Rising demand for nickel, lithium, and phosphates combined with the natural benefits of electrification are driving the adoption of electric mining machines. At the same time, a persistent operator shortage is boosting demand for autonomous machines.
The IEA’s projections take several battery development scenarios into consideration, and include increasingly familiar terms like utility-scale battery energy storage. All of which is to say: they seem like thoroughly conceived and well-executed projections, with nothing obviously squirrely happening in the scaling or anything like that (#pythonistas).
A delayed shift to nickel-rich chemistries (and away from cobalt-rich chemistries) results in nearly 50% higher demand for cobalt and manganese in 2040 compared to the base case. Nickel demand is 5% lower in 2040 compared to the base case.
The faster uptake of lithium metal anodes and ASSB results in 22% higher lithium demand in 2040 compared to the base case, but also much lower demand for graphite (down 44%) and silicon (down 33%).
Moving rapidly towards a silicon-rich anode results in nearly three times as much silicon demand in 2030 compared to the base case, and a slight decrease in graphite demand (down 6%). By 2040 silicon demand is only 70% higher, owing to a higher adoption of silicon-rich anodes even in the base case.
So, there’s more demand for stuff that’s mined. That means there will be more mines, and more mining, but not necessarily more people willing to go down into those mines. That labor shortage, coupled with stricter safety regulations and the increasing threat of high-dollar lawsuits resulting from workplace injuries, practically invites more automation into the space.
The remote locations of mines and the repetitive nature of the work also invites automation. “A mining vehicle typically travels the same route or makes the same movements over the course of the day, such as digging and loading material into a vehicle,” writes Sara Jensen, at Power & Motion. “This aids the design of an autonomous system because there are known patterns which can be more easily integrated compared to the varied drive cycles of on-road vehicles.”
Big players spending big money
It should come as no surprise, then, that the race is on to bring practical, electric, and autonomous heavy mining equipment to market. At CES this past year, autonomous electric equipment from Hyundai, Bobcat, Volvo CE, and Caterpillar garnered lots of attention with their innovative concepts (above) – and for good reason.
