Practical interest in redox flow batteries has arisen in recent decades as a result of intensive development in the field of alternative energy (such as solar and wind) and the control of peak loads in industrial electrical networks. It turned out that large-scale energy storage systems used to compensate fluctuations in the process of solar and wind generation of energy in the production of electric vehicles and power supply systems for large households, are more profitable when working on redox flow batteries. Firstly, they are easy to scale, and secondly, the energy stored in such batteries is cheaper. In recent years, the interest of researchers in the redox behavior of simple and substituted quinones and anthraquinones used as potential components of electrochemical energy storage systems has grown significantly. The main advantages of organic redox systems are scalability, kinetic advantages over the used redox systems based on inorganic substances, reconstructability (a wide possibility of changing electrochemical and chemical properties by introducing various functional groups into organic molecules) and environmental safety. Therefore, in this work, the electrochemical behavior of some promising organic systems based on quinone, anthraquinone and their analogs to be used as redox systems of flow batteries was studied using the method of cyclic voltammetry.

Redox flow battery technology has been known since the 1970s. Their low specific characteristics have been of interest for a long time. Practical interest has arisen in recent decades because of the intensive development of alternative energy (such as solar and wind) and the regulation of peak loads in industrial networks. It turned out that large-scale energy storage systems used for compensation of fluctuations in the generation of energy by the sun and the wind, while producing electric vehicles and power supply systems for large households, are more profitable when they work on flow redox batteries. Firstly, they are easily scalable, and secondly, the energy stored in such batteries is cheap. Since the expansion of the scope of practical use of flow batteries has taken place in recent years, researchers continue to work on increasing the economic efficiency of flow batteries and on the search for more efficient redox systems. One of these areas is the use of cheaper redox systems of organic nature, in particular, quinone, anthraquinone and their analogs. Their high water solubility, well-separated oxidation-reduction potentials, which practically eliminate water splitting, their stability, safety, and low cost on a scale of mass production are the most important characteristics for new aqueous organic electrolytes. So far, organic redox flow batteries are still inferior to vanadium and other inorganic redox batteries in terms of their operational parameters. This drawback hinders their development on industrial scale. However, the results shown in this review can help scientists to improve them and commercialize in the future.

The utilization of intermittent renewable energy sources needs low-cost, reliable energy storage systems in the future. Among various electrochemical energy storage systems, redox flow batteries (RFBs) are promising with merits of independent energy storage and power generation capability, localization flexibility, high efficiency, low scaling-up cost, and excellent long charge/discharge cycle life. RFBs typically use metal ions as reacting species. The most exploited types are all-vanadium RFBs (VRFBs). Here, we discuss the core components for the VRFBs, including the development and application of different types of membranes, electrode materials, and stack system. In addition, we introduce the recent progress in the discovery of novel electrolytes, such as redox-active organic compounds, polymers, and organic/inorganic suspensions. Versatile structures, tunable properties, and abundant resources of organic-based electrolytes make them suitable for cost-effective stationary applications. With the active species in solid form, suspension electrolytes are expected to provide enhanced volumetric energy densities.

Energy storage systems are expected to play a fundamental part in the integration of increasing renewable energy sources into the electric system. They are already used in power plants for different purposes, such as absorbing the effect of intermittent energy sources or providing ancillary services. For this reason, it is imperative to research managing and sizing methods that make power plants with storage viable and profitable projects. In this paper, a managing method is presented, where particle swarm optimisation is used to reach maximum profits. This method is compared to expert systems, proving that the former achieves better results, while respecting similar rules. The paper further presents a sizing method which uses the previous one to make the power plant as profitable as possible. Finally, both methods are tested through simulations to show their potential.

<div>Aqueous organic redox flow batteries have many appealing properties in the application of large-scale energy storage. The large chemical tunability of organic electrolytes shows great potential to improve the performance of flow batteries. Computational studies at the quantum-mechanics level are very useful to guide experiments, but in previous studies explicit water interactions and thermodynamic effects were ignored. Here, we applied the computational electrochemistry method based on ab initio molecular dynamics to calculate redox potentials of quinones and their derivatives. The calculated results are in excellent agreement with experimental data. We mixed side chains to tune their reduction potentials, and found that solvation interactions and entropy effects play a significant role in side-chain engineering. Based on our calculations, we proposed several high-performance negative and positive electrolytes. Our first-principles study paves the way towards the development of large-scale and sustainable electrical energy storage.</div>
