Design and efficiency estimation of a thermochemical system of hydrogen production
Abstract
An iron-chlorine thermochemical cycle for the production of hydrogen from water was investigated. The energy required in H2O-HCl separation is of special importance. Starting from a state of thermodynamic equilibrium, it was possible to estimate the energy expended. The efficiency thus determined was about 18%. Improved separating processes could raise this to about 27%; hence, the efficiency is below that obtained by present-day electrolytic processes.
