Kaunis Iron is now collaborating with Vattenfall, Volvo Trucks, ABB and Wist Last & Buss in a unique pilot project to develop a sustainable logistics system for the future with electrically powered heavy trucks functioning in 44 degree Celcius below zero in northern Sweden. The project is part of the letter of intent recently signed by Kaunis Iron and Vattenfall to develop electrified fossil free mining operations. One of the biggest challenges in achieving that goal is to reduce carbon dioxide emissions from the heavy transports of the ore, that take place via trucks in the first stage before trains take over. A comprehensive study of different alternatives has led to a pilot test with fossil free electrical power. Now a collaboration cluster has been started to put in place a pilot test on site in Pajala, north of the Polar circle in Sweden.
Volvo Trucks is contributing with its own heavy truck, an all electric Volvo FMX prototype, to evaluate how battery electric trucks including charging systems function in Arctic conditions. Part of the testing includes the charging infrastructure, which must efficiently manage charging the truck in the operational cycle.
