The University of the Free State (UFS) has appointed Prof Prince Ngobeni as Principal of the Qwaqwa Campus as from 1 February 2024.

Prof Ngobeni completed his first qualification in Analytical Chemistry at the then Technikon North-West before furthering his studies at the then Technikon Pretoria. He completed a DTech in Chemistry at the Tshwane University of Technology (TUT) in 2003. In 2016, he enrolled for a Doctor of Business Administration in Higher Education at the University of Bath in England. 

His lecturing career began at TUT in 1995 where he progressed from Head of Department: Chemistry in 2003 to Associate Dean: Faculty of Science in 2010, before being appointed as Executive Dean of the Faculty of Sciences at TUT in 2015 – a position he held until 2023. He also served as Interim Campus Rector of TUT’s Pretoria Campus from 2018 to 2020.

“With extensive years of academic leadership experience, Prof Ngobeni has the experience required to guide the Qwaqwa Campus towards the university’s Vision 130. The campus is already recognised as a leader in some of its unique research fields, and Prof Ngobeni’s strong research background will be valuable in this regard,” says Prof Francis Petersen, Vice-Chancellor and Principal of the UFS. 

Prof Ngobeni is a member of several professional bodies in his field of expertise, including MatTEK at the Council for Scientific and Industrial Research (CSIR), the South African Chemical Institute (SACI), the Society for Atomic Spectroscopy, and the South African Council for Natural Scientific Professions (SACNASP). During his career, he has also secured research funding for individual projects and international partnerships. Prof Ngobeni also initiated chemistry practical sessions for local schools and participated in the Technology Station in Chemicals project, which offers a wide range of services designed to assist small and medium enterprises (SMEs) in the chemical sector.

His substantial list of publications in journals and books covers a range of chemistry-related and managerial topics. He is also a well-versed presenter at local and international conferences. 

“The Qwaqwa Campus has experienced major developments in recent years; I look forward to further contributing to the growth of the campus and to support the university in achieving its Vision 130,” says Prof Ngobeni.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
