Customer ServiceOne of the most sustainable ways to make hydrogen is to use solar energy to split water into hydrogen and oxygen. This can be done using photoelectrochemical (PEC) systems that combine a photovoltaic device and an electrolyzer device. The PV device absorbs sunlight and generates electricity that drives the electrolytic splitting of water.
The prodn. of hydrogen from water using solar energy via a two-step thermochem. cycle is considered. The 1st, endothermic step is the thermal dissocn. of ZnO (s) into Zn (g) and O2 at 2300 K using concd. solar energy as the source of process heat.
Improving hydrogen production using solar energy involves developing efficient solar thermochemical cycles, such as the copper-chlorine cycle, and integrating them better with solar thermal systems. Advancements in photolysis for direct solar-to-hydrogen conversion and improving the efficiency of water electrolysis with solar power are crucial.
