The VCHARGE± battery system technology has been proven safe for use in urban applications in proximity to adjacent structures and densely populated areas due to its inherent non-flammability.
The VRFB is one of the leading technologies in long-duration energy storage applications because it is intrinsically safe, with no fire risk from thermal runaway.
Thermal runaway occurs when current flowing through a battery on charge or overcharge causes temperatures to rise, further increasing the current output and temperature, which eventually results in fire. Thermal runaway is a significant risk in solid-state batteries, such as lithium-ion applications.
The electrolyte solution used in the VRFB is non-volatile – it is neither flammable, nor explosive as a result of its high water content which offers a very high degree of operational safety compared to other battery energy storage systems. This inherent non-flammability of the water-based electrolyte used in VRFBs makes them ideal for deployment in densely populated areas, airports, schools and wooded areas where mitigating the safety risk caused by fire and smoke is paramount.
Safety is essential for energy storage.

Grid-scale lithium-ion batteries are an unsafe compromise.
