| description | <p dir="ltr">A thermodynamic equilibrium and efficiency analysis of the dysprosium oxide-based solar thermochemical H<sub>2</sub>O splitting (Dy-WS) cycle is conducted. The objective of this study is to understand the effect of partial thermal reduction (TR) of Dy<sub>2</sub>O<sub>3</sub> on the solar-to-fuel energy conversion efficiency (<sub>ηsolar to fuel Dy WS</sub>) of the Dy-WS cycle. The equilibrium analysis indicate a rise in the percentage TR of Dy<sub>2</sub>O<sub>3</sub> (%TR-Dy) from 0.3% up to 100% when the TR temperature (T<sub>H</sub>) is increased from 2000 K to 2530 K. The upsurge in the T<sub>H</sub> yielded a considerable surge in the Q<sub>solar reactor Dy WS</sub> and Q<sub>solar heater Dy WS</sub>. Overall results of this study showed that the<sub>ηsolar to fuel Dy WS</sub> is amplified from 0.6% to 6.5% in three zones (slow zone, medium-fast zone, and fast zone) as the T<sub>H</sub> is amplified from 2000 K up to 2280 K. A further rise in the T<sub>H</sub> from 2280 K up to 2530 K resulted in a drop in the<sub>ηsolar to fuel Dy WS</sub> from 6.5% to 3.5%. By employing the heat recuperation, the<sub>ηsolar to fuel HR Dy WS</sub> is improved further up to 11.4% (at T<sub>H</sub> = 2280 K).</p><h2>Other Information</h2><p dir="ltr">Published in: Fuel<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.fuel.2020.118249" target="_blank">https://dx.doi.org/10.1016/j.fuel.2020.118249</a></p> |
