In Canada and across the world, commercial vehicles are central to economic activity but are responsible for significant greenhouse gas emissions. Substantially reducing the climate impacts of goods transport without increasing costs is a major challenge. Combining existing engine technology with clean-burning fuels and a high-efficiency hybrid-electric powertrain offers a promising near-term approach to address this pressing problem. In this project, experts from the University of Alberta and Simon Fraser University will collaborate with Vancouver-based Westport Fuel Systems Inc. to investigate the potential emissions and fuel consumption benefits of a hybrid-electric commercial vehicle fueled with a range of low-carbon gaseous fuels. The project will involve detailed modelling and optimization of the electric drive system, internal combustion engine, and on-board energy storage. The project will target a medium-heavy duty truck combined with a low-cost, high-efficiency natural gas engine as the main power source. The engine size and combustion system will be carefully optimized to match the required performance of the hybrid-electric powertrain. Simultaneously, the powertrain will be configured to make best use of the power provided from the engine while following the target drive profile. The additional benefits for both tailpipe and net greenhouse gas emissions from renewably generated gaseous fuels, such as bio-gas or hydrogen, will also be assessed. The results from this project will be the structural design of a commercially viable powertrain system that can provide dramatic reductions in greenhouse gas emissions for commercial transport.

在加拿大和世界各地，商用车是经济活动的核心，但也造成了大量的温室气体排放。在不增加成本的情况下大幅减少货物运输对气候的影响是一项重大挑战。将现有发动机技术与清洁燃料和高效混合动力系统相结合，有望在短期内解决这一紧迫问题。在这个项目中，来自阿尔伯塔大学和西蒙弗雷泽大学的专家将与总部位于温哥华的西港燃料系统公司合作，调查使用一系列低碳气体燃料的混合动力商用车的潜在排放和燃料消耗效益。
