This project will investigate a novel Caustic Aqueous Phase Electrochemical Reforming (CAPER) process on an oxygenated hydrocarbon, liquid ethanol in this instance, to make strides towards the DOE’s long-term cost target of $4/kg of hydrogen at the dispenser. The proposed CAPER technology utilizes liquid ethanol and electricity, preferably from intermittent renewable sources, to produce high purity (99.99%) hydrogen at high pressure directly from the reactor. The CAPER technology also separates the produced CO2 from H2 in-situ by converting it to water-soluble HCO3-, leaving the gaseous hydrogen to bubble out of the caustic solution. The solution is then regenerated by removing high purity CO2 from the solution that can be sequestered or reused. The scientific and commercial impact of our paper is significant because the CAPER technology can offer a much simpler overall design of fuel reforming process by combining the reformer and CO2 capture units into one system, operate at much lower temperature (≤ 150 °C), and produce higher purity H2 (> 90%) at high pressure without using the external compressors. |
