VFBs (Vanadium Flow Batteries) are a type of energy storage technology that offers competitive advantages in key emerging markets, including remote mine sites and data centres. They are ideal for hot climates due to their ability to cycle efficiently at higher temperatures without thermal runaway risk or degradation.
The Core ESG Action
VFBs have been proposed as a solution to reduce Scope 1 emissions by 12% in 2026, maintain zero Low-Tech Indirect (LTIs) over 12 months, and establish a board sustainability compliance committee. Additionally, they are being explored for use in contracted energy frequency control, energy arbitrage, offtake ancillary services, renewable energy, capacity markets grid services, and integration.
ESG Themes and Impacts
The unique attributes of VFBs position them for use in key emerging BESS (Battery Energy Storage System) use cases, including data centres and remote mine sites. Their advantages over established BESS technology include duration, no thermal runaway risk, minimal degradation, and full depth of discharge.
Governance and Regulatory Alignment
VSUN Energy has taken strategic actions to position itself for VFB BESS deployment in Australia, differentiating through its VFB architecture (Lumina), VFB project experience, and AVL’s vanadium supply-chain capability (V-NOMAD and the Australian Vanadium Project). This positions the company to target a growing pipeline of long-duration energy storage opportunities.
Forward Commitments
VFBs are being explored for use in contracted energy frequency control, energy arbitrage, offtake ancillary services, renewable energy, capacity markets grid services, and integration. The company has also proposed build-own-operate (BOO) BESS platforms, such as VSUN Energy’s Lumina platform.
