"Our ambition to reach net zero emissions across our operations is a priority. Reaching this ambition will require new and innovative solutions and partnerships with supplier partners like Caterpillar. This collaboration represents a small but important step on that journey," Rio Tinto chief commercial officer Alf Barrios said.
"We look forward to working together to validate these zero-emissions haul trucks in just a few years' time. The advanced technology at Gudai-Darri puts it at the forefront of new mining operations globally and we look forward to adding Caterpillar zero-emissions haul trucks to the site."
In June, Rio Tinto worked with Caterpillar to deploy three fully autonomous water trucks at its Gundai-Darri site. Each truck features an on-board system that can automatically detect when water application is needed on the roads to suppress dry and dusty conditions on-site. It can also recognise when it is time to refill, prompting them to self-drive to the water stand, park, and top-up before returning to the field.
