The invention relates to a process for the production of hydrogen peroxide comprising: providing an electrochemical cell comprising an anode and a cathode; contacting the cathode with an electrolyte comprising at least one organic mediator dissolved in an at least partially organic continuous liquid phase comprising an at least partially organic salt and a neutral co-solvent, said salt comprising at least one kind of organic cation and/or organic anion, said continuous liquid phase having an electrical conductivity under process conditions of at least about 0.1 S/m; reacting the organic mediator at the cathode to form at least one reduced form of the mediator; and, reacting the at least one reduced form of the mediator with oxygen to form hydrogen peroxide.
