The race to electrify heavy trucks is heating up, and the question on everyone's mind is: Hydrogen vs. batteries, which is winning? The answer, it seems, is more complex than a simple yes or no. While hydrogen fuel cells have long been touted as the solution to decarbonizing heavy vehicles, recent developments suggest that battery-electric trucks are pulling ahead in the race.
The Hydrogen Advantage
Hydrogen fuel cells have been seen as a promising technology for heavy trucks due to their high energy density and fast refueling times, which are comparable to diesel. Canada's Hydrogen Strategy, released in 2020, projected that hydrogen demand in transportation could reach 13% of Canada's total by 2050, with fuel cells playing a significant role in trucking. The strategy highlighted the weight of batteries as a challenge for heavy-duty trucks, suggesting that hydrogen fuel cells could overcome this issue.
China's Shift Towards Batteries
However, China's recent energy strategy for heavy-duty trucks tells a different story. The country has been a pioneer in testing and adopting both hydrogen and battery-electric truck technologies. In 2025, China accounted for 95% of the world's fuel cell trucks and 90% of electric truck sales. The Chinese battery giant CATL plans to establish 900 commercial heavy-truck swapping stations by the end of 2026, showcasing the rapid development of charging infrastructure for batteries.
The economic case for battery-electric trucks is also becoming more compelling. While battery trucks are currently more expensive upfront, their fuel costs are lower, and the technology is improving rapidly. The Megawatt Charging Standard, published by the global EV industry, will enable heavy trucks to charge from 20 to 80% in under 30 minutes, addressing the issue of long charging times.
The Hydrogen Challenge
Hydrogen fuel cells face challenges in the heavy-truck market. The cost of hydrogen fuel and the infrastructure required to produce and distribute it are significant barriers. In contrast, battery technology has won the race to electrify light-duty vehicles, and for heavy trucks, it's looking like the door is closing for hydrogen too.
The Canadian Perspective
In Canada, the push to electrify commercial vehicles is hindered by the battery's limitations. Lithium-ion batteries need to become stronger, cheaper, and lighter to support long-haul trucking. The Canadian Hydrogen Association's David Billedeau argues that hydrogen has established technologies and proven pilots, but the industry faces challenges with fueling infrastructure and reliable hydrogen supply.
The Future of Hydrogen Trucks
Despite the challenges, hydrogen trucks are not entirely written off. Sinopec, a Chinese state-owned oil and gas company, believes that hydrogen fuel cells must differentiate themselves from batteries and amplify their advantages for heavy loads and long distances. However, the industry's focus on batteries and the rapid improvements in battery technology suggest that hydrogen trucks may need to find their unique selling point to stay in the race.
In conclusion, the race to electrify heavy trucks is far from over, and both hydrogen and battery-electric technologies have their strengths and challenges. As the industry continues to evolve, finding the right balance between these technologies will be crucial in achieving a sustainable and efficient transportation future.
