Dr Sabelo Jeza has graduated with a PhD in Chemical Engineering after an academic journey which took root at KwaHluzingqondo High School in Umkomaas, where his strengths in mathematics and physical sciences soon became evident.
Jeza went on to complete his undergraduate studies at UKZN before pursuing his master’s degree at Stellenbosch University. Drawn back to UKZN for his doctorate, he credits the University’s supportive and harmonious environment for fostering both academic excellence and personal growth. His path to Chemical Engineering was influenced by an interest in solving complex problems. “Chemical engineering provides the perfect platform to apply this mindset to real-world challenges,” he said.
Jeza’s PhD research focused on developing practical ways to produce cleaner fuels, specifically green hydrogen. His work explored efficient and sustainable methods for producing an alternative fuel to conventional petrol and diesel. “I studied how to make this fuel efficiently and sustainably so that it can help reduce pollution and contribute to a cleaner energy future,” he said.
Sasol, South Africa’s leading energy company, played a pivotal role in Jeza’s journey. “Sasol was the key factor behind my decision to pursue a PhD,” he noted. “Their innovative technologies, such as Fischer-Tropsch processes, have always impressed me. I have long aspired to be part of their team, especially as they transition toward cleaner energy.” With Sasol’s bursary support he was able to take up the opportunity to work on his doctoral research while contributing to the energy sector’s green transition.
He firmly believes his PhD has societal impact: “As the country works toward reducing its carbon footprint and transitioning to green hydrogen, the expertise I have developed positions me to contribute directly to these efforts. I hope to be at the forefront of helping South Africa achieve its Net Zero goals.”
Jeza is currently part of the Sasol Process Engineering team at the National Petroleum Refiners of South Africa (Natref) oil refinery. Looking ahead, he aspires to contribute to Sasol’s and South Africa’s transition to cleaner fuels in an economically viable way, while ensuring a stable and reliable energy supply. He also plans to collaborate with universities to accelerate research and innovation in sustainable energy solutions, with the long-term goal of retiring as an influential professor who contributes to both the country’s academic and industrial development!
Jeza has been supported and inspired by many, but he especially acknowledged his high school teachers, Mr Mcebo Innocent Ntshangase (Physical Science) and Ms Snenhlanhla Ntshembeni (Mathematics). “Their guidance and encouragement played a key role in developing my interest and strengths in the sciences, which ultimately laid the foundation for my pursuit of Chemical Engineering,” he said.
Despite his busy schedule, Jeza makes time for activities that keep him grounded. “I make sure to stay active by jogging and spending time with family and friends,” he shared.
He also enjoys continuing research within his field to stay abreast of new developments in sustainable energy and chemical engineering.
Jeza said he lived by the statement: “I don’t do things because they are easy, but because they are difficult.”
With his PhD now complete, he is well on his way to becoming one of the key players shaping South Africa’s transition to a cleaner, greener energy future.
