Fortescue is making strides towards eliminating fossil fuels at its mining operations in the Pilbara by 2030, with the unveiling of the first of its two battery locomotives. The company plans to replace its diesel fleet with 70 battery-powered trains, generating regenerative power but requiring topping up at the port. Fortescue is also exploring various battery technologies, such as solid state, sodium ion, and different lithium ion chemistries, to improve the efficiency of its electric locomotives. The company aims to transition its entire fleet to electric vehicles and equipment, alongside building multiple gigawatts of wind and solar energy, and up to 5 gigawatt hours of battery storage. Challenges with battery capacity and energy density are being addressed as Fortescue tests the performance of the locomotives at the Thomas railway yard in Port Hedland.
