Both chemical looping processes and oxygen permeable ceramic membranes require a gas–
solid surface reaction to occur in order to function; the two approaches have much in …

The high reaction temperature required for chemical looping in water splitting presents
challenges in terms of producing stable oxygen carrier materials (OCMs). The currently …

Interest in hydrogen as a possible energy vector is powered by the depletion of fossil fuel
feedstocks as well as concerns over global warming, which brings new environmental …

A stable energy supply will require balancing the fluctuations of renewable energy
generation due to the transition to renewable energy sources. Intraday and seasonal …

Since the Paris Agreement was signed at the end of 2015, 1 the aims of multilateral climate
policy have been clear. Nations from across the world pledged to limit the increase in global …

Chemical looping combustion (CLC) is a cyclic process in which an oxygen carrier (OC), is
firstly reduced by a fuel, eg. syngas, and then oxidised in air to produce heat. If the OC is Fe …

Cyclical oxidation/reduction behavior of iron-based powders and porous pellets is of great
interest for iron-air batteries, steam-iron, and chemical looping processes, but extended …

In this study, renewable hydrogen production was achieved by coupling of water splitting
and glycerol oxidation reforming by chemical looping technology (CLWS-GOR) using the …

The use of binary oxygen carrier allows for the materials of enhanced activity or stability
during chemical looping process. However, the lack of mechanical understanding of the …

In this paper we report on the use of CoFe 2 O 4 spinel for the chemical loop processing for
hydrogen production from methanol as the reducing species. The process is based on two …
