Chemical looping hydrogen storage and production: Use of binary ferrite-spinel as oxygen carrier materials

Abstract

Chemical looping hydrogen storage and the recovery by redox of iron oxides were recommended as an emerging approach for large-scale hydrogen storage with a high volumetric hydrogen storage density. However, iron oxides should be operated at a high temperature (>800 °C) for its sufficient redox activity which would lead to a rapid deterioration of hydrogen storage performance over cycles. In this work, a series of ferrite-spinel materials A0.25Fe2.75O4 (A=Co, Cu, Ni, Zn or Mn) were prepared. Among all the additives to iron oxides, Co0.25Fe2.75O4 exhibits the high volumetric hydrogen storage density (~62.47 g·L-1) and average hydrogen production rate (~132 μmol·g-1·min-1) under 550 °C. Besides, the storage capacity maintained over 10 cycles. The volumetric hydrogen storage density of this material was proportionate to the most advanced Rh-FeOx containing rare-earth metal, thus it may have the potential of industry application
