Australian Vanadium Gets AICIS Certificate for Electrolyte Production
Key Takeaways
- AVL's AICIS certificate (CA10138) allows up to 27,509 tonnes a year of sulfuric acid, vanadium(3+) salt at up to 35% in aqueous solution, clearing a regulatory step for industrial-scale electrolyte production.
- AVL estimates that limit would support roughly 2.5 GWh of deployed vanadium flow battery capacity, though the figure rests on its current formulation and conversion assumptions.
- A second AICIS certificate covers vanadium trioxide (V₂O₃), a possible raw material in AVL's electrolyte process.
- The certificate gives AVL a pre-listing head start of up to five years over parties that haven't met AICIS requirements, though the announcement does not describe it as exclusive.
- The expansion remains proposed, with no disclosed funding, timelines, capital costs or revenue figures, so the commercial payoff is still unproven.
AICIS certificate supports industrial-scale vanadium electrolyte production
Australian Vanadium Limited (ASX: AVL) has received an assessment certificate from the Australian Industrial Chemicals Introduction Scheme (AICIS) under the Industrial Chemicals Act 2019 (Cth), covering a key industrial chemical component of vanadium electrolyte. The announcement was dated 6 October 2026.
The company describes the certificate as establishing an “important Australian regulatory pathway” supporting its proposed expansion to industrial-scale production of vanadium electrolyte for use in vanadium flow batteries (VFBs). A VFB stores energy in liquid electrolyte, so the electrolyte is the core consumable of the technology.
For investors, the certificate addresses a regulatory step in AVL’s midstream scale-up. The announcement does not say the expansion is funded, approved or under construction.
Separately, AVL has also received an AICIS assessment certificate for vanadium trioxide (V₂O₃), which may be used as a raw material in its vanadium electrolyte production process.

What the certificate authorises
Scope and limits
The certificate lets AVL bring the assessed chemical into Australia, within defined boundaries. Per AICIS Assessment Statement CA10138, the key details are:
- Assessed chemical: sulfuric acid, vanadium(3+) salt (3:2) (CAS 13701-70-7)
- Assessed limits: up to 27,509 tonnes/year and up to 35% in aqueous solution
- Authorisation: AVL may introduce the chemical by import or manufacture in Australia within the specified annual limit and subject to the conditions in the certificate
- Scope of use: as a component of electrolyte for industrial-scale VFB applications, subject to applicable worker health and safety and environmental controls
In plain terms, the certificate sets a ceiling on volume and concentration, and any use has to stay inside those conditions.
Capacity implication
AVL estimates the annual introduction limit would support production of sufficient electrolyte for approximately 2.5 GWh of deployed VFB capacity. That estimate is based on AVL’s current electrolyte formulation and conversion assumptions, so it may shift if those assumptions change.
| Item | Detail | Investor relevance |
|---|---|---|
| Annual introduction limit | Up to 27,509 tonnes/year | Sets the volume ceiling for the assessed chemical |
| Concentration | Up to 35% in aqueous solution | Defines the form in which the chemical was assessed |
| Estimated VFB capacity supported | Approximately 2.5 GWh (AVL estimate, based on current formulation and conversion assumptions) | Indicates the scale of VFB deployment the limit could support |
Graham Arvidson, Chief Executive Officer
“This is an important regulatory milestone for AVL’s midstream business. We expect this regulatory pathway to support our midstream scale-up strategy as we continue to expand AVL’s vanadium electrolyte capability to match the scale of vanadium flow battery projects taking shape within VSUN Energy’s pipeline of opportunities…”
How do AICIS certificates work and why does it matter?
AICIS regulates the introduction (import or manufacture) of industrial chemicals into Australia. An assessment certificate allows the holder to introduce a chemical before it is publicly listed on the Australian Inventory of Industrial Chemicals.
Under the framework described by AVL:
- During the pre-listing period, only certificate holders and persons covered by an assessment certificate can introduce the assessed chemical.
- Another party may apply for its own assessment certificate or seek to be covered by an existing certificate in accordance with AICIS requirements.
- If the certificate remains in force, the assessed chemical must generally be listed on the Australian Inventory of Industrial Chemicals once five years have elapsed from issue, subject to the statutory provisions permitting earlier listing.
What that tells you is that, during the pre-listing period, AVL holds a regulatory head start over parties that have not yet satisfied AICIS requirements. The announcement does not describe this as an exclusive right.

Strategic fit and what comes next
AVL’s vertical integration strategy covers processing vanadium to high purity, manufacturing vanadium electrolyte, and working with VSUN Energy, its 100% owned renewable energy and energy storage subsidiary, as it develops projects based on renewable generation and VFB energy storage. The certificate sits in the electrolyte step of that chain.
The electrolyte step sits alongside the Tenindewa processing facility, which is designed to convert mined ore into high-purity vanadium products and which recently had conditions on its development approval varied by the Western Australian Planning Commission.
At the front of the chain is the Australian Vanadium Project at Gabanintha, reported at 395.4Mt at 0.77% vanadium pentoxide (V₂O₅). That includes a high-grade zone of 173.2Mt at 1.09% V₂O₅, reported in compliance with the JORC Code 2012 (ASX announcement dated 7 May 2024).
The next step the announcement points to is scaling the midstream business to match the VFB projects within VSUN Energy’s pipeline of opportunities. It does not disclose timelines, capital costs or revenue figures, so the commercial impact of the certificate remains to be shown.
