolysis to Produce H2 from Natural and Modified Water

Abstract

Hydrogen, as an energy carrier, cannot be found in its pure form in nature and must be generated through specific processes to be stored and utilized. The primary methods of producing hydrogen involve electrolyzing water or reforming and gasifying hydrocarbons. Herein, the nature of El‐Oued water on the production of hydrogen by the electrolysis process is investigated experimentally. The experimental work is divided into three parts: 1) the first one of 250 mL of distilled water and potassium oxide (KOH) of (1 mol L−1); 2) the second part of 250 mL of El‐Oued water and potassium oxide (KOH) of (1 mol L−1); and 3) the thrid part of 250 mL of El‐Oued water. The amounts of the produced hydrogen in these scenarios are measured and compared in controlled times. The results insured that the use of El‐Oued water only gives a very few amounts of hydrogen gas in the electrolysis of water. Moreover, distilled water can be replaced by El‐Oued water to produce hydrogen with the same amount of potassium oxide (KOH).
