No degradation and long lifespan
The capacity of VRFBs does not fade away by charging or discharging the system. This results in practically unlimited cycles over 20 years of use.
Easy to recycle
Since the electrolyte does not degrade by being used its easy to upcycle, resycle or in some cases imidatly reuse it in new systems.
Non-flammable
Most of the system weight consits of liquid non-flammable materials, making the system robust against fire - even external flames.
Economical
VRFBs lifespan is 2-4 times longer than most competing technologies. In addition, no capacity fade reduces to the cost of services and mainainance. This combination gives VRFBs one of the lowest lifetime costs (LCOS).
Customizable
The power and capacity components of the system are completely independant from each other. If you need more power, you install more battery stacks, if you need more capacity, you install bigger tanks with elecotrlyte. The overall system cost per kwh is lower the more capacity is included. Therefore most flow batteries are designed for 4, 8, 12 hours or more.
No self-discharge
VRFBs have practically no self-discharge, enabling new opportunities for long-duration or even seasonal energy storage.
