ABSTRACT: This article is in the field of research into the storage of renewable
energy production. One of the main obstacles to the rapid development of
renewable energies is the storage of the energy produced at low cost and with
good efficiency. The production of hydrogen from renewable energies is a
promising solution. The present work evaluates the potential of hydrogen
production by electrolysis from solar photovoltaic and wind renewable energies
in the city of Douala in Cameroon. The methodological approach used is based on
the semi-empirical modelling approach of an alkaline electrolyser associated
with the solar panel or the wind turbine. The simulation results obtained on
the MATLAB/Simulink platform show that the average hydrogen production
potential is estimated at 0.55 Nm3/h for a PV panel supply, which
corresponds to average energy efficiency of 70%, and at 0.675 Nm3/h
for a wind turbine supply, which corresponds to average energy efficiency of
84%. These results show the need to promote this technology, whose efficiency
can be improved depending on the choice of site.
