What's Happening?
Global mining services company Thiess has announced plans to retrofit a Caterpillar 793D haul truck with a hybrid kit developed in collaboration with FLANDERS. This initiative is part of Thiess's ongoing efforts to reduce emissions and support the energy
transition within the mining industry. The company has acknowledged the challenges in achieving net-zero emissions with current technologies and is focusing on interim solutions like hybrid retrofits. In 2025, Thiess and FLANDERS completed key planning and risk assessments for the hybrid retrofit, with installation scheduled for 2026. The trial will take place in New South Wales, Australia, and aims to validate the performance and viability of the hybrid technology. If successful, the technology will be implemented on a full production circuit of trucks in Queensland.
Why It's Important?
The retrofit of the Caterpillar 793D with a hybrid kit represents a significant step towards reducing emissions in the mining industry, which is traditionally reliant on diesel-powered equipment. By focusing on hybrid solutions, Thiess is addressing the gap between current decarbonization targets and the availability of fully electric or hydrogen-powered mining fleets. This initiative could lead to substantial reductions in fuel consumption and emissions, with pre-trial models suggesting a 16% reduction in emissions per truck. The success of this trial could set a precedent for other mining companies to adopt similar technologies, potentially accelerating the industry's transition to more sustainable practices.
What's Next?
Following the installation of the hybrid kit in 2026, the trial will assess the performance and viability of the technology. If the trial is successful, Thiess plans to implement the hybrid technology on a full production circuit of trucks in Queensland. This could demonstrate the broader industry benefits of hybrid retrofits and encourage other companies to adopt similar solutions. The trial's outcomes will likely influence future decisions on emissions reduction strategies within the mining sector, potentially leading to wider adoption of hybrid technologies as a bridge to fully electric solutions.
