Voltage normally used in electrolysis is a minimum of 1.23v
With this electrode, it is 1.07v.....

Researches on electrolysis have attracted great attentions in recent years as a promising technology to convert renewable energy into chemical energy, and many studies on water electrolysis, (1,2) CO2 electroreduction, (3−5) N2 electroreduction, (6,7) and so on (8−13) are addressed to develop a sustainable society. Electricity derived from renewable energy can be used directly to operate these electrolyzers. In addition, the rates of electrochemical reactions would be easily controlled by the electrolysis current in accordance with the energy supply situation; therefore, electrolyzers can follow daily and seasonal fluctuation of renewable energy unlike the conventional thermal reactions. In recent years, it is known that electrohydrogenation of toluene (TL) to methylcyclohexane (MCH) is one of the promising technology as the hydrogenation process in an organic hydride hydrogen storage system. (14−32) Water is oxidized on an anode (eq 1), and TL is reduced to MCH with electrons and protons on a cathode (eq 2) which is widely known as a transportable hydrogen carrier. (33−36) As presented by eq 3, the theoretical electrolysis voltage of the reaction (1.07 V) is lower than that of the water electrolysis (1.23 V). Thus, the direct electrohydrogenation process has significant advantages in energy conversion efficiency for the hydrogenation of TL to MCH to compare with a conventional 2-step hydrogenation process, which consists of the water electrolysis and the catalytic hydrogenation of TL. (16) In accordance with the demand of energy, hydrogen is extracted by a catalytic dehydrogenation of MCH to TL and used as an energy source. (33−36)
