South Africa’s hydrogen strategy increasingly extends beyond exporting green hydrogen toward developing domestic technology and manufacturing capabilities. The commissioning of a 2 kilowatt proton exchange membrane (PEM) electrolyzer at Sasol’s Research and Technology campus in Sasolburg represents a research focused step in that direction, providing a platform to evaluate locally developed hydrogen production technology under real operating conditions while supporting skills development and industrial collaboration.
The electrolyzer was developed through the Hydrogen South Africa (HySA) Program, an initiative of the Department of Science, Technology and Innovation (DSTI), and was commissioned through a partnership involving Sasol, the South African National Energy Development Institute (SANEDI), and North-West University (NWU).
Although the system is small compared with commercial electrolyzers measured in megawatts, its significance lies in technology validation rather than hydrogen output. The research platform will be used to study electrolyzer performance, system integration, and operational behavior under variable renewable electricity supply, addressing one of the principal technical challenges associated with large scale green hydrogen production.
Unlike hydrogen systems powered by constant electricity sources, renewable powered electrolyzers must operate efficiently despite fluctuations in wind and solar generation. Understanding how locally developed equipment responds to intermittent power is considered essential for improving system reliability and advancing technology readiness before commercial deployment.
The project also reflects South Africa’s broader industrial strategy of leveraging its abundant platinum group metals (PGMs) to participate more extensively in the global hydrogen economy. PEM electrolyzers rely on platinum group metal catalysts, creating potential opportunities for higher value domestic manufacturing rather than exporting raw minerals alone.
Speaking at the commissioning ceremony, Science, Technology and Innovation Minister Professor Blade Nzimande emphasized the connection between critical mineral beneficiation and hydrogen technology development. He said expanding domestic capabilities across upstream, midstream, and downstream hydrogen industries could strengthen South Africa’s industrial competitiveness while supporting future exports and domestic green hydrogen applications.
This emphasis on value addition reflects a recurring theme in South Africa’s hydrogen policy. The country possesses some of the world’s largest platinum reserves, yet much of the economic value associated with hydrogen technologies currently resides in overseas manufacturing of fuel cells, electrolyzers, and related equipment. Developing domestic engineering capabilities could allow South Africa to capture a larger share of the hydrogen value chain.
For Sasol, the project aligns with the company’s longer term transition strategy. Historically one of the world’s largest producers of synthetic fuels and chemicals, Sasol has identified hydrogen as a potential feedstock for lower carbon fuels and chemical production. Testing locally developed electrolyzer technology at its research facilities provides an opportunity to evaluate future production pathways while supporting domestic technology development.
The collaboration also highlights the role of public research institutions in advancing hydrogen innovation. According to Professor Dmitri Bessarabov, Director of the HySA Infrastructure Centre of Competence at North-West University, the program focuses on translating laboratory research into industrial applications through demonstration, testing, validation, and gradual progression toward higher technology readiness levels.
Technology readiness remains an important issue for emerging hydrogen industries globally. While commercial electrolyzers are already available from international manufacturers, countries seeking to establish domestic hydrogen sectors increasingly view local research, manufacturing expertise, and engineering capabilities as strategic assets that can reduce dependence on imported technologies.
SANEDI expects operational data generated by the electrolyzer to support future hydrogen development using South Africa’s natural advantages, including platinum resources, strong solar and wind potential, available land, and access to seawater that can be desalinated for hydrogen production.
Despite these advantages, South Africa continues to face significant challenges before establishing a competitive green hydrogen industry. Large scale deployment will require substantial investment in renewable electricity generation, water infrastructure, transport networks, and export facilities, alongside continued reductions in electrolyzer costs and improvements in technology performance.
The Sasol demonstration does not address these commercial scale challenges directly. Instead, it provides an experimental platform designed to strengthen technical expertise and evaluate locally developed equipment before larger projects move toward deployment.
