In this work, we show the feasibility of using renewable energies, in particular photovoltaic systems, to produce hydrogen in order to meet energy needs while reducing greenhouse gas emissions. In this context, and in order to harness the saline water from Douar el Hamri (located 80 km north-west of Oujda), characterised by a conductivity of 4,000 µS/cm and a salinity level of over 2g/l, we have designed a system consisting of a 345 W PV panel and a boost-type DC/DC converter that feeds stainless steel electrolysers to break down the saline water into hydrogen and oxygen using electrolysis. This process produces ‘green’ hydrogen, a clean energy source that can be used by the Douar's inhabitants to run their generators and generate electricity. When the system is switched on and under lighting conditions of 1000 W/m2, the first results show the appearance of a significant quantity of hydrogen and oxygen. Compared with traditional methods of producing hydrogen, this approach offers advantages in terms of sustainability, reducing the carbon footprint and contributing to the energy transition to renewable sources.
