World mining providers firm Thiess has revealed its 2025 Sustainability Report, during which it says it continues to refine its pathway to emissions discount, “acknowledging that commercially viable applied sciences able to powering massive mining fleet to attain web zero emissions are nonetheless in improvement.”
It says the broader power transition is advancing at a slower tempo than anticipated, pushed by rising international power demand, delayed deployment of enabling infrastructure and the technical problem of broad-scale diesel displacement.
The Thiess Group, nonetheless, recognises its place in offering mining providers for a lower-carbon future, and its duty in serving to allow the power transition. “We acknowledge the present constraints related to the operation of a completely electrical or hydrogen powered mining fleet and are centered on supporting our purchasers with economically viable decarbonisation pathways.”
In 2025, Thiess continued investigations into decarbonisation options, nonetheless, it sees a spot between business decarbonisation targets and the possible timeline for viable business implementation of lower-emissions mining options. Due to this fact Thiess Group is specializing in interim applied sciences to bridge this hole. And a key focus space is agnostic hybrid options to swimsuit present diesel and diesel-electric mining tools.
Thiess: “Agnostic hybrid options supply the flexibility to technology-stack with different market options as these turn out to be commercially out there. The present business desire to increase the lifetime of property by way of zero hour rebuilds presents Thiess a possibility to put in hybrid kits on OEM vans whereas finishing rebuilds for our enterprise, present purchasers and broader markets.”
In 2024, Thiess entered a Memorandum of Understanding with FLANDERS to give attention to supply of diesel-mechanical hybrid retrofits as a present cost-effective emissions discount answer. In 2025,
Thiess and FLANDERS progressed their mechanical hybrid retrofit initiative, finishing key parts of set up planning, threat evaluation, compliance critiques and detailed trial design.
Collectively in 2025, Thiess and FLANDERS developed a trial to check hybrid retrofit expertise on a Cat 793D haul truck in New South Wales, Australia. They purpose to collaboratively set up the hybrid package in 2026, then to run it for a trial interval to validate asset efficiency and product viability. Pending profitable trial outcomes, the workforce suggest to implement the expertise on a full manufacturing circuit of vans in Queensland to reveal business advantages.
Pre-trial modelling signifies gasoline consumption and emissions needs to be lowered by roughly 16%, equating to 360 tCO2-e saved per 12 months per 230-tonne class truck. Moreover, the expertise ought to present a rise in most velocity and acceleration. Below appropriate undertaking circumstances this could end in improved cycle instances. Thiess: “The purpose is to offer this bridging expertise to our prospects till a full battery-electric answer turns into commercially out there.”
