    Thermodynamic efficiency analysis of ZnO/Zn based solar thermochemical CH4 reforming and H2O splitting cycle by R.Bhosale, Rahul

    Published 2020
    “…In case of the ZS process, the rise in the CH4/ZnO ratio from 0.1 to 1 resulted into an upsurge in the total solar energy required to run the cycle ( _Q solar ZS) and solar-to-fuel energy conversion effi- ciency ( hsolar to fuel ZS) by 460.1 kW and 13.0%, respectively. For the ZSH process, the total solar energy required to run the cycle ( _Q solar ZSH ) was decreased from 598.3 to 595.9 kW and the solar-to-fuel energy conversion efficiency ( hsolar to fuel ZSH ) was increased from 76.6 to 76.7% with the upturn in the WS temperature (TL) from 500 to 675 K. …”
