Global Tech Giants Revolutionize Mining with Electric Haul Trucks





In response to the escalating global demand for battery minerals, major tech companies such as ABB, Hitachi, Komatsu, and Sumitomo have united to devise an innovative technological strategy aimed at reducing emissions within Japanese mining activities. This collaboration has resulted in the creation of a fully electric 240-ton haul truck designed for extreme mining conditions. The project reached a pivotal milestone last year with the completion of its first prototype and is now operational at the Kansanshi copper-gold mine in Zambia. This pilot program represents the first manufacturer-led trial of such electric vehicles under real-world mining scenarios.
The partnership between Hitachi Construction Machinery and ABB Traction began with the development of a massive electric haul truck. Over the past year, additional support from Komatsu and Sumitomo expanded the initiative's scope. Fabiana Cavalcante, Head of Mobile e-Power at ABB Traction, expressed excitement about this critical step forward, emphasizing the project's role in addressing challenges related to dump truck electrification while contributing to a low-carbon future. At the recent Electric Mine Conference in Chile, discussions highlighted not only the transition of heavy haul trucks to electric systems but also the implementation of a "trolley-style" overhead charging system that allows continuous operation without the need for downtime.
This advanced three-part system employs high-capacity batteries for level ground operations, draws supplementary power from overhead wires during uphill climbs, and utilizes regenerative braking on downhill runs to recharge the batteries. Such a setup ensures nearly uninterrupted operation, significantly enhancing efficiency in mining processes. According to projections by the International Energy Agency (IEA), the demand for minerals used in electric vehicles is expected to grow thirtyfold between 2020 and 2040, with lithium and nickel seeing even more substantial increases. As the world moves away from diesel reliance, the decarbonization of mining operations becomes increasingly vital.
The ultimate goal involves converting Hitachi’s fleet of 2500 HP EH4000 diesel mining trucks to electric drive systems. Interested parties can explore further details through ABB's conceptual launch video from last year, which provides a CGI-based overview of the eMine process. This collaborative effort marks a significant advancement in sustainable mining technology, demonstrating the potential for cleaner, more efficient extraction methods.
As the global shift towards renewable energy sources accelerates, the importance of minimizing environmental impact in resource-intensive industries like mining cannot be overstated. These developments highlight the commitment of leading tech companies to innovate and lead the way toward a more sustainable future, setting a precedent for others in the industry to follow suit.
