Magnesium–Chlorine Cycle for Hydrogen Production Driven by Solar Parabolic Trough Collectors

The study analyzes an integrated Magnesium-Chlorine Mg-Cl thermochemical cycle with solar parabolic trough system. Direct solar radiations have been estimated with tilted and tracking collectors in the Algerian desert. The results reveal that, tilted tracking axis aperture toward the south at local latitude angle is most efficient than does fixed tilted aperture facing south per local latitude angle with an average difference of 0,9 MWh/m2/year. Heat gain evolution from parabolic trough collectors is estimated to investigate heat sources. The best annual heat gain was observed in Tamanrasset with 7.919 and 19.99 MWh/m/year by fixed and tracking system, respectively. Hydrogen production rate from the process have been evaluated and compared under Algerian desert conditions. The maximum hydrogen production rate is obtained for Tamanrasset with 51,862 and 143,011 Ton H2/year by fixed and tracking system, respectively.
