The global shift towards green energy is transforming industries worldwide, and South Africa is poised to play a significant role in this revolution. As the demand for sustainable technologies surges, the spotlight turns to "green metals"—the critical minerals driving this new era. In our latest article, we delve into South Africa's strategic position in the green metals landscape, exploring how the country can leverage its rich geological resources to meet the ambitious climate goals set by the Paris Agreement. Discover the challenges, opportunities, and transformative projects shaping South Africa's journey towards a sustainable and prosperous future.

The global landscape is undergoing a seismic shift from reliance on fossil fuels towards a greener future. Renewable energy technologies like wind turbines, solar panels, and electric vehicles are rapidly replacing traditional fossil fuel-based systems¹. Mining faces growing challenges due to environmental concerns, resource competition, and societal opposition, necessitating improvements in industry practices³.

At the heart of this clean energy revolution lies a group of minerals critical for the development and functionality of these innovative technologies - aptly named "green metals" or “minerals of the future”⁴. A shift towards zero-carbon technologies contrasts starkly with reliance on traditional hydrocarbon resources. Constructing solar photovoltaic (PV) plants, wind farms, and electric vehicles (EVs) typically demands a greater quantity of minerals compared to their fossil fuel-based equivalents⁵.

Furthermore, decarbonisation efforts in the mining industry are driven by the transfer to "green" metallurgy and the implementation of hydrogen technologies⁶. In addition, green primary iron production in South Africa using low-cost solar photovoltaic electricity could help global decarbonisation and boost exports, while promoting sustainable industry transformation⁷.

The World Bank estimates that, to meet the ambitious climate change goals set by the Paris Agreement, the production of green minerals will need to increase by nearly 500%⁸. This dramatic rise in demand presents a significant opportunity for resource-rich countries. South Africa, with its rich geological endowment, finds itself strategically positioned to capitalise on this growing demand

The Green Metals Landscape in South Africa

South Africa's mining sector has long been dominated by gold, platinum, and coal. However, the growing demand for green metals is creating new opportunities. The country boasts significant reserves of several key green metals:

• Platinum Group Metals (PGMs): South Africa is the world's leading producer of PGMs, which include platinum, palladium, and rhodium. These metals play a crucial role in hydrogen fuel cell technology, considered a promising alternative to traditional internal combustion engines.
• Manganese: Another critical component of electric vehicle (EV) batteries is manganese. South Africa holds substantial manganese reserves, positioning the country to play a significant role in the burgeoning EV market.
• Vanadium: South Africa has considerable reserves of vanadium, used in redox flow batteries and steel alloys.

While not as abundant as some other countries in certain green metals, South Africa still holds notable nickel reserves, integral to lithium-ion batteries, and lithium, the heart of these batteries. Recent discoveries indicate promising potential for lithium resources. Additionally, South Africa has potential reserves of Rare Earth Elements (REEs), critical for various high-tech and green applications.

The Green Metals Transition: A Just Path Forward

South Africa's Integrated Resources Plan⁹ emphasises a "just transition" from fossil fuels towards renewables. The South African Presidential Climate Commission's Just Transition Framework outlines principles and policies for this shift, with the mining sector poised to play a crucial role in supplying the necessary minerals¹⁰.

Africa's participation in the global value chains for green and transition minerals is currently concentrated at the initial stages through exploration, extraction, and some processing. For example, South Africa produces nickel, and vanadium electrolyte for flow batteries. Locally assembled lithium-ion batteries are used in various applications, such as remote power systems and off-grid renewable energy projects. Additionally, the African electric motorcycle industry is rapidly growing, with companies across the continent innovating and retrofitting conventional motorcycles with electric motors

Recent Developments in South Africa

• The Northern Cape region is emerging as a key player with advancements in copper-zinc ventures and the discovery of copper-nickel deposits. Production hubs like the Prieska Copper-Zinc Mine and Okiep Copper Project are expected to yield "green" metals.
• A green hydrogen hub project in Saldanha Bay will utilise carbon capture technology and renewable energy-produced hydrogen for steel production.
• A $1 billion investment partnership between QGlobal Commodities (QGC) and Abu Dhabi's F9 Capital Management aims to develop vital green metal deposits like lithium, copper, and nickel across southern and eastern Africa.
• Various new entrants are emerging in battery manufacture and assemblage.

Beyond Extraction: Beneficiation for Maximum Value

Simply extracting green metals isn't enough. Beneficiation, the process of upgrading the raw materials, is crucial for capturing a larger share of the value chain^{11 12}.

Investing in beneficiation facilities would allow South Africa to produce battery-grade lithium, high-purity manganese, and other value-added products. This not only increases export revenue but also positions thecountry as a potential hub for green technology manufacturing in Africa¹³. Operating across the entire value chain, coupled with a commitment to Environmental, Social, and Governance (ESG) principles, offerssubstantial economic benefits, particularly concerning skill development and job creation in mining communities¹⁴.

Challenges and Opportunities

The extraction and processing of green metals pose unique challenges including environmental impacts and the need for advanced technologies. However, these challenges present opportunities for innovation and collaboration.

• Sustainable Mining Practices: Implementing environmentally friendly mining techniques such as minimising land disturbance, reducing water usage, and effective waste management is crucial. Additionally, advancements in mining technology like automation, AI, and the Internet of Things (IoT) can enhance efficiency and reduce environmental impact.
• Electricity supply: Load shedding and electricity supply issues hinder smelters and refiners. Surging electricity tariffs and regulatory hurdles around self-generation projects further complicate matters.
• Regulatory Compliance: Navigating South Africa's regulatory landscape requires expertise in local laws and international standards.
• Infrastructure Development: Efficient transportation and processing infrastructure are vital for the green metals supply chain. Logistics infrastructure, designed for high-value precious metals, needs adaptation to transport bulky and heavy future minerals.
• Strategic Partnerships and Investment: Collaboration between mining companies, government entities, and engineering consulting firms is essential to unlock the full potential of South Africa's green metals. Strategic partnerships can attract investment, drive technological innovation, and promote sustainable practices.
