Exergoenvironmental analysis of the integrated copper-chlorine cycle for hydrogen production

Faran Razi et al.

Summary: Thermochemical water-splitting cycles have the potential to produce sustainable hydrogen in an environmentally friendly manner. This study evaluated the Cu-Cl thermochemical cycle at Ontario Tech University and showed that improving the exergy efficiencies of cycle components can reduce environmental impacts. The hydrolysis step accounts for 60% of the component-related environmental impact, and improving exergy efficiencies can reduce cumulative environmental impact.
