Iron oxide cycle

The iron oxide cycle (Fe₃O₄/FeO) is a two-step thermochemical cycle proposed for use for hydrogen production.^[1]

Process description

The thermochemical two-step water splitting process uses redox systems. The two iron oxide cycles under research^[2] are:

• Mn_0.5Zn_0.5Fe₂O₄ + yH₂O→Mn_0.5Zn_0.5Fe₂O_4+y + yH₂

• Mn_0.5Zn_0.5Fe₂O_4+y→Mn_0.5Zn_0.5Fe₂O₄ + y/2O₂

The temperature level is realized by using a solar power tower and a set of heliostats to collect the solar thermal energy.
