Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050.
Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050.

Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050. The energy mix by 2050 is focused on renewables and the long-term journey is very clear: we have to be renewable driven.

This is according to panellists speaking at the University of the Free State’s (UFS) third webinar in the 2022 Thought-Leader webinar series. The webinar titled, What needs to be done to POWER up South Africa? comprised panellists Matthew Mflathelwa, General Manager: Strategy and Planning at Eskom; Steve Nicholls, Head of Mitigation at South Africa’s Presidential Climate Commission (PCC); Happy Khambule, Environment and Energy Manager at Business Unity South Africa (BUSA); and Louis Lagrange, Head: Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences, UFS. 

We need to invest in new infrastructure

In his presentation, Mflathelwa talked about how Eskom can unlock additional grid capacity and how to start rolling out business models to enable this transition. 

“On the demand side, we are looking at some exciting and interesting initiatives. We are looking at how we can start to aggregate or leverage the idea of consumers becoming prosumers, and leverage technology to aggregate the potential supply and management demand from that perspective.” 

“The question is also how to do this sustainably in the long term. We need to invest a considerable amount of new infrastructure,” said Mflathelwa. 

According to him, it is not a secret that most of Eskom’s generating assets are approaching the end of life. The question now is how to proactively plan for this to ensure that we address the problem of load shedding sustainably. “The big takeaway is that there is a significant amount of new capacity that needs to be built and this is predominantly going to be renewables, but it is not the only additional infrastructure that is required. We need an energy mix that can respond and achieve adequacy for the future requirements.”  

Another important element that is often neglected is the transmission of grid infrastructure, given the penetration or entry of new players with greater penetration of renewable energy and the advantages that come with distributing these energy sources across the country. There is a lot of transmission and distribution infrastructure needed to enable this future capacity.

Some of the things also being discussed, said Mflathelwa, are how to enable greater and faster penetration of new capacity – specifically renewables to aid in the reduction of environmental challenges.

What needs to be done to POWER up South Africa 
(Recorded on 27 September 2022)

 

The next decade is critical 

Nicholls gave a climate-friendly perspective on the work that Eskom is doing, saying energy transition in SA is core to the overall economy transition and getting a zero-carbon, least-cost energy system is fundamental to the strategy of the country. 

“We need to move from carbon emissions of around 480 megatons per annum today to somewhere between 350 and 420 by 2030, and then onto zero carbon emissions by 2050. If South Africa is to reach net-zero by 2050, we need targeted investment between now and 2030, setting the stage for accelerated investment in decarbonisation post 2030. The next decade is critical. Given the state of South Africa’s balance sheets, international support and foreign direct investment are critical.”

Nicholls said the energy mix by 2050 is really focused on renewables, and the long-term journey is very clear: we have to be renewable driven. The short- and long-term solutions are alike; renewables are cheaper, quicker to get onto the grid, pending some investment in the grid.   

“In the long term, we need big investments in renewables – about 6 GW a year between now and mid-2050. We need a big investment in the transmission grid. Hydrogen plays a critical role in decarbonisation of power and industry. Energy efficiency is key. It’s really the unsung hero in this conversation. If we can be energy efficient, we can take two power stations off the grid and that makes a big difference in terms of affordability.” 

“Transport is also important; if we are going to be a net-zero economy, we have to fully electrify the transport fleet, which puts an extra load on what Eskom needs to achieve,” Nicholls said. 

Energy efficiency is most critical

Khambule emphasized that the country needs to focus on using energy in an efficient manner in the commercial and household sectors, as energy efficiency is critical to the country’s power supply issues in the short term. According to Khambule, the country is not using energy in an efficient manner.

"If we are able to use power the minute it is necessary and become more efficient with it, we can get more value out of that power," said Khambule.

Lagrange concurred with Khambule on the importance of energy efficiency, referring to it as ‘the unsung hero’. “Energy efficiency is the biggest solution that we can have, and people need to be trained on how to use energy efficiently,” said Lagrange.

Khambule also addressed the issue of power cuts, saying the unpredictability thereof, even in the short-term, further exacerbated the situation.

"The unpredictability of load shedding has become much more of a driver for uncertainty, which leads to a lack of business confidence, and secondly leads to losses in production;  a key notion is that if we have predictability of load shedding, planning can be undertaken, and if planning is undertaken in a more judicious manner, then we are at least able to keep the losses at a minimum and see how we can weather the storm until a sustainable supply can be implemented."

Khambule also added that in the short and mid-term, solutions must consider protecting or mitigating options for vulnerable sectors. “In some industries – such as health care, power is essential and there is a need for predictable supply. Therefore, some sectors will require mitigating solutions to protect some essential sectors,” said Khambule.
According to Lagrange, no amazing technology for the generation and distribution of energy has been developed over the past decade. “We need to reimagine the entire current regulatory systems business model, because it is caught up in an energy stagnation, which is frighteningly fragile from a physical and cyber-security point of view,” added Lagrange.

During 2011: Prestige Scholars Programme (PSP)
2011-12-01

The University has designed the Vice-Chancellor’s Prestige Scholars Programme (PSP) to promote and support the intellectual breadth and depth required of young scholars to pose questions and generate knowledge in their disciplines and hence to occupy the vanguards of contemporary intellectual enquiry. The programme specifically targets members of the academic staff who are near completion, or have newly completed, their doctoral studies.

The goal is to select no more than 100 of the most promising young scholars and to make substantial investments in their development towards becoming full professors. A tailored, intensive programme of support is designated that combines international placement working alongside leading scholars in the discipline of the prestige scholar, with intensive mentorship and support from within the university.

Elite young scholars on the Vice-Chancellor’s Prestige Scholars Programme generated R1,2 million in National Research Foundation Thuthuka and Blue Skies funding in 2011 alone. Dr Katinka de Wet in the Department of Sociology was awarded Blue Skies funding for her work on the Hybrid Identity of the HIV/Aids patient. Thuthuka Grant holders Drs Cilliers van den Berg, Olihile Sebolai, Dirk Opperman and Diaan van der Westhuizen work in the fields of German and Afrikaans trauma literature, microbiology, structural and evolutionary biology, and architecture, respectively. This broad disciplinary range typifies the depth and extraordinary range of scholarship present among junior academics at the UFS.

Dr Olihile Sebolai is one of the 2 Vice-Chancellor’s elite Prestige Scholars and a microbiologist. In 2011, Dr Sebolai was awarded a Thuthuka Grant for his research on the yeast pathogen Cryptococcus neoformans, the cause of life-threatening Aids-defining illnesses such as meningitis. Dr Sebolai considers how cryptococcal lipids mediate infectious processes leading to illness. An understanding of these cellular processes will offer hope for future drug development to combat the scourge of cryptococcal meningitis, annually causing the death of over half a million people in Sub-Saharan Africa. Dr Sebolai is also interested in mapping the prevalence and distribution pattern of cryptococcal meningitis in the Free State. This, in turn, will assist health authorities to manage current infections and plan appropriately for potential outbreaks. The Prestige Scholars Programme, with the assistance of the National Research Foundation, will afford Dr Sebolai the opportunity to pursue his research in laboratories in the United States and India in 2012 and 2013.

Dr Lizette Erasmus, scientific chemist and one of the Vice-Chancellor’s Prestige Scholars, has just returned from a three-month-long research visit to Prof. Hans Niemantsverdriet at the Technical University of Eindhoven in The Netherlands and the University of California, Davis. Dr Erasmus specialises in heterogeneous catalysis. Her visit to Prof. Niemantsverdriet, one of the global experts in the field of surface science, served to round of existing research. In California, Dr Erasmus visited her mentor, Prof. Bruce C. Gates, as part of the objectives of the Rector’s programme for the internationalisation of young researchers. Prof. Gates, an expert in catalysis, could contribute to Dr Erasmus’ research on the characterisation of heterogeneous catalysis and catalytic reactions. In exchange, her expertise in organometallic synthesis added value to Prof. Gates’ existing research. Their continued collaboration gave availed them of the opportunity for interdisciplinary interaction between engineering (Prof. Gates’ speciality) and chemistry, and promises to contribute to increased collaboration between the two universities in future.
