7. Concluding remarks and perspectives Flow batteries are regarded as one of the most promising large-scale energy storage technologies because of their site-independency, decoupling of power and energy, design flexibility, long cycle life, and high safety.
The most commonly used porous electrode material in flow batteries is graphite felt, which was primarily developed for thermal insulation in the high-temperature range. As a diffusion electrode, the material offers the necessary properties to improve the performance of the system.
Redox flow batteries (RFBs) have emerged as a promising solution for large-scale energy storage due to their inherent advantages, including modularity, scalability, and the decoupling of energy capacity from power output. These attributes make RFBs particularly well-suited for addressing the challenges of fluctuating renewable energy sources.
Requirements of electrolytes In a flow battery, the electrolytes serve as the working solution carrying redox active substances, some vital parameters such as open circuit voltage (OCV), conductivity, viscosity, concentration, etc. will have great impacts on the battery.
The flow battery is going to be connected to a local wind farm and will be capable of storing energy for three hours. The overarching aim of the project is the integration of larger shares of renewable energy by renewable shifting, to avoid or at least postpone grid extensions.
Just for all-vanadium flow batteries the power density may vary between 50 and more than 500 mA cm −2 with an energy density of about 30 Wh L −1, while zinc-polyiodide flow batteries have even reached 167 Wh L −1 in a developmental stage 43, 44.
