Analysis of solar hydrogen production in Algeria: Case of an electrolyzer-concentrating photovoltaic system

The results are reported and discussed. The potential at different locations in Algeria is determined. An inter-comparison between different technologies is carried out. For the system with the Fresnel reflector, the results show that the mean value over the country of the hydrogen production potential per unit cell area is about 0.14 kg H2/m2 day for the least favorable month; while this value is about 0.19 kg H2/m2 day for the most favorable month. For the system with the parabolic trough reflector, these values are about 0.10 kg H2/m2 day for the least favorable month and about 0.17 kg H2/m2 day for the most favorable month. Results show that electrolyzer-concentrating photovoltaic system is more appropriate for large scale production of hydrogen.
