It is known that, the available power from a photovoltaic system is unpredicted and
differs with climatic changes, so it has an intermittent nature, in other words it is unable to
supply the load continuously and steadily. Because of that, storage
methods of its energy
must be studied to use it again in a way that could be predicted. Hydrogen production is
one of these methods by connecting the PV system to water electrolysers, and this stored
hydrogen could be used either in fuel cells or burning it to get thermal energy. This study
focuses on PV system and the available energy taken from it, and the electrolysers and its
requirements and products. Making a mathematical model would be done and plotting the
curves that represent the system by programming it using MATLAB. A simple numeral
example that clears the system would be calculated. By this way, the energy efficiency
would be between 23 to 67 % according to the way the produced hydrogen is used.
Hydrogen production, vector of energy, by water electrolysis can be economically
viable by using electrical energy from renewable sources such as photovoltaic solar
energy. In this research was the study of solar hydrogen production using electroly
ser
based on polymeric exchange membrane electrolysis technology manufactured locally at
the Faculty of Technical Engineering in Tartous. The experimental studies were achieved
in two different methods: the first, direct coupling to the hydrogen electrolyser with PV
module. The second method, designed PV-electrolyzer system consists of the following
components: PV module, a maximum power point tracker (MPPT), A DC-DC converter,
which is used to operate the system at the maximum power of the PV system at all times
and to supply the necessary DC current to the electrolyzer, and tank hydrogen. The results
showed that the second method more effective and highly efficient when compared with
the first method because of the change in the intensity of solar radiation during the day.
Also, results show that some additives such as (KOH) play an important role in enhancing
the ionization process of the electrolyte liquid and improve process flow.
