Thermodynamic Analyses of Fuel Production via Solar-Driven Non-stoichiometric Metal Oxide Redox Cycling. Part 2. Impact of Solid–Gas Flow Configurations and Active Material Composition on System-Level Efficiency

Li, Sha; Wheeler, Vincent; Kreider, Peter; Bader, Roman; Lipiński, Wojciech

Description

We present an advanced thermodynamic model for a water-splitting solar reactor system employing Zr-doped ceria as the redox material and inert sweep gas to obtain the desired oxygen partial pressures in the reduction chamber. Conservation of mass and species, conservation of energy, and the Gibbs’s criteria are employed to predict solar-to-fuel efficiencies. Efficiencies vary widely with operating conditions--reactor temperatures and pressures--in addition to material thermodynamic properties,...[Show more]
