Nuclear-Based Hydrogen Production via the Cu-Cl Thermochemical Cycle
Thermochemical water splittingin the Cu-Cl cycle can produce hydrogen directly from steam. Steam is decomposed into hydrogen and oxygen through intermediate chemical and electrochemical reactions of Cu-Cl compounds, as shown in Figure 1. While promising, there are still several fundamental scientific challenges that must be overcome in order to show that this cycle is viable. Research at UOIT is focused upon overcoming these challenges.
At the heart of this cycle is an electrolysis step involving the oxidation of CuCl and the generation of H2, as shown in Figure 2. Therefore, this step must be a highly a efficient process. Research in the Easton lab focuses on the fundamental understanding of electrode kinetics under conditions relevant to the thermochemical cycle and the development of novel electrode materials and electrode structures including ceramic carbon electrodes and advanced membrane materials.
