The transportation sector, particularly heavy-duty trucking, plays a significant role in global carbon emissions. MIT researchers presented a study at the American Society of Mechanical Engineers conference addressing the need for a zero-emission trucking industry. The research quantifies the impact of energy storage requirements and operational revenue on the design of zero-emission trucks, providing insights for fleet owners. Challenges include the need for energy storage for range and towing performance, with hydrogen fuel-cell-electric vehicles demonstrating potential for longer routes. Government intervention through incentives and subsidies is seen as essential to make hydrogen-powered trucks economically viable. The study highlights the complex interplay between infrastructure, technological readiness, and cost considerations that must be addressed simultaneously for successful fleet transitions. MIT's efforts include tools to aid industry stakeholders in navigating decarbonization, emphasizing the importance of informed decision-making in the transition to zero-emission vehicles.
