Experimental Study of Solar Hydrogen Production Performance by Water Electrolysis in the South of Algeria

Current environment problems require the uses of clean process and durable sources in industrial activities. Hydrogen, produced by water electrolysis, represents high clean energy source. In this process, a high electrical energy rate is needed which led to costly product. In order to remedy this issue, the uses of renewable energies are required. In this work, an experimental study of solar hydrogen production system by alkaline water electrolysis in Ouargla (Algeria) city is presented. The alkaline water electrolysis, with different NaOH concentrations, is feed by photovoltaic panels. The system is tested at different input conditions of voltages and currents. Effects of temperature and NaOH electrolyte concentration on hydrogen production are examined (C) 2012 Published by Elsevier Ltd.
