AVL advances its technology platform targeted at lowering the delivered cost of electrolyte

KEY POINTS

• AVL is progressing the development of its V-NOMAD™ electrolyte production technology platform, which is intended to reduce the delivered cost of vanadium electrolyte for gigawatt-hour scale vanadium flow battery (VFB) applications

• The technology platform incorporates a range of internally developed design features and process approaches with the objective of reducing electrolyte logistics and storage requirements, supporting a range of vanadium feedstocks and reducing VFB commissioning costs, while maximising Australian local content

• The Company has applied for Industry Attraction Fund support to progress design and construction and is targeting the proposed Kalgoorlie VBESS project1 as a potential initial deployment, with further applications possible across AVL-developed projects and third-party VFB installations

• AVL has appointed Sedgman to support detailed engineering, modularisation and execution readiness planning for the technology platform as it progresses toward potential deployment

Australian Vanadium Limited is pleased to advise that it is progressing the development of its V-NOMAD™ technology platform, a vanadium electrolyte production technology which incorporates internally developed know-how, intended to support lower delivered cost of vanadium electrolyte for gigawatt-hour (GWh) scale VFB applications.

The technology platform forms part of AVL’s broader strategy to develop a vertically integrated vanadium mining, processing, electrolyte production and VFB deployment business. It is being developed with the objective of addressing cost, logistics and deployment considerations associated with large-scale VFB projects, including applications in remote, off-grid and high-temperature environments, as well as behind-the-meter applications such as data centres and industrial energy systems.

Traditional centralised electrolyte production models typically involve significant logistics, storage and working capital requirements at GWh scale, particularly for remote or staged project deployments.

The Company’s Chief Executive Officer, Graham Arvidson comments, “The development by AVL of the V-NOMAD™ technology platform is a significant advancement in our long-term strategy to support the deployment of utility-scale vanadium flow batteries as long-duration energy storage and other use cases, such as AI data centres, continue to gain momentum globally.

“At gigawatt-hour scale, electrolyte logistics and storage requirements are a material component of overall project cost and complexity. V-NOMAD™ is being developed to address this challenge directly by enabling electrolyte production to occur at or near the point of use.

“The technology is being developed to effect more efficient production and delivery of electrolyte by reducing logistics and handling requirements at scale across a wide range of applications and operating environments, particularly in remote locations.

“The progression of our V-NOMAD™ technology platform is aligned with our broader development activities, including the proposed Kalgoorlie VBESS project, which if awarded to AVL, would provide an opportunity to utilise the technology in a large-scale application.”

Through a program of testing, engineering design and feasibility work, AVL is progressing the development of a flexible and scalable electrolyte production technology incorporating a range of internally developed design features and process approaches. These include aspects of process flowsheet design, feedstock flexibility, quality management, deployment and logistics strategy, and final electrolyte product format. The technology platform is intended to convert vanadium feedstocks into finished electrolyte product at or near the point of use with the objective of reducing electrolyte logistics and storage requirements, maintaining product quality standards, supporting a range of vanadium feedstocks, reducing VFB commissioning costs and seeking to maximise Australian local content.

A key feature of the technology platform is its architecture which is being developed to enable deployment at or near VFB installation sites (see Figure 1). This approach is intended to reduce electrolyte logistics, handling and storage requirements that may otherwise impact delivered electrolyte costs at scale. The deployment model is being designed to support utilisation of the platform across multiple projects with efficient scalability to meet the needs of specific projects.

The technology platform is being developed with the objective of supporting lower electrolyte delivered cost while maintaining product quality standards. It is also intended to support flexibility in vanadium feedstock selection and to maximise Australian local content, consistent with AVL’s commercial objectives and broader industry and policy settings.

The ability to utilise the technology platform across multiple projects is intended to support VFB deployments in a range of operating environments, including remote mining regions, hot climates, off-grid power systems, data centres and behind-the-meter energy applications. This is intended to position AVL to respond to increasing demand for long-duration energy storage, noting that further development and validation will be required.

The technology platform is being developed with potential application across both AVL-developed projects and third-party VFB installations, subject to further development, validation and commercial arrangements.

To progress the next phase of development, AVL has appointed Sedgman Pty Ltd2 (Sedgman) to support detailed engineering and execution readiness planning for the technology. Sedgman’s scope includes advancing the technology toward a level of definition suitable for potential construction and deployment, with a focus on scalability, repeatability and disciplined project delivery.

The Company has applied for support under the Industry Attraction Fund to progress the design and construction of an initial large-scale unit using the technology platform and is targeting the proposed Kalgoorlie VBESS project as a potential initial deployment. This approach is intended to align with Australian and State Government objectives to localise critical minerals value chains and support the deployment of long-duration energy storage infrastructure.

The Company continues to pursue appropriate intellectual property protection strategies in support of its development program. This includes the protection of its know-how and, where appropriate, the filing of patent applications that are progressing in the ordinary course. There is no certainty that any patent application will be granted or, if granted, that it will provide commercially meaningful protection.
