1. A method for the electrochemical production of hydrogen in an electrochemical cell comprising:
an anode;
a cathode; and
a liquid electrolyte comprising an ionic hydrogen carrier;
wherein the electrochemical cell is operated under conditions such that hydrogen gas is produced from the ionic hydrogen carrier at the cathode;
wherein nitrogen gas is produced from the ionic hydrogen carrier at the anode; and
wherein the electrolyte comprises at least 90 wt % of the ionic hydrogen carrier.
