South Africa’s Vanadium Advantage
According to reports from the Localisation Support Fund (LSF), South Africa possesses significant potential to develop a commercial vanadium redox flow battery (VRFB) value chain. The assessment comes after the LSF commissioned energy consultancy Customised Energy Solutions to evaluate the country’s competitive positioning in the emerging energy storage technology sector.

Sources indicate that South Africa holds vast vanadium resources with many deposits grading more than 1.5% vanadium pentoxide, which is considered high-grade by international standards. This mineral wealth, combined with growing global demand for long-duration energy storage solutions, reportedly creates a substantial opportunity for the country to advance its primary vanadium mining, refining and downstream processing capabilities.
Global VRFB Market Expansion
The analysis suggests the global installed VRFB capacity will increase tenfold from 4 GWh to 40 GWh by 2030, with notable installation acceleration predicted from 2027 onwards. CES industry research manager Avanthika Satheesh reportedly stated that the share of vanadium being used for VRFBs is currently 5%, but this is expected to increase to 27% by 2030, requiring the doubling of global vanadium production.
Analysts suggest that VRFBs are uniquely suitable for long-duration energy storage applications, with operational lifespans of between 25 and 30 years and no degradation even at 100% capacity. The technology is also described as inherently safe and thermally stable, using a non-flammable electrolyte that can operate across wide temperature ranges.
Economic Considerations and Cost Projections
The report states that high capital expenditure remains the most inhibiting factor to scaling VRFB production, currently standing at approximately $380 per kilowatt-hour. However, CES predicts this cost will decline to $230/kWh by 2030, reaching levelised cost of storage parity with lithium-ion batteries for applications exceeding eight hours of storage.
LSF CEO Irshaad Kathrada reportedly emphasized that countries building capacity early will define the next wave of clean energy manufacturing. “To unlock the vanadium opportunity, we must make the business and economic case work strongly. If we do not move decisively, we risk seeing this value migrate to other global players who are acting faster,” he stated during the presentation of findings.
Policy Framework and Global Context
According to the analysis, the global VRFB value chain is highly concentrated, with the top eight vanadium electrolyte manufacturers based in China accounting for 93% to 95% of global capacity. This concentration reportedly presents both opportunities and risks that call for regional diversification to mitigate supply chain vulnerabilities.
The LSF recommends establishing energy storage special economic zones dedicated to battery technology production, along with tax incentives, grants and preferential procurement for locally produced VRFB components. Sources indicate that countries including China, India, Australia and the United States have already provided government support for VRFB research and development or production-linked incentives.

Recyclability and Environmental Benefits
During a panel discussion hosted by LSF, consultancy Hatch senior process engineer Sudhir Thakurdin reportedly highlighted how the recyclability of VRFBs lowers the total cost of the technology compared with alternatives. The vanadium electrolyte itself is nearly 100% recoverable, which supports circular business models and provides benefits in respect of carbon emission reduction and other climate change goals.
Electricity and Energy Deputy Minister Samantha Graham-Maré reportedly stated that the South African Renewable Energy Masterplan sets out a clear roadmap for how localisation in the renewable energy and storage value chains can drive industrial growth and energy security. “Vanadium beneficiation and VRFB manufacturing align squarely with this vision, offering an opportunity to convert our mineral wealth into sustainable jobs, exports and technological capability,” she noted.
Regional Development Opportunities
The report highlights that some of South Africa’s vanadium reserves are located in Mpumalanga, which could help advance the just energy transition given this province’s coal-based economy that will need shifting. This positioning reportedly creates additional socioeconomic benefits beyond pure industrial development.
As global initiatives like the EU nations’ public procurement debates and technological advancements in adjacent sectors such as AI startups continue to evolve, the energy storage landscape is becoming increasingly competitive. With financial markets showing volatility as indicated by Federal Reserve rate cut discussions and major acquisitions like the Aligned Data Centers deal reshaping infrastructure investments, the timing for establishing VRFB manufacturing capacity appears critical.
The LSF concluded that a deliberate, coordinated push to support beneficiation, refining and manufacturing can anchor South Africa within global VRFB supply chains, while capturing meaningful value from the global energy transition and strengthening its industrial base. As companies across sectors demonstrate growth potential similar to LVMH’s recent performance and political developments like high-profile political donations influence market dynamics, the renewable energy storage sector represents a significant opportunity for emerging market economies.
