Evaluating critical materials supply risks is a rapidly increasing need in industry. The demands for clean energy, including transportation technologies for decarbonizing the economy, have taxed the availability of important materials. This dependence introduces supply chain vulnerabilities and jeopardizes the U.S.’s energy decarbonization goals. Argonne delivers advanced dynamic modeling tools for securing supplies, continually evaluating the stockpile requirements and analyzing supply chain pricing and availability in many clean energy sectors.
