Recent interest in hydrogen as an alternative fuel for lowering carbon emissions is funding the exploration of new ways for producing this molecule in a clean way. Iron oxides can be used within a process of chemical looping to produce hydrogen when switching from an oxidation state to another one. More specifically, they can lose oxygens at extremely high temperature in an inert atmosphere. The reaction can be helped by adding a gas to the reactor, so that it can happen at a temperature level reachable in a solar dish concentrator. The optimization and well-functioning of the solar facility is key for running the reaction.
