A sensitivity analysis was also performed to investigate the effect of acetone concentration in ECH on the carbon footprint including separation. The analysis was performed at a constant acetone feed rate of 1kmol/hr and 84.8wt% IPA in the product stream. In Figure , the carbon footprint decreases as the concentration of acetone increases from 0.05M to 10M. The carbon footprint of 0.05M acetone was 410kg CO2 released per kg H2 stored while at 10M acetone 15.4kg CO2 was released per kg H2 stored. The decrease of CO2 is due to less water solvent used at higher concentrations and therefore requiring less energy for product separation. It should also be noted that, increasing acetone concentration affects the reaction performance. Green, et al. performed acetone ECH in a range of approximately 0.5-7M acetone and observed a slight decrease in conversion and current efficiency with increasing concentration at the concentration range studied. Further studies are needed for the development of ECH reactions to operate at high concentrations for LOHC applications to make them more viable. Additionally, the electrolyte/solvent lowers the hydrogen storage capacity of the LOHC couple limiting their transportation and mobility application viability. For instance, the hydrogen storage capacity of the acetone/IPA couple in its pure form is 3.3wt%. However, diluting the LOHC in electrolyte lowers the hydrogen storage capacity, as shown in Figure and). Decreasing the acetone or IPA concentration from 10M to 0.05M lowered the hydrogen loading/release capacity from 2.4 wt% to 0.01 wt%. Electrochemical dehydrogenation (ECD) of IPA to form acetone and hydrogen was also modelled as illustrated in Figure . IPA ECD has been demonstrated for direct alcohol fuel cell coupled with ORR at the cathode. IPA in water can be used as the anolyte feed. IPA ECD has also been performed under alkaline conditions (1M KOH) in a two compartment electrochemical cell coupled with HER on the cathode. Herein, IPA ECD was coupled with HER where IPA consumes hydroxyl ions to dehydrogenate and form acetone (reaction 4). On the counter side, hydrogen is obtained on cathode by HER (reaction 5) and releasing hydroxyl ions that transfer to the anode via anion exchange membrane. In this simulation, the carbon footprint of IPA ECD was demonstrated with and without 1M KOH in the electrolyte solution. IPA was fed to the reactor and did not require heating as the reaction was assumed to operate at 25 0 C and 0.1MPa. The overall IPA ECD at alkaline conditions with HER as the counter reaction theoretically undergoes spontaneous reaction (reaction 6). Therefore, an assumption was made where no electrical energy is required to drive the reaction. It is important to note that real-world conditions, including overpotentials, might require the application of voltage for the reaction, which was not accounted for in this model.
