A recent study from McMaster University in Hamilton suggests that transitioning all buses in Canada to electric power could be achieved at a reasonable cost and have a minimal impact on the country’s power generation. Researchers Moataz Mohamed and Hatem Abdelaty highlighted that such a nationwide shift would significantly reduce greenhouse gas emissions. Despite concerns about the expenses involved, Mohamed emphasized the feasibility of electrification for transit systems, citing declining battery costs as a key factor.
The study revealed that transitioning to electric buses, especially for scheduled transit operations, is highly suitable due to the predictable nature of bus routes and charging requirements. With an analysis based on publicly available data, the research team projected the costs, electricity demands, and emission reductions associated with national bus electrification.
One crucial finding was that increasing the fleet size to accommodate longer charging times for electric buses would be a major cost component, amounting to approximately $1.73 billion. The total annual cost of electrification, including electricity and emissions-related expenses, was estimated at around $1.94 billion. While this projection did not include potential distribution-related costs, Mohamed noted that long-term operational savings could offset initial investments.
According to the study, national bus electrification would necessitate an additional 1.255 terawatt-hours of electricity annually, representing only 0.20% of Canada’s total electricity generation. This shift would result in a substantial 93% reduction in greenhouse gas emissions, from 1.77 million tonnes of carbon dioxide to 129,747 tonnes.
Although formal plans for electrification are not yet in place for Hamilton Street Railway (HSR), the transit service is considering alternatives like battery electric buses and hydrogen fuel options. While upfront costs remain a challenge, potential strategies include working with experts to conduct feasibility studies. The broader impact of emission-reduction efforts in Hamilton could be influenced by ongoing budget discussions among city councillors.
In light of the study’s findings, Mohamed emphasized the importance of considering financial incentives and addressing logistical challenges in transitioning to electric buses. He expressed a desire for public funding to support pilot projects that can provide valuable data for future electrification initiatives. Ultimately, Mohamed envisions a future where electric buses are a common mode of transportation for generations to come.
