Hydrogen, the simplest and most abundant element in the universe, powers the stars through nuclear fusion, converting into helium and releasing immense energy. Now, researchers at North-West University (NWU) in South Africa are harnessing this star-like potential to position the country as a leader in clean energy. Through the Hydrogen South Africa (HySA) Infrastructure Centre of Competence, co-hosted by NWU and the Council for Scientific and Industrial Research (CSIR), scientists are developing technologies that could transform South Africa's energy landscape, reducing reliance on coal and enabling exports of green hydrogen-derived products like ammonia.

This work aligns with South Africa's national hydrogen strategy, emphasizing the university's pivotal role in higher education and innovation. NWU's efforts not only advance research but also create skills development opportunities, preparing students for careers in the burgeoning green hydrogen sector. For those exploring opportunities in energy research, platforms like higher ed jobs showcase faculty and research positions at institutions driving such breakthroughs.

🌟 NWU's HySA Infrastructure: The Heart of Hydrogen Innovation

The HySA Infrastructure Centre, directed by Prof Dmitri Bessarabov at NWU, focuses on hydrogen production via advanced water electrolysis, storage solutions, delivery systems, and fuel cell technologies. Established under the Department of Science and Innovation's (DSI) flagship programme, it leverages South Africa's abundant platinum group metals (PGMs)—holding 70-80% of global reserves—for catalysts in proton exchange membrane (PEM) electrolysers and fuel cells. PEM electrolysers split water into hydrogen and oxygen using electricity from renewables like solar and wind, producing 'green hydrogen' with zero emissions.

At NWU's Potchefstroom campus, the advanced electrolysis laboratory tests next-generation systems, while the hydrogen piloting area demonstrates full-scale production, storage, and refuelling. These facilities supply on-demand hydrogen for applications from stationary power to vehicles, bridging lab research to real-world deployment. Prof Bessarabov notes, 'Hydrogen is both an energy carrier and a critical industrial chemical commodity essential for ammonia, fertilizers, and petrochemicals.' This research positions NWU graduates for roles in sustainable engineering, with near-100% employment rates from hydrogen programmes.

From Prototypes to Practical Applications: Key Achievements

HySA at NWU has delivered tangible prototypes, including catalyst-coated membranes (CCMs), electrolyser stacks, and a hydrogen refuelling station in partnership with Toyota South Africa Motors. During the COVID-19 pandemic, seven hydrogen fuel cell units powered 1 Military Hospital in Pretoria, showcasing reliability in critical infrastructure—a collaboration with DSI, Department of Defence, and Department of Public Works and Infrastructure.

• Developed large-scale demonstrators for water electrolysers and compression systems.
• Advanced passive autocatalytic recombiners (PARs) for safety in hydrogen environments.
• Supported deployment of fuel cells for backup power, outperforming batteries for long-term storage.

Recent expansions include new electrolysis testing stations, enhancing R&D capacity amid South Africa's push for a hydrogen economy. These milestones highlight NWU's transition from theory to technology transfer, fostering spin-offs and industry partnerships essential for higher education's economic impact. Aspiring researchers can find postdoctoral and lecturer positions via research jobs in this field.

South Africa's Unique Advantages in the Global Hydrogen Race

South Africa boasts world-class solar irradiation in the Northern Cape, wind corridors along the coast, and vast PGM reserves crucial for hydrogen tech: platinum for fuel cells, iridium for electrolysers, ruthenium for ammonia synthesis. Linking renewables to electrolysis enables 'sunshine exports' as green ammonia to Europe and Asia, where renewables are scarce. Prof Bessarabov emphasizes, 'Countries like South Africa can export their abundant renewable resources in the form of hydrogen-derived products.'

The nation's Hydrogen Commercialisation Strategy Roadmap (HCST) targets 4-6 gigawatts of renewable-powered electrolysers by 2035, creating jobs and beneficiating minerals locally. NWU's role extends to continent-wide opportunities, building Africa's hydrogen ecosystem for energy access and industrialisation.

Overcoming Challenges: Infrastructure and Geographic Hurdles

A primary challenge is the mismatch between production sites (renewable-rich Northern Cape) and demand centres (industrial Gauteng). Solutions include hydrogen pipelines, high-pressure trucking, liquefaction at -253°C, and carriers like ammonia or liquid organic hydrogen carriers (LOHCs). HySA researches cost-effective storage and transport to make green hydrogen competitive.

NWU addresses safety with PAR technology, preventing explosive mixtures in enclosed spaces. Scaling manufacturing domestically for electrolysers and stacks is key to job creation—potentially thousands in PGM beneficiation alone. For students, this translates to hands-on projects in chemical engineering and materials science, preparing them for faculty jobs or industry R&D.

Skills Development: NWU's Green Hydrogen Centre of Specialisation

The Mining Qualifications Authority designated HySA at NWU as host for the Green Hydrogen Centre of Specialisation, aligning curricula with industry needs. Programmes train artisans, technicians, and engineers in electrolysis, fuel cells, and safety protocols. With Africa's young workforce and mineral wealth, NWU's initiatives could employ graduates at 100% rates, as seen in existing HySA-linked studies.

• Courses cover PEM technology, from membrane electrode assemblies to system integration.
• Partnerships with Toyota and SANEDI provide internships and placements.
• Focus on women and rural youth for inclusive growth.

Broader Impacts: Economic Transformation and Energy Security

Hydrogen supports food security via green ammonia for fertilizers, decarbonises heavy industry, and stores excess renewables seasonally. For South Africa, it reduces coal dependency (90% of electricity), cuts emissions, and boosts GDP through exports. NWU's research enables PGM value addition, creating high-skill jobs over raw mineral exports.

Stakeholder views: Industry leaders praise HySA's prototypes; government sees it as pivotal for the Hydrogen Society Roadmap. Challenges like high upfront costs are offset by falling electrolyser prices (down 60% since 2015 globally).Learn more on HySA's site.

Future Outlook: Scaling Up and Global Partnerships

Plans include commercial-scale electrolysers by 2028, Africa's first hydrogen mini-valley, and international collaborations like with DUT and SANEDI. NWU eyes quantum leaps in efficiency, targeting levelised costs below $2/kg H2. Continentally, Namibia and Botswana partner on pipelines.

For higher ed, this means more PhDs, postdocs, and spin-out companies. Prof Bessarabov envisions, 'Building an African hydrogen ecosystem for industrialisation and skills.'
