Abstract

The computational thermodynamic analysis of a samarium oxide-based two-step solar thermochemical water splitting cycle is reported. The analysis is performed using HSC chemistry software and databases. The first (solar-based) step drives the thermal reduction of Sm 2 O 3 into Sm and O 2 . The second (non-solar) step corresponds to the production of H 2 via a water splitting reaction and the oxidation of Sm to Sm 2 O 3 . The equilibrium thermodynamic compositions related to the thermal reduction and water splitting steps are determined. The effect of oxygen partial pressure in the inert flushing gas on the thermal reduction temperature ( T H ) is examined. An analysis based on the second law of thermodynamics is performed to determine the cycle efficiency ( η cycle ) and solar-to-fuel energy conversion efficiency ( η solar−to−fuel ) attainable with and without heat recuperation. The results indicate that η cycle and η solar−to−fuel both increase with decreasing T H , due to the reduction in oxygen partial pressure in the inert flushing gas. Furthermore, the recuperation of heat for the operation of the cycle significantly improves the solar reactor efficiency. For instance, in the case where T H = 2280 K, η cycle = 24.4% and η solar−to−fuel = 29.5% (without heat recuperation), while η cycle = 31.3% and η solar−to−fuel = 37.8% (with 40% heat recuperation).
