BHP will purchase four battery-electric locomotives and conduct trials at its Western Australia Iron Ore rail network, as part of the company’s ongoing efforts to reduce its operational emissions. The four locomotives are scheduled for delivery in late 2023. Two will be supplied by BHP’s current provider Progress Rail, a Caterpillar company, and two from Wabtec. BHP will test the battery-electric locomotives’ performance and emissions reduction capabilities in delivering iron ore from its Pilbara mines to the Port Hedland export facility. Conducting the trials in collaboration with two leading providers will support BHP’s planned electrification of its iron ore fleet of more than 180 locomotives. A full transition to battery-electric locomotives would reduce BHP’s WA iron ore diesel-related carbon emissions by approximately 30 per cent annually.The trials will also test unique ‘energy recapture’ opportunities using the rail network’s natural topography to further reduce the trains’ overall power demand. On the way to port, locomotives can capture energy from braking on downhill slopes (energy that would otherwise be lost) and use it to help power empty trains back to the Pilbara.A fully-laden BHP WA Iron Ore train typically comprises four diesel-electric locomotives pulling approximately 270 cars carrying a total of 38,000 tons of iron ore.Progress Rail, a Caterpillar company, is one of the largest integrated and diversified providers of rolling stock and infrastructure solutions and technologies for global rail customers.
