| Abstract Scope |
This talk will explore and quantify the forward-looking opportunity space for lightweight materials substitution in battery electric vehicles, with an outlook from today to 2050. Foundational to the analysis is a dataset consisting of vehicle information for over 250 model year 2018-2023 battery electric models sold in the United States. A top-down statistical approach is applied to assess sustainable materials development opportunities from a life cycle perspective, considering both vehicle-cycle (materials) and fuel-cycle (electric vehicle charging) impacts on net greenhouse gas emissions. Impacts of materials selection and recycled content will be discussed—including sensitivity of results to the electric grid and vehicle characteristics such as size and drive range. We demonstrate that lightweight and sustainable materials development for electric vehicles can be a key part of an overall strategy to meet economy-wide decarbonization goals. However, net emissions outcomes depend on specific material selections and manufacturing methods. |
