OUR TECHNOLOGY

AVESS Energy is the 50% majority shareholder of South Korean VRFB R&D Company KORID Energy Co. Ltd.

KORID has delivered a highly efficient 25kW VRFB stack, which has the potential to outperform the stacks of Tier 1 manufacturers.

The 25kW stack has been meticulously engineered to be lighter and more compact while eliminating leakage and improving assembly efficiency.

Market Advantages

Lifespan

  • VRFBs have significantly longer lifespans compared to Lithium-ion (Li-ion) energy storage systems (ESS).
  • VRFBs are capable of cycling more than 20,000 times over a 20+ year lifespan – with minimal performance degradation.
  • L-ion batteries can expect to see a performance degradation of 50% between 500 and 5,000 cycles.
  • VRFBs display superior capacity retention and reduced performance degradation – over time – compared to Li-ion ESS.
  • For example, VRFBs can be charged or discharged for extended periods with little to no effect on future performance.

Scalability

  • VRFBs are highly scalable.
  • VRFBs can be scaled up by simply expanding the size of the electrolyte tanks or by stacking additional modules next to each other.

Sustainability

  • VRFBs are 100% recyclable.
  • Vanadium electrolytes in a VRFB undergo minimal performance degradation over their energy storage lifecycle.
  • At end-of-life, vanadium electrolytes can either be re-deployed into new VRFBs or be extracted and re-purposed.

Safety

  • Vanadium electrolytes are an acidic, aqueous (water-based) solution containing no organic solvents. There is no risk of fire or explosion.
  • Vanadium content is highly diluted, meaning the electrolytes are essentially non-toxic.

Abundance

  • Vanadium comprises 0.02% of the Earth’s crust – more than 10 times that of lithium (0.002%).
  • With the world’s 3rd biggest vanadium reserve – behind China and Russia – Australia is poised to become a Tier 1 global producer once vanadium goes into production.
  • Lithium supply is projected to fall by 2030 with demand expected to outstrip supply – due to the growth in EV uptake.
