CAPE TOWN—As the global race for energy transition materials intensifies, the historical bond between the automotive sector and platinum-group metal (PGM) miners is evolving from simple buyer-seller transactions into complex, strategic alliances.
Delegates at the Investing in African Mining Indaba 2026 in Cape Town heard this week that these partnerships spanning financial, equity, and recycling frameworks are becoming the linchpin for de-risking the shift toward hydrogen and electric mobility.
While the relationship dates back to the 1960s with the advent of the catalytic converter, the current landscape is increasingly defined by the scarcity of “new-energy” metals, such as iridium, and the rigorous demands of environmental, social, and governance (ESG) compliance.
The necessity of securing these materials has never been more acute, particularly with the rapid expansion of the Chinese automotive sector and its massive export volumes. Experts highlighted that as Chinese manufacturers increase their global footprint, the demand for PGMs to treat internal combustion emissions remains high, even as the world eyes a future hydrogen economy.
This “dual-track” demand is placing immense pressure on existing supply chains, where specialised metals like iridium essential for proton-exchange membrane (PEM) electrolysers are already heavily committed to existing customers through long-term offtake agreements.
“The evolution of the PGM sector has been in lockstep with the automotive sector,” noted J.J. Messner de Latour, purchasing sector lead at the Initiative for Responsible Mining Assurance (IRMA), in a media statement following the session. ”
In many respects, sustainability and ESG have been an indelible part of the journey for PGMs. Resilient supply chains are built on transparency and good governance. A business with a social license to operate will have continuity of supply.”
Market analysts pointed out that the structural scarcity of certain PGMs is a looming bottleneck for the green hydrogen rollout. With total annual iridium production hovering around 259,000 ounces 80% of which is already locked in via offtake contracts new market entrants face a steep climb to secure the necessary inventory.
This has prompted a recommendation for industry players to move away from traditional “command” relationships and instead foster a diversity of supply, ensuring that industrial clients are not overly dependent on a single mining source in a volatile geopolitical climate.
South Africa, as the world’s leading PGM producer, remains the focal point for global tech firms looking to scale their green energy infrastructure. Representatives from major European energy groups confirmed at the Indaba that South Africa is viewed as a primary partner for sustainable manufacturing, particularly for gigawatt-scale electrolyser factories.
By aligning long-term mine planning with fast-moving technological lifecycles, both sectors aim to future-proof operations and ensure that the minerals fueling the green revolution are sourced through markets that are themselves commercially and ethically sustainable.
