Abstract: The present invention relates to the manufacture of benzoquinones, in particular to the manufacture of a potassium salt of a benzoquinone, such as 2,5-dihydroxy-1,4-benzoquinone di-potassium salt. The potassium salt of a benzoquinone is obtained by oxidation of a hydroquinone using potassium hydroxide and hydrogen peroxide, which results in an efficient process with high yields.

Abstract: The present invention relates to an aqueous energy storage system, comprising a half-cell containing an aqueous solution of at least two redox-active compounds (RACs) and one or more insoluble preferably organic energy storage material(s). Moreover, the use of such a half-cell as negative electrode in redox-flow battery application is described.
