A recent decarbonization report by Pollution Probe in collaboration with Delphi and Mobility Futures Lab highlights the gradual integration of Zero-Emission Vehicles (ZEVs) like Battery Electric Vehicles (BEVs) and Hydrogen Fuel Cell Electric Vehicles (FCEVs) into Canada's Class 8 long-haul trucking sector. While current ZEV models face range and payload limitations compared to diesel trucks, the report emphasizes the potential for future improvement with advancements in battery energy density, new chemistries, and infrastructure developments. BEVs and FCEVs are particularly suitable for LTL and regional operations, with prospects for growth in TL and long-haul applications through continued research and development investments. The report underscores the crucial need for advancements in battery technology and the deployment of megawatt fast-charging stations to address range limitations and payload issues. Additionally, it points out the necessity for substantial infrastructure investments to support ZEV deployment. For BEVs, this includes high-power charging systems, while FCEVs require hydrogen production facilities, distribution pipelines, and refueling stations. Moreover, the report emphasizes the significance of robust policies, incentives, and collaborations to accelerate ZEV adoption. Tailpipe emissions regulations, sales mandates, and financial incentives are identified as key drivers in closing the cost gap between ZEVs and Internal Combustion Engine (ICE) trucks. Fleet operators are encouraged to engage in pilot projects to gain insights into ZEVs' operational capabilities, collaborate with stakeholders, and align infrastructure development with industry needs. Despite the challenges, transitioning to ZEVs offers benefits such as government incentives, potential cost savings, and reduced emissions as technology matures.
