Hydrogen-powered heavy trucks capable of driving long distances are likely to reach a tipping point toward the end of the decade, according to the heads of the world’s two biggest truck makers.

Martin Daum, chair of industry leader Daimler Truck, told the Financial Times that, while diesel trucks would dominate sales for the next three to four years, hydrogen would take off as fuel between 2027 and 2030 before going “steeply up.”

Martin Lundstedt, chief executive of Volvo Group, which has just bought into a hydrogen joint venture with Daimler, said that, after fuel-cell production started in 2025, there would be a “much steeper ramp-up” toward the end of the decade.
