OUR TECHNOLOGY

AVESS Energy owns and develops world-class VFB stack technology.

With its high operating performance, longevity and circular-economy principles, our patented 25kW VFB stack is designed to outperform the competition.

The business has developed a highly efficient 25kW VFB stack with the potential to surpass the stacks of Tier 1 manufacturers.

Engineered to be more compact, the 25kW stack neutralises leakage risks, while maximising assembly efficiency.

Already deployed to 1MW in South Korea, our stack technology has been independently verified and demonstrates flexibility to scale.

Market Advantages

VFBs offer several advantages over Li-ion ESS such as:

Lifespan

  • VFBs have significantly longer lifespans compared to Li-ion ESS.
  • VFBs can complete more than 20,000 cycles over a lifespan of 20 years with minimal performance degradation.
  • Li-ion batteries can experience up to 50% performance degradation after approximately 500 to 5,000 cycles.
  • VFBs display superior capacity retention and reduced performance degradation over time over Li-ion ESS.
  • For example, VFBs can be charged or discharged for extended periods with little to no effect on future performance.

Scalability

  • VFBs are highly scalable.
  • VFB energy capacity can be increased by expanding the electrolyte tanks, while power output can be increased by adding stack modules.

Sustainability

  • The vanadium electrolyte experiences minimal performance degradation.
  • It can be reused indefinitely, recovered or repurposed, supporting circular economy principles.

Safety

  • The vanadium electrolyte is an acidic, aqueous solution that contains no organic solvents and is non-flammable, eliminating the risk of electrolyte combustion.
  • The vanadium is in the aqueous electrolyte is at a relatively low concentration.

Abundance

  • Vanadium comprises approximately 0.02% of the Earth’s crust, compared with approximately 0.002% for lithium.
  • Australia has the world’s 3rd largest vanadium reserve, behind China and Russia, and is poised to become a Tier 1 global producer once domestic production begins.
  • Lithium supply is projected to tighten by 2030 with demand expected to outstrip supply, because of growth in EV uptake.
