Abstract: From phones to fighter jets, a range of devices and machines rely on rare earth elements that are mined and refined largely in China. Rare earth elements are vital to national security and decarbonizing our economy by 2050. The supply of rare earth minerals can be cut by natural disasters, mine closures, labor disputes, construction delays. Disruptions can have wide-ranging consequences. And such turmoil can linger in the rare earth markets for longer than we expect, as today’s shortage of semiconductors continues to roil the car market. In this webinar, Allison Bennett Irion, chair of Argonne’s Advanced Supply Chain Analytics initiative, will show how her team finds such insights by running one-of-kind models on the lab’s supercomputing resources.
