  text: We show the synthesis of a redox‐active quinone, 2‐methoxy‐1,4‐hydroquinone
    (MHQ), from a bio‐based feedstock and its suitability as electrolyte in aqueous
    redox flow batteries. We identified semiquinone intermediates at insufficiently
    low pH and quinoid radicals as responsible for decomposition of MHQ under electrochemical
    conditions. Both can be avoided and/or stabilized, respectively, using H 3 PO
    4 electrolyte, allowing for reversible cycling in a redox flow battery for hundreds
    of cycles.
