A study of the transition from diesel trucks to electric trucks in the mining sector in South Africa

Abstract

Diesel is the primary energy source for many mining applications. Still, it has significant drawbacks, including high operating costs, air pollution, and greenhouse gas emissions, all of which pose risks to human health and the environment. Mining companies should consider alternative energy solutions to address these environmental concerns, such as battery electric trucks. These technologies could offer several benefits, including lower operating costs, reduced emissions, and improved worker health and safety. This study aimed to explore replacing diesel trucks with battery electric trucks in the underground mining sector in South Africa to help these companies meet decarbonisation and emission goals. By transitioning to battery electric trucks, the mining sector reduces its carbon footprint and enhances its sustainability and social responsibility, aligning with the global efforts to combat climate change. It is important to note that transitioning to clean energy technologies can be costly and will require government support through regulations, grants, and collaboration with other stakeholders such as original equipment manufacturers. This study’s uniqueness lies in its approach to gathering both qualitative and quantitative data involved in transitioning from diesel trucks. The study investigated the use of trucks in underground mining, more specifically the environmental impact of diesel trucks compared to battery electric trucks, the economic viability of adopting battery electric trucks, as well as the barriers to the adoption of electric trucks. The analysis was based on data collected from secondary sources. The main findings showed that the use of electric trucks in underground mining is better for the environment; furthermore cost parity of battery electric trucks could be achieved in the next three to five years and to encourage the adoption of this new technology, the government has a key role to play.
