Vanadium Flow Battery

VFB is a promising storage technology where chemical reactions of reduction and oxidation lead to storing energy.

  • Safety

    VFB stores energy with stable chemistry based on an aqueous electrolyte. It is non-flammable and non-explosive, resulting in the safest energy storage ever.

  • Long lifetime

    VFB storage has no degradation regardless of deep cycle operations. It can perform 20,000+ cycles in over 20 years of operation retaining its original energy capacity.

  • Scalability

    Power and energy components decoupled in the system allow you to deploy completely scalable energy storage. With the unique scalability, our systems meet your specific needs for power and energy capacities.

  • Long duration

    VFB can deliver the energy across 4-12 hours and easily expand the energy capacity by simply adding more electrolytes to the existing system. With this feature, it can expand capacity as needed even in the middle of lifespan.

VFB consists of ‘Stack’ for Power and ‘Electrolyte’ for Energy. The flow of positive and negative electrolytes goes through an electro-chemical process of oxidation and reduction. Since this electro-chemistry is basically surface reactions having no volume changes on electrodes, no degradation is made even after repeated cycles of charging and discharging. With H2’s proprietary flow battery technology, more renewables can be added to the grid.
