Scalability - decoupled Power and Energy Capacity
Redox Flow Batteries (RFBs) offer exceptional scalability, making them a game-changing solution for energy storage at various levels—from small-scale applications to grid-level deployment. Their unique architecture allows for independent scaling of power and energy capacity, providing unmatched flexibility compared to conventional battery technologies. Unlike traditional batteries, where power and energy are intrinsically linked, flow batteries have modular and flexible design and store energy in external liquid electrolyte tanks. This means that energy capacity can be increased simply by enlarging the electrolyte tanks without modifying the core electrochemical stack. Power output can be adjusted by adding more or larger stacks, optimizing the system for specific needs.
Long-duration storage
Flow Redox Batteries (FRBs) are uniquely suited for long-duration energy storage (LDES) due to their ability to store and discharge electricity over extended periods—ranging from several hours to multiple months. Unlike traditional battery technologies, which are optimized for short bursts of power, FRBs provide a stable, scalable, and cost-effective solution for prolonged energy delivery. Solutions
Long cycle life
Flow batteries have the potential for a longer cycle life compared to lithium-ion batteries. Since flow batteries use liquid electrolytes, they experience minimal degradation over time, resulting in a prolonged lifespan. Lithium-ion batteries have a limited cycle life and gradually degrade over time, especially with deep discharge and fast charging. In every charge/discharge cycle, part of the active materials are transformed into dendrites - therefore, with every cycle, the storage capacity decreases (some common grid storage batteries lose 20÷40% of their capacity during the first decade of service; efficiency decreases, too). This is not the case with the flow batteries - they degrade as a result of ageing of materials, irrespective of how often the flow battery was charged/discharged. For this reason, the lifetime of flow battery is expressed in years. The lifetime of the membrane stacks (the part that degrades over time) is around 15÷20 years. After that period there is no necessity to replace the complete battery (as would be the case with a lithium-ion battery). Instead, only the membrane stacks are exchanged. These give the flow battery a second life at marginal additional costs.
Levelized Cost of Storage
Levelized Cost of Storage (LCoS) is a key metric used to compare the economic viability of different energy storage technologies. It accounts for the total lifetime costs of a storage system—including capital expenses, operational costs, efficiency losses, and cycle life—divided by the total amount of energy stored and discharged over its lifetime.
Flow Redox Batteries (FRBs) stand out as a cost-effective solution for long-duration energy storage due to their long lifespan, low maintenance, and independent scalability of power and energy capacity.
Deep discharge capability
When compared with li-ion, the flow battery has a depth-of-discharge of 100%, meaning that it can use the full capacity from 0 to 100% for charging/discharging without affecting the battery’s lifetime. Applying a 100% depth-of-discharge with a li-ion battery would cause a considerably shorter lifetime. To maximize the number of (dis)charge cycles, li-ion batteries are usually used between 10 and 90% of their full capacity – meaning that in practice only 80% of the purchased capacity is actually used. Generally, flow batteries can be discharged completely without compromising their performance or cycle life. They are capable of sustaining long-duration discharges, making them suitable for applications requiring continuous and prolonged energy delivery.
