Aspen Plus v12.1 software was used to model the thermochemical and distillation processes with acetone/IPA as the LOHC couple. The acetone hydrogenation and IPA dehydrogenation reactions have been widely reported in various application making the acetone/IPA couple being used as the LOHC couple model. Moreover, the comprehensive thermodynamic database for acetone and IPA in Aspen Plus motivated the use of the acetone/IPA pair as a straightforward model approach. The property methods used in Aspen software were the Soave-Redlich-Kwong (SRK) and non-random two-liquid model (NRTL) for the thermochemical reactors and distillation simulations, respectively. Assumptions made include: i) molecular H2 for the thermochemical and hybrid processes was obtained from water electrolysis while the electrochemical process generated protons in-situ, ii)1kmol/hr of LOHC molecule was fed into the reactor, iii) natural gas was the fuel source for heating the streams, reactors, and distillation reboilers, iv) non-renewable electricity is sourced from natural gas, v) carbon footprint for the production of starting materials (either acetone or IPA) was not considered since it is the same for all processes, vi) carbon footprint of water as solvent or reactant is ignored, vii) no joule heating of the electrochemical reactor occurred from ohmic losses, viii) electrochemical reactions are running at thermodynamic redox potentials, ix) pumps and compressors are operated by electricity and x) the final use of H2 is the same for both cycling methods.
