BHP has taken a significant step towards reducing its carbon footprint by deploying its first electric excavator, the R 9400 E Liebherr, at the Yandi iron ore mine in Pilbara, Western Australia. This move is part of the company’s broader strategy to decarbonize its operations, focusing on electrifying its fleet to reduce greenhouse gas (GHG) emissions.
Unlike traditional excavators powered by diesel engines, the R 9400 E is equipped with an electric motor. The necessary power is supplied through a trailing cable connected to an autonomous cable reeler, enabling the excavator to operate without the need for diesel fuel. This advancement is a critical component of BHP’s goal to cut operational GHG emissions (Scopes 1 and 2 from operated assets) by at least 30% by FY2030, based on adjusted FY2020 levels. The ultimate aim is to achieve net-zero operational GHG emissions by CY2050.
Tim Day, Western Australia Iron Ore (WAIO) Asset President, emphasized that the electrification of BHP’s fleet is a priority in the company’s efforts to reduce its reliance on diesel. “From trucks to trains to excavators, we’re working hard to electrify our equipment,” he said, highlighting the importance of this transition in meeting BHP’s medium- and long-term environmental goals.
BHP’s strategy to decarbonize its mining equipment involves replacing diesel with renewable electricity or other low to zero GHG emission power sources. However, the challenge in Western Australia is that the WAIO is not connected to an existing power grid, making the introduction of large volumes of renewable energy a complex task. BHP is currently exploring the best solutions to overcome this hurdle and ensure a steady supply of renewable energy to power its operations.
The introduction of the R 9400 E Liebherr electric excavator marks a significant milestone in BHP’s journey towards sustainability. By investing in electric machinery, BHP not only reduces its environmental impact but also sets a precedent for the future of mining operations worldwide. The shift to electric equipment is crucial in addressing the environmental challenges faced by the mining industry, and BHP is leading the charge.
As the industry moves towards greener solutions, BHP’s commitment to electrification and renewable energy will likely inspire other companies to follow suit, ultimately contributing to a more sustainable future for mining.
