reduce the energy input, the utilization of carbon (coal), alcohols (hydrocarbon solution), and organic solution (glycerol, formic acid, ethylene glycol, etc.) with co-electrolysis of water has been proposed as a viable option. The carbon/hydrocarbon assisted water electrolysis (so-called CAWE) process for hydrogen generation would perform this operation in a single electrochemical reactor. This system energy balance can be required only around 40% electric input with 60% coming from the chemical energy of carbon or hydrocarbon. This process utilizes solid coal/carbon particles or powder as fuels dispersed in acid/alkaline electrolyte in the form of slurry and the carbon contained source co-assist in the electrolysis process as following theoretical overall reactions: Carbon/Coal slurry (C + 2H2O) → CO2 + 2H2 E′ = 0.21 V (reversible voltage) / E′ = 0.46 V (thermo-neutral voltage) or Carbon/Coal slurry (C + H2O) → CO + H2 E′ = 0.52 V (reversible voltage) / E′ = 0.91 V (thermo-neutral voltage) Thus, this CAWE approach is that the actual cell overpotential can be significantly reduced to below 1.0 V as compared to 1.5 V for conventional water electrolysis. Electrocrystallization A specialized application of electrolysis involves the growth of conductive crystals on one of the electrodes from oxidized or reduced species that are generated in situ. The technique has been used to obtain single crystals of low-dimensional electrical conductors, such as charge-transfer salts and linear chain compounds. Electrolysis of Iron Ore The current method of producing steel from iron ore is very carbon intensive, in part to the direct release of CO2 in the blast furnace. A study of steel making in Germany found that producing 1 ton of steel emitted 2.1 tons of CO2e with 22% of that being direct emissions from the blast furnace. As of 2022, steel production contributes from 7 to 9% of global emissions. Electrolysis of iron can eliminate direct emissions and further reduce emissions if the electricity is created from green energy. The small-scale electrolysis of iron has been successfully reported by dissolving it in molten oxide salts and using a platinum anode. Oxygen anions form oxygen gas and electrons at the anode. Iron cations consume electrons and form iron metal at the cathode. This method was performed a temperature of 1550 °C which presents a significant challenge to maintaining the reaction. Particularly, anode corrosion is a concern at these temperatures. Additionally, the low temperature reduction of iron oxide by dissolving it
