Production of Hydrogen by Photovoltaic Using Seawater

In this paper, we present an experimental validation of green hydrogen production using a seawater electrolyzer. Hydrogen is an important future energy source for the world. Also, the use of seawater as an electrolyte presents an alternative source of water in view of the water stress problem. In order to carry out this experiment and to validate the results, a flat electrolytic cell has been set up with the use of seawater as an electrolyte. The electrolyzer is powered by a photovoltaic system. This system is composed of a photovoltaic panel connected in cascade with a serial DC/DC converter (buck). This last is piloted by the MPPT control, based on a P&O algorithm in order to take advantage of the maximum power point generated by the photovoltaic panel. This experiment aims to see the effect of the electrolyzer on the seawater. For that, two phases of the electrolysis of the seawater have been made, and an analysis of each sample is interpreted, in order to validate that the production of hydrogen is valid by using the seawater as an electrolyte.
