BHP has unveiled plans to trial energy transfer technology from Caterpillar, marking a significant step towards sustainable mining operations.
The Cat DET system, which can power both battery electric and diesel electric large mining trucks, will be tested at various BHP sites.
Caterpillar’s Cat DET system is designed to facilitate energy transfer to mining trucks during operation and can charge electric haul truck batteries while in motion.
Its flexible infrastructure is also easily relocatable, offering an advantage over traditional fixed overhead trolleys.
The upcoming trials stem from more than two years of alliance between BHP and Caterpillar, focused on sustainable energy transfer solutions.
These trials will validate the technology in BHP's iron ore and copper businesses, including the CAT 793 fleet at Jimblebar and the CAT 798 fleet at Escondida.
BHP chief commercial officer Ragnar Udd said: “We are pleased to be able to trial the DET technology that Caterpillar has developed, and it is a welcome addition in our plans to enable zero-emissions mining truck deployment at BHP.
“Innovation and technology will play a crucial role as we work towards BHP’s goal of net-zero operational emissions by 2050, and we are determined to keep building partnerships like this to achieve this objective.”
BHP also plans to integrate the Cat DET system with Cat autonomous solutions.
Caterpillar Group president Denise Johnson said: “BHP has been part of our Early Learner programme from the beginning, providing valuable feedback. We look forward to continuing that collaboration as we work together to trial the Cat DET system on both diesel electric and battery electric trucks at BHP’s sites.
“This is an important next step to validate the crucial energy management solutions needed to support not only BHP and Caterpillar but also the broader mining industry.”
In 2021, BHP announced a partnership with Caterpillar to introduce zero-exhaust emissions mining trucks at its sites, with the aim of reducing operational greenhouse gas emissions.
