Thermochemical hydrogen production with a copper–chlorine cycle. I: oxygen release from copper oxychloride decomposition

Towards integration of hydrolysis, decomposition and electrolysis processes of the Cu–Cl thermochemical water splitting cycle

“…Therefore, it is important to find a medium that can store and distribute the intermittent and off-peak energy, hence reducing the "peaks and valleys" to help achieve the demand following profile. Hydrogen production at the intermittent and off-peak hours is a promising option [1] because hydrogen has a higher energy density than fossil fuels and its oxidization does not emit GHGs [2].…”

Thermalhydraulic analysis and heat transfer correlation for an intermediate heat exchanger linking a SuperCritical Water-cooled Reactor and a Copper-Chlorine cycle for hydrogen co-generation

“…The typical forms of the CueCl cycle found in recent literature are the 5-step, 4-step hybrid and 3-step cycles [34e36]. Several strengths of the cycle include a relatively low maximum temperature requirement (w530 C), favourable reaction kinetics for oxygen and hydrogen production steps and the opportunity to recycle heat generated through exothermic reactions [33]. The required external heat input is dependent upon the reaction characteristics of the cycle.…”

“…Thermochemical cycles are one such alternative, first investigated in the 1970's with resurgence in the last several years. Of the over 200 thermochemical cycles identified in literature reviews, very few have progressed beyond initial theoretical calculations, due in part to limitations in cycle efficiencies, extremely high temperature requirements or poor reaction characteristics [33].…”
