Researchers from the JENano Group at the University of Johannesburg (UJ) are advancing South Africa’s green hydrogen ambitions through integrated research spanning computational materials design, advanced electrode fabrication, membrane-free electrolysers, hydrogen storage and fuel-cell systems. Working with local and international partners, the group is developing technologies aimed at supporting the country’s transition to a low-carbon economy while addressing practical deployment challenges.
Green hydrogen is produced by splitting water using electricity generated from renewable sources such as solar and wind power. Unlike conventional hydrogen produced from fossil fuels, green hydrogen generates no carbon emissions at the point of production. It is increasingly viewed as a critical solution for decarbonising hard-to-abate sectors such as steelmaking, chemicals, heavy transport and long-duration energy storage.
With abundant solar and wind resources, South Africa is well positioned to become a producer and exporter of green hydrogen. However, achieving this potential will require technologies that can operate efficiently, reliably and at competitive cost.
The JENano Group forms part of UJ’s Department of Mechanical Engineering Science and is led by Prof Tien-Chien Jen, holder of the South African Research Chairs Initiative Chair in Green Hydrogen, funded through Sasol and the National Research Foundation.
