Australian Vanadium and Alcoa to Study Vanadium Flow Battery Use at Alumina Refineries

Australian Vanadium Limited (AVL) has entered into a non-binding memorandum of understanding with Alcoa of Australia to assess the deployment of vanadium flow battery technology at Alcoa's alumina refineries, the company announced Tuesday.

Scoping Study Details

The agreement initiates a scoping-level study to examine the financial and technical viability of a large-scale vanadium flow battery (VFB) energy storage system. The collaboration will investigate installing a system to support Alcoa's energy-intensive operations in Western Australia.

The proposed battery system specifications include:

• A power capacity of 50 to 80 megawatts.
• A storage duration of 6 to 8 hours, with the potential for extension.

Roles and Responsibilities

Australian Vanadium, along with its wholly-owned subsidiary VSUN Energy Pty Ltd, will lead the study. Their responsibilities cover VFB system design, technical specifications, cost estimation, and analyzing vanadium electrolyte supply options. The company will also evaluate project financing and potential government funding opportunities.

Alcoa will provide support for the study, which will explore deployment options across its various sites and landholdings in the region. The ultimate goal is to determine how VFB technology can provide stable, long-duration energy storage for Alcoa's industrial operations.

Market Context

This partnership highlights the growing interest in long-duration energy storage solutions for heavy industry. Alumina refining is a highly energy-intensive process, and integrating large-scale batteries like VFBs could help manage electricity costs, improve grid stability, and support the integration of renewable energy sources. For investors, this study represents a significant potential use case for vanadium in the industrial energy sector, moving beyond grid-scale applications.
