Manganese Oxide/Manganese Sulfate Based Solar Thermochemical Water Splitting Cycle

摘要

Solar H2 production via two-step thermochemical Manganese oxide – Manganese Sulfate (MnO-MnS) water splitting cycle is thermodynamically investigated. In the first step, the MnSO4 is thermally reduced to MnO, O2, and SO2. In the second step, the reduced MnO is reoxidized via water splitting reaction which results in H2 production. By using HSC Chemistry software, the thermodynamic equilibrium compositions associated with the thermal reduction and water splitting reactions are identified. Furthermore, the solar-to-fuel energy conversion efficiency of the cycle is determined by performing solar reactor efficiency analysis.
