The race to electrify heavy trucks is heating up, and it's not just about hydrogen anymore. While hydrogen fuel cells have long been touted as the solution to decarbonizing heavy vehicles, recent developments suggest that battery-electric trucks are quickly gaining ground. So, what's the verdict? Is hydrogen's reign over as the preferred technology for heavy-duty transportation coming to an end?
The Hydrogen Advantage
Hydrogen fuel cells have always had a certain allure for heavy trucks. They offer a higher energy density and faster refuelling times compared to batteries, which is crucial for long-haul trucking. The weight of batteries would require a reduction in the load that is unacceptable to operators, according to Canada's Hydrogen Strategy. This strategy, released in 2020, projected that transportation would account for 13% of hydrogen demand in Canada by 2050, with fuel cells playing a significant role in trucking.
The Battery Revolution
However, the battery-electric revolution is changing the game. China, a key player in this arena, has been a driving force behind the adoption of battery-electric trucks. With high diesel prices and an expanding charging infrastructure, including battery swapping stations, China has seen a surge in electric truck sales. In 2025, about 35,000 fuel cell trucks were in the world, with 95% of them in China, according to the International Energy Agency (IEA). China now has around one million electric trucks, and sales nearly tripled last year to 230,000, with a focus on heavy freight trucks.
The Economic Case for Batteries
The economic case for battery-electric heavy-duty trucks is becoming more compelling. While battery trucks are currently more expensive upfront, their fuel costs are significantly lower. This is a crucial factor for long-haul trucking, where fuel expenses can be substantial. Nikita Pavlenko, the director of the fuels and aviation program at the International Council on Clean Transportation, highlights the cost improvements in battery technology, which have allowed manufacturers to extend the range without a proportional price increase.
Hydrogen's Challenges
Hydrogen trucks, on the other hand, face several challenges. The hydrogen itself is very expensive, and the fuelling infrastructure is costly to build and maintain. Sinopec, a Chinese state-owned oil and gas company, has invested in both technologies but acknowledges that hydrogen trucks must differentiate themselves from battery counterparts. Most battery-electric trucks have been deployed on shorter routes, and long-haul trucking requires stronger, cheaper, and lighter batteries.
The Future of Hydrogen?
Despite these challenges, hydrogen advocates remain optimistic. David Billedeau, president and CEO of the Canadian Hydrogen Association, points to successful projects in B.C. and Alberta. However, the Alberta tests have faced issues with fuelling infrastructure and reliable hydrogen supply at an affordable price. David Layzell, a professor emeritus at the University of Calgary, suggests that the conflict of interest between oil companies and hydrogen could be a barrier. He also notes that the battery technology is rapidly improving, with the Megawatt Charging Standard allowing for faster charging times.
In conclusion, while hydrogen fuel cells have their advantages, the battery-electric revolution is gaining momentum. The economic case for batteries is strengthening, and the technology is rapidly improving. As the race to electrify heavy trucks continues, it seems that hydrogen's reign may be coming to an end, at least for now. The future of heavy-duty transportation may be a hybrid of both technologies, but for now, batteries are pulling ahead in the race to electrify the roads.
