A sensitivity analysis was also performed for IPA ECD and the same trend of acetone ECH was observed, as seen in Figure . The carbon footprint decreased in order of magnitudes with the increase of IPA concentration from 0.05 to 10M. With water as the only electrolyte, 0.05M IPA exhibited a carbon footprint of 178 kgCO2/kg H2 released that decreased to 2kgCO2/kg H2 released at 10M IPA concentration. In 1M KOH electrolyte, the carbon footprint also significantly decreased from 1290 to 3 kgCO2/kg H2 released when IPA concentration was increased from 0.05 to 10M. IPA and alcohols in general have shown promising performances on ECD reactions in alkaline conditions and offer room for use of a wide range of catalysts. However, the tradeoffs with the high carbon footprint it comes with on overall IPA ECD should also be considered when developing ECD processes for LOHC cycling. Further developments and studies on using high substrate concentrations in ECD will also help in the development of ECD in the LOHC cycling process.
