Cradle-to-grave Life Cycle Assessment of Zero-emission Heavy-duty Trucks

Wednesday, November 9, 2022

Location: RGL215

Heavy duty trucks are a leading contributor to global climate change. California has
enacted technology forcing legislation to replace fossil fuel trucks with zero emission vehicles to
address freight transportation emissions. These vehicles include both battery electric and hydrogen
fuel cell class 8 trucks. To determine which type of vehicle provides the most significant savings in
energy consumption and emissions over diesel, a cradle to grave life cycle assessment (LCA) using
Argonne National Laboratory’s AFLEET and GREET tools explores energy and emissions of different
truck powertrains. The analysis includes upstream raw material and mineral extraction,
manufacturing, distribution, operation, end of life recycling/disposal, and the fuel production phase
of electric, hydrogen fuel cell, and diesel models. From this method, stage, place, or materials
assessment can reduce energy consumption and GHGs. Results from the LCA modeling suggest that
battery electric powertrains are superior at reducing the lifecycle carbon footprint more than a
comparable hydrogen fuel cell model using standard hydrogen producing methods. Significant
investments in renewable green hydrogen production are needed to make fuel cell technology a
viable option.
