Electrolyte tank costs are an overlooked factor in flow battery economics

Nature Energy· Volume 10· Issue 1

Abstract

The economic feasibility of flow battery systems has been a focal point of recent research, yet the cost of electrolyte tanks is frequently overlooked in technoeconomic analyses. This study questions the prevailing assumption that tank costs are negligible in flow battery designs, revealing their significant influence on system economics. Based on price data obtained from globally distributed tank manufacturers, it is evident that tank costs are often grossly underestimated or entirely excluded in most published models. Simple calculations suggest that electrolyte tanks could account for as much as 40% of the energy-related costs (electrolyte and tank) in MWh-scale flow battery systems. To address these cost challenges and support broader market adoption, the study emphasizes the importance of component standardization and the advancement of high-voltage chemistries.
