The increasing share of renewables such as solar and wind in energy supply challenges the grid stability since the generation often does not match demand. Redox flow batteries (RFBs) are considered as highly promising candidates for large-scale buffering systems to tackle the supply/demand imbalance. However, comprehensible sustainability in the energy system should also be based on renewable materials rather than the currently used non-renewable and often even toxic ones in commercial RFBs.<br/>Recent research deals with the synthesis of quinones as active materials for RFBs in order to tune price, stability and redox-potentials. Here, we present our latest results of the investigation of bio-based active materials with applications in stationary energy systems in redox flow batteries. The electrochemical properties of the battery as well as its performance under real conditions will be presented. Using bio-based active materials, coulomb efficiencies between 94 and 99% per cycle can be retained for 250 cycles.<br/>
