The transportation sector's contribution to global CO2 emissions necessitates decarbonization, particularly in heavy-duty trucking. A study by MIT researchers presented at a conference explores the impact of design choices on energy storage and operational revenue of zero-emission trucks. The model aids fleet owners in understanding the economic feasibility of battery-electric and hydrogen fuel cell trucks, highlighting challenges such as energy storage requirements and infrastructure upgrades. While battery-electric drivetrains are limited to short ranges due to storage needs, hydrogen fuel cell vehicles offer higher cargo capacity for longer routes but face economic hurdles. Government intervention and technology advancements are pivotal for successful adoption of alternative drivetrains. MIT's efforts, including an interactive mapping tool, support stakeholders in navigating the complexities of decarbonization. Collaboration and joint problem-solving across sectors are crucial for a sustainable transition, with stakeholders showing readiness to address climate challenges together.
