CobaltREE: Sustainable EV Supply Chain Guide

Sustainable EV Supply Chain Guide
Technology No. CW-22-54

The Cobalt and Rare Earth Global Supply Chain Analysis Model (CobaltREE) is a thorough tool crafted to investigate the link between cobalt and rare earth supply chains in clean energy technologies, particularly electric vehicles (EVs) and wind energy. Using the robust System Dynamic model built on the Vensim DSS 9.2.3 platform and later converted to Stella for a more user-friendly interface, CobaltREE simulates market dynamics from 2005 to 2050, examining the impact of magnet substitution and evaluating various scenarios to meet aggressive EV deployment goals. It seeks to identify key constraints to EV deployment, explore improvements in the cobalt or rare earth supply chain, and determine market conditions that could enable global EV sales goals to be met. This cutting-edge software tool is highly advantageous for EV manufacturers and investors, as it furnishes invaluable insights that could direct production choices and investment policies, considering supply chain impediments such as the persistent lack of cobalt.
