“…The thermochemical SeI and hybrid CueCl water splitting cycles have envisaged efficiencies of w45%, based on their required energy input [34,35]. When coupled with high temperature nuclear reactors the total hydrogen generation efficiency of these systems must degrade to 40À43% due to various energy losses at heat (and electricity) transfer/ Fig.…”

“…There five known configurations of the CueCl cycle as indicated in Table 5 from which it results that the electricity required by the cycle can be as low as 53% of that for water electrolysis. A comprehensive review of research and development progress on CueCl cycle is revised in [34,35]. Approximately a 43% net efficiency is envisioned with this CueCl cycle, which is a significant margin of improvement of more than one-third over water electrolysis.…”

Hydrogen can be produced by direct or single‐step splitting of water. The Gibbs free energy change for direct thermochemical water splitting is zero at about 4300 K at 1 bar. However, in practice, direct thermochemical splitting of water poses challenging high‐temperature materials and product separation issues, among others. One way to lower the extremely high temperatures required for direct splitting of water and mitigate gas separation issues is the use of multistep cycles. To date, more than 350 thermochemical cycles for splitting water has been conceived. Of these, fewer than two dozen cycles still remain subject to further research and development. Among them are several “sulfur family” cycles as well as a number of volatile and nonvolatile metal oxide cycles. All of these cycles consist of at least two process steps, and some are hybrid cycles requiring both heat and work (e.g., electricity) input. This article presents a brief review of the status of multistep thermochemical water‐splitting cycles (TCWSCs) for the production of hydrogen.

Ceramic carbon electrodes (CCE) containing poly aminopropyl siloxane (PAPS) were fabricated by the sol-gel method. These CCEs have previously been shown to exhibit high performance towards the anode reaction of the electrolytic process used in the Cu-Cl thermochemical cycle for hydrogen production, with optimal performance being achieved at 36 wt% PAPS. Using cyclic voltammetry, electrochemical impedance spectroscopy, and scanning electron microscopy, the peak performance at 36 wt% PAPS was explained in terms of the optimization of carbon surface area, anionic transport and electronic conductivity. In addition, we also demonstrated the electrolysis performance in the full cell.
