Electric power generation from natural resources is a promising method to reduce carbon dioxide emission by combustion of fossil fuel. Arid land has wide area and plenty of natural resources for energy production. However output power of natural energy resource is not stable in general. For example, electric power of photovoltaic cell alters with the daily cycle of solar radiation. So, large-scale energy storage is essential facility for practical use of natural energy as primary resource. Redox flow battery (RFB) is one of the most expected battery systems for such storage. In RFB, redox chemical pair is solved in electrolyte and emits or accepts electron from electrodes to generate electric current. The solutions of active material are circulated between the battery cell and reservoir, and battery capacity is proportional to the liquid amount in reservoir tanks. RFB utilizing vanadium ions for redox pair has been studied extensively and some of experimental plants are in practical operation. However, organic materials can also be explored for more safety and cost efficiency. As candidates of such redox pair, different kinds of organic molecules, produced by plants or other biological body, are under investigation. In this study, molecular species related to energy metabolism and their derivatives were tested as active materials for organic RFB.
