An evaluation of the extent to which South African energy companies leverage Industry 4.0 technologies to improve efficiencies in comparison with China and Germany

Abstract

Four industrial revolutions have shaped the global production of goods and services and broader economic development. These revolutions have been disruptive and transformative yet created a continuum in production processes and societal change. The disruptive capacity of these revolutions was steered by scientific and technological discoveries such as the steam engine, electricity, and magnetism as a source of energy and quantum mechanics, as well as their influence on digital technologies. At the centre of each industrial revolution is the production of different types of energy and the technologies that produced them. While most economic activity is still driven by the technologies of the second and third industrial revolutions, the world is currently experiencing the fourth industrial revolution, known as 4IR or Industry 4.0. At the same time, with the inexorable growth in global Gross Domestic Product (GDP) still heavily reliant on fossil fuel-driven energy sources, global warming progresses unabated, notwithstanding heightened investments in renewable energy. In 2024, South Africa is the largest economy in Africa and the continent’s foremost electricity producer. To sustain its economy, South Africa must enhance the efficiency, sustainability, accessibility, and reliability of its energy production. Meanwhile, Germany and China are at the forefront of transforming their own energy sectors. Given South Africa's ongoing energy crisis, assessing how its energy sector compares to those of other countries is worthwhile. This research aims to evaluate the extent to which South African energy companies are utilising Industry 4.0 technologies, compare their usage to that in China and Germany, and the extent to which a limited uptake of such technologies may exacerbate challenges facing the South African energy sector. The study focuses on South Africa, China, and Germany. It includes a literature review, an online survey of 26 energy companies, and interviews with energy companies and industry experts, yielding exciting results. Global research on energy sector technologies predominantly focuses on the Internet of Things (IoT), Artificial Intelligence (AI), and Big, Real-Time Data (BRTD). In contrast, limited publications on Machine-Human Integration (MHI) and Robotics (ROB) exist. Part of this study examines the application of Industry 4.0 technologies by energy companies in China, Germany, and South Africa. Overall, survey results indicate that 85% of participants reported their company being a part of the Fourth Industrial Revolution. Additionally, 50% of companies declared their usage of these technologies as “very good” or “good,” whilst a third described such usage as “fair,” although few develop these technologies in-house. The most important, efficient, reliable, and integrable technologies, facilitate access to Big, Real-Time Data and data analysis. The Internet of Things also ranks highly for data transfer. However, Artificial Intelligence, Robotics, and Machine-Human Integration are considered less important, efficient, and reliable. Notably, China rates Industry 4.0 technologies as significantly more critical than South Africa and Germany. Interviews with energy and technology companies in South Africa, China, and Germany help determine the extent to which these companies leverage Industry 4.0 technologies and whether these contribute to efficiency in energy production. The Internet of Things and Artificial Intelligence amongst Chinese and German companies is at the forefront of their energy sectors, primarily to increase energy system efficiencies and facilitate the transition to an integrated energy sector. The development and use of Industry 4.0 technologies as an integral part of the energy system, has been spearheaded by the state through national policy, as part of a carefully constructed plan for the energy sectors of both China and Germany. Thousands of decentralised renewable energy producers and consumers in Germany are integrated into a flexible power system that produces a more stable power grid. In the case of China, the use of robots in mining, together with digitising the process of safety inspections, resulted in safer working conditions and improved worker satisfaction in its energy sector. Using a more centralised approach that incorporates the implementation and operationalisation of clear, national directives through State-Owned Entities, China is integrating Artificial Intelligence across the energy pipeline to more effectively manage demand and supply through forecasting. In South Africa, where Industry 4.0 technologies appear to be used incrementally, the constructive disruption of Artificial Intelligence on the energy sector has yet to be fully realised. For energy companies, constraints dominating the South African renewable energy sector that continue to slow down its digitalisation are high technology costs and insufficient political will. Even so, the companies in all three countries use Big, Real- Time Data and data analysis and Internet of Things platforms to flag operational and process- related concerns and perform preemptive maintenance, boosting plant efficiencies and increasing productivity. However, such usage within South African energy companies is limited and largely piecemeal, the result of the lack of a cohesive national policy framework for using Industry 4.0 technologies in South Africa's energy sector, particularly regarding a strategic approach to adopting Industry 4.0 technologies.
