Hydrogen Mobility and Platinum Group Metals Reshaping North West Province

The Geology Beneath the Green Economy: How South Africa’s PGM Reserves Are Reshaping Hydrogen Mobility

Long before hydrogen became a geopolitical talking point or a decarbonisation headline, the Bushveld Igneous Complex was quietly accumulating the metals that would make the entire hydrogen economy possible. Formed through one of the largest known magmatic intrusion events in Earth’s history, this geological formation underpins South Africa’s claim to more than 80% of the world’s platinum group metal reserves — a concentration so dominant it borders on monopolistic. What was once primarily a platinum jewellery and autocatalyst story is now evolving into something far more structurally significant: the material foundation of a zero-emissions energy system.

The convergence of hydrogen mobility and platinum group metals in North West Province represents one of the most compelling resource-to-technology narratives currently unfolding in global energy markets. Recent infrastructure developments at North West University’s Potchefstroom Campus have moved this narrative from theoretical alignment to tangible deployment, with implications that extend well beyond South Africa’s borders.

Why PGMs Are Structurally Irreplaceable in the Hydrogen Value Chain

Understanding why platinum group metals occupy such a critical position in the hydrogen economy requires looking at the electrochemistry involved. In a proton exchange membrane (PEM) electrolyser, water is split into hydrogen and oxygen through an electrically driven process. The electrode surfaces where this reaction occurs must withstand extreme oxidative conditions, high current densities, and highly acidic environments. Only iridium, used as the anode catalyst coating, and platinum, used on the cathode side, can consistently meet these performance and durability requirements at commercially relevant scales.

This point is illustrated clearly by a widely circulated image in the hydrogen industry: a PEM electrolyser electrode pair showing an iridium-coated anode enabling the oxygen evolution reaction alongside a platinum-coated cathode. The visual encapsulates a critical technical reality — no commercially scalable substitute currently exists for these PGM-based catalysts in acidic PEM environments. Furthermore, PEM technology expansion is accelerating globally, which only deepens this structural dependency.

The same metals then perform a second function downstream. In fuel cell electric vehicles, platinum acts as the catalyst that facilitates the controlled recombination of hydrogen and oxygen to produce electricity and water vapour. This dual-role dependency means PGMs are embedded in both the production and the consumption ends of the hydrogen value chain simultaneously.

The critical insight here is not simply that PGMs are useful — it is that demand for these metals will compound from two separate directions as hydrogen scales. Production infrastructure (electrolysers) and consumption infrastructure (fuel cells) each require PGM inputs, creating a multiplier effect that most commodity demand models have historically underweighted.

Projected platinum demand from hydrogen applications is expected to exceed 600,000 ounces annually by 2030, with longer-term forecasts pointing toward 850,000 to 900,000 ounces per year as fuel cell deployment reaches commercial scale across transport and stationary applications. These figures represent a demand stream that did not meaningfully exist a decade ago.

What Just Happened at NWU Potchefstroom, and Why It Matters

Two distinct but complementary infrastructure milestones have been formalised at North West University’s Potchefstroom Campus, each representing a different layer of South Africa’s hydrogen development ambition.

The first is the formal handover of a mobile hydrogen refuelling and generation system to Toyota South Africa Motors. This facility generates hydrogen on-site through PEM electrolysis — the same PGM-catalysed process described above — and serves as a strategic demonstration platform for hydrogen fuel cell electric vehicle technologies. Critically, it showcases locally developed intellectual property rather than imported systems, reinforcing the domestic capability narrative central to South Africa’s beneficiation agenda.

The second development is the opening of a rapid prototype facility at the same Potchefstroom Campus. This centre, established through a three-way partnership between the Department of Science, Technology and Innovation, North West University, and PGM producer African Rainbow Minerals (ARM), serves multiple functions simultaneously:

• Accelerating the incubation of water electrolysis technologies from concept through to pilot scale
• Advancing component-level innovation in green hydrogen production systems
• Enabling integration testing across laboratory, pilot, and industrial-scale configurations
• Building a locally trained engineering and technical workforce with hydrogen-specific expertise

Facility	Primary Partner	Function	Technology Basis
Mobile hydrogen refuelling station	Toyota South Africa Motors	FCEV demonstration and local IP showcase	PEM electrolysis
Rapid prototyping and testing centre	African Rainbow Minerals + DSTI	R&D, training, and scale-up acceleration	Water electrolysis systems

Professor Dmitri Bessarabov, who directs the HySA Infrastructure Competence Centre, has framed the launch of the rapid prototyping facility as marking genuine momentum toward the commercialisation of hydrogen technologies within South Africa. His characterisation reflects a broader recognition that demonstration infrastructure reduces investor and policy uncertainty in ways that research publications alone cannot achieve.

An important nuance highlighted by Bessarabov is the paradox at the heart of South Africa’s hydrogen opportunity: the country hosts more than 80% of global PGM reserves, yet its domestic deployment of the very technologies those metals enable remains comparatively limited. Closing this gap is both the central challenge and the most significant commercial opportunity the HySA ecosystem is designed to address.

HySA: The Programme Architecture Connecting Mining to Mobility

The Hydrogen South Africa (HySA) programme was established by the Department of Science, Technology and Innovation as a national flagship initiative with an explicit mandate to develop hydrogen and fuel cell technologies across the full value chain of South Africa’s mineral endowment, with PGMs positioned as the central enabling material throughout.

HySA’s structure is intentionally comprehensive, spanning four interconnected strategic objectives:

1. Resource beneficiation — transforming raw PGM output into high-value catalyst components suitable for electrolyser and fuel cell manufacturing, capturing more economic value domestically before export
2. Technology development — building South African-designed electrolysis systems and fuel cell architectures rather than relying exclusively on imported platforms
3. Infrastructure deployment — constructing refuelling networks, hydrogen valleys, and demonstration facilities, of which the NWU Potchefstroom developments are the latest examples
4. Workforce development — training engineers, technicians, and researchers capable of operating, maintaining, and innovating across hydrogen systems

What makes the HySA model structurally significant from an investor perspective is the recognition embedded within it that commodity-level participation is insufficient for value creation in the energy transition. A country that supplies PGMs to overseas catalyst manufacturers, who then supply components to hydrogen technology companies, captures only the lowest-margin portion of a high-margin value chain. HySA is designed, at least conceptually, to move South Africa further up that chain.

The barriers to achieving this transition remain substantial. PGM supply constraints continue to complicate downstream investment decisions alongside price volatility. Domestic demand signals for fuel cell electric vehicles are still nascent. Regulatory frameworks governing hydrogen as an energy carrier are still being developed. And the manufacturing infrastructure for membrane electrode assemblies and catalyst components — the critical middle steps between raw PGM and deployable technology — is currently concentrated offshore.

African Rainbow Minerals and the Mine-to-Market Imperative

ARM’s participation as a founding partner of the NWU rapid prototyping facility signals something more strategically significant than corporate social investment. As a substantial PGM producer operating within the Bushveld Igneous Complex, ARM occupies the upstream end of a value chain that the global energy transition is fundamentally restructuring.

ARM CEO Phillip Tobias was present at the facility’s opening, a detail that reflects executive-level commitment rather than peripheral participation. The company’s involvement illustrates three strategic priorities that are increasingly defining how PGM miners position themselves relative to the hydrogen economy:

• Vertical integration potential — establishing a presence in technology development creates an option to participate in catalyst manufacturing and system supply as those markets mature
• Domestic beneficiation alignment — partnering with research institutions supports government objectives to add value to PGMs within South Africa before export, potentially improving regulatory relationships and social licence
• Long-term demand creation — accelerating the commercialisation of hydrogen technologies that consume PGMs represents a direct mechanism for expanding the market for ARM’s primary product

This represents a subtle but important shift in how resource companies are approaching the energy transition: not as passive observers of demand shifts, but as active participants in building the downstream infrastructure that will ultimately determine the scale and trajectory of PGM consumption.

Hydrogen Valleys and the North West Geographic Advantage

The concept of a hydrogen valley has become the preferred organisational model for hydrogen ecosystem development globally. Rather than dispersed, point-source hydrogen projects, the hydrogen valley framework clusters production, storage, distribution, and consumption within an integrated geographic zone — typically within a radius of approximately 50 kilometres. This co-location strategy minimises infrastructure redundancy, reduces logistics costs, and accelerates the commercial learning curve.

EU energy geopoliticist Attila Menyhart has noted that the strategic framing around hydrogen valleys has shifted decisively toward these integrated clusters where production, storage, and heavy industrial consumption occur within the same geographic footprint, specifically because this approach minimises infrastructure risk during the commercialisation phase.

North West Province presents a compelling geographic case for hydrogen valley development. The region sits within South Africa’s broader mineral corridor, connecting major industrial zones across Limpopo, Gauteng, and KwaZulu-Natal. PGM mining operations already present in the Bushveld Complex could supply catalyst feedstock. Research and demonstration infrastructure is now established at NWU. And existing mining equipment and transport fleets represent a captive initial consumption base for locally produced green hydrogen.

Hydrogen is increasingly being framed not just as a fuel but as what some analysts describe as a geopolitical freedom tool — a means for resource-rich nations to develop export independence from fossil fuel supply chains while simultaneously monetising their mineral endowments through technology rather than raw commodity sales alone. Indeed, the role of critical minerals in the energy transition is now firmly at the centre of national energy security strategies worldwide.

Global Hydrogen Mobility Momentum and the PGM Demand Signal

The infrastructure developments at Potchefstroom are not occurring in isolation. A wave of international automotive and industrial hydrogen commitments is progressively strengthening the demand thesis for PGMs across multiple geographies simultaneously.

Key global hydrogen mobility developments documented as of May 2026:

• Toyota and Isuzu have formalised a collaborative development agreement targeting mass production of a next-generation light-duty fuel cell electric truck. The vehicle integrates Isuzu’s battery-electric truck platform with Toyota’s hydrogen fuel cell system, with first production targeted for 2027
• Hyundai Motor Group signed a multi-year partnership with the Georgia Institute of Technology focused on hydrogen mobility solutions, deploying Nexo fuel cell vehicles alongside hydrogen infrastructure for research and zero-emissions logistics operations
• Lhyfe signed a multi-year green hydrogen supply contract with BMW Group to supply BMW’s Steyr facility in Austria — the site responsible for the series development and industrialisation of BMW’s hydrogen fuel cell system — with Lhyfe deploying its own hydrogen transport fleet for delivery
• The European Hydrogen Backbone initiative is advancing plans to convert existing natural gas pipeline networks into hydrogen transport corridors across Europe, repurposing existing infrastructure rather than building from scratch, significantly reducing capital requirements
• In Uganda, Italian electrolyser manufacturer ErreDue secured a €900,000 green hydrogen contract to supply equipment for a steel plant, marking an early-stage application of green hydrogen in East African industrial hard-to-abate sectors

Partnership	Region	Technology Focus	Timeline
Toyota + Isuzu	Japan	FC light-duty truck	Production by 2027
Hyundai + Georgia Tech	United States	FCEV mobility and research	Multi-year programme
Lhyfe + BMW Group	Austria	Green H₂ supply for FC development	Multi-year contract
European Hydrogen Backbone	Europe	Pipeline repurposing for H₂ transport	In progress
ErreDue + Uganda steel plant	East Africa	Industrial green H₂ supply	Contract secured

Each of these commitments represents incremental platinum catalyst demand at the production level (electrolysers) and at the consumption level (fuel cells). Aggregated across dozens of similar partnerships forming globally, the cumulative PGM demand trajectory points consistently upward through the late 2020s. Consequently, the intersection of hydrogen mobility and platinum group metals in North West is becoming an increasingly important lens through which to understand South Africa’s strategic positioning.

South Africa’s Diplomatic Push and the Green Hydrogen Export Opportunity

Beyond domestic deployment, South Africa has been actively constructing an international positioning strategy around green hydrogen. In April 2026, South Africa’s Industrial Development Corporation JET-IP programme director for green hydrogen, Rebecca Maserumule, presented the country’s first-mover green hydrogen project development approach at the United Nations Industrial Development Organisation conference in Vienna, attended by representatives from 70 countries.

In February 2026, South African President Cyril Ramaphosa framed green hydrogen as central to Africa’s energy opportunity during discussions at Abu Dhabi Sustainability Week with UAE President Sheikh Mohamed bin Zayed Al Nahyan. The conversation emphasised the structural advantages Africa holds for green hydrogen production: exceptional solar irradiation, strong wind energy corridors, significant hydroelectric potential, and a world-leading critical minerals endowment with PGMs at the centre.

These diplomatic engagements reflect a recognition that South Africa’s green hydrogen opportunity extends beyond domestic decarbonisation. Furthermore, the role of renewable energy in mining operations is increasingly intertwined with this export ambition, as lower-cost green energy inputs directly reduce the cost of hydrogen production. The country’s PGM reserves create a unique dual advantage: the raw materials needed to build the production and conversion technology, and the renewable resource base needed to produce the green hydrogen itself.

The Challenges That Remain Before the Vision Becomes Reality

Despite the genuine progress represented by the NWU Potchefstroom developments and the global momentum building around hydrogen mobility, significant structural barriers remain between South Africa’s current position and a fully realised hydrogen economy.

PGM price dynamics present a paradox. Platinum has experienced meaningful price pressure in recent periods, creating uncertainty for downstream investors who need sustained feedstock pricing signals to commit capital to catalyst manufacturing facilities. As of early May 2026, platinum was trading at approximately $1,943 per ounce — a level that reflects continued market uncertainty around the timing of large-scale hydrogen demand materialisation.

Technology localisation gaps remain significant. While South Africa produces the raw PGM inputs, the majority of membrane electrode assembly manufacturing, catalyst preparation, and fuel cell system integration occurs in Europe, Japan, and South Korea. Closing this gap requires not just capital investment but the development of specialised manufacturing capabilities that take years to establish.

Infrastructure scaling requires capital at a different order of magnitude. Mobile refuelling stations and prototype testing facilities are valuable proof-of-concept investments, but they are not the same as a national hydrogen refuelling network. The pathway from demonstration to commercial deployment requires sustained public and private capital commitment over extended timeframes.

Recycling infrastructure is an underappreciated future requirement. As first-generation PEM fuel cells and electrolysers reach end-of-life, the PGMs embedded within them will represent a significant secondary supply stream. Developing domestic recycling capability to recover and reprocess these catalysts is critical to long-term supply resilience and cost competitiveness — and remains largely underdeveloped within South Africa currently. In addition, mining’s clean energy transition will increasingly depend on resolving precisely these kinds of circular economy challenges at scale.

Frequently Asked Questions: Hydrogen Mobility and PGMs in North West

What is PEM electrolysis and why does it specifically require platinum group metals?

Proton exchange membrane electrolysis uses an electrically charged polymer membrane operating in a highly acidic environment to split water into hydrogen and oxygen. Iridium is applied to the anode where oxygen is produced, and platinum is applied to the cathode where hydrogen forms. These metals are used because they maintain catalytic activity and physical stability under the extreme oxidative and acidic conditions inside a PEM electrolyser. Alternative non-precious metal catalysts lack the durability required for commercial lifespans at industrial operating conditions.

How far can a hydrogen fuel cell electric vehicle travel on a single refuelling?

Current hydrogen FCEV technology delivers a practical driving range of approximately 500 to 600 kilometres per refuelling cycle. This is broadly comparable to conventional internal combustion vehicles and exceeds the range of most battery electric vehicles in heavy-duty and long-distance transport applications, which is why hydrogen fuel cell technology is attracting particular interest for trucks and commercial fleets.

What is the HySA Infrastructure Centre of Competence?

HySA Infrastructure is one of three national centres of competence operating under the Hydrogen South Africa programme, which was established by the Department of Science, Technology and Innovation. The Infrastructure centre, directed by Professor Dmitri Bessarabov at North West University, focuses specifically on hydrogen production, storage, and delivery systems — including electrolyser development and the refuelling infrastructure recently demonstrated at Potchefstroom. For broader context on South Africa’s hydrogen future, recent coverage highlights how hydrogen mobility and platinum group metals in North West are gaining sustained strategic attention.

What does African Rainbow Minerals’ involvement in the NWU facility actually mean for its business model?

ARM’s participation represents an early-stage move toward vertical integration within the hydrogen value chain. By investing in research infrastructure that develops and demonstrates PGM-catalysed electrolysis technologies, ARM is positioning itself closer to the downstream markets that will ultimately consume the metals it mines. Whether this translates into catalyst manufacturing partnerships or technology licensing revenue depends on the commercial maturity of South Africa’s hydrogen sector over the next decade.

Could North West Province realistically become a hydrogen valley?

The geographic and industrial prerequisites are credible. The region has PGM mining operations capable of supplying catalyst feedstock, research infrastructure now established at NWU, and existing heavy transport and mining equipment fleets that could serve as initial green hydrogen consumers. The primary constraints are capital availability, regulatory clarity on hydrogen as an energy carrier, and the timeline required to build production and distribution infrastructure at meaningful scale. Analysts examining PGMs and economic development in South Africa consistently identify North West as a region where the convergence of mining heritage and hydrogen ambition is most pronounced.
