The quantity of hydrogen gas fed to the system (S-3) was 2.62kg/hr. The carbon footprint of hydrogen production from water electrolysis using wind sourced renewable electricity is 0.7kgCO2/kg H2, which is an estimated average from literature reports. The carbon footprint of hydrogen production from water electrolysis was obtained assuming 50kwh is consumed per kg H2 in a typical water electrolyzer operating at 80% efficiency. Using non-renewable electricity obtained from natural gas, the carbon footprint for H2 production by water electrolysis is 22kgCO2/kg H2. This carbon footprint value is also similar to the one reported by Parkinson, et al. The pure hydrogen gas feed stream (S-2) was mixed with recycled hydrogen (S-9) before being introduced to the reactor inlet as stream S-4.
