A recent study conducted by researchers at McMaster University in Hamilton, Canada, suggests that the country could transition all buses to electric power at a reasonable cost without significantly impacting power generation. The move would result in a substantial reduction in greenhouse gas emissions, according to the study’s authors, Moataz Mohamed and Hatem Abdelaty.
Despite concerns about the costs involved, Mohamed, a professor at McMaster University, emphasizes the feasibility of electrification in public transit. He highlights the benefits of electrifying transit systems, citing the predictability of bus schedules and the decreasing costs of batteries.
The research, published in the journal Scientific Reports, outlines the potential for national bus electrification and the associated costs. The study estimates that Canada would require 17% more electric buses than the current fleet of diesel, hybrid, and natural gas buses.
The cost of transitioning to electric buses, estimated at $1.94 billion annually, includes fleet expansion costs and electricity expenses. While the initial investment is substantial, the researchers argue that the long-term benefits, such as reduced emissions, outweigh the costs.
The study projects that national bus electrification would increase electricity consumption by 1.255 terawatt-hours annually, which represents only a small fraction of Canada’s total electricity generation. Furthermore, the transition to electric buses could lead to a significant reduction in greenhouse gas emissions, from 1.77 million tonnes to 129,747 tonnes.
In Hamilton, where the study was conducted, the local transit agency, Hamilton Street Railway (HSR), is contemplating electrification but has not formalized any plans. Despite the upfront costs associated with electrification, HSR is monitoring developments in electric and hydrogen fuel technologies.
While the financial implications of transitioning to electric buses remain a concern, Mohamed suggests that financial incentives and public funding could facilitate the process. He emphasizes the importance of sharing knowledge and data to pave the way for a more sustainable future in public transportation.
Ultimately, the decision to electrify bus fleets rests with policymakers, but Mohamed hopes that ongoing research and public support will contribute to a cleaner and more efficient public transit system for future generations.
