Kubota has presented what it describes as the world’s first autonomous hydrogen fuel cell tractor, debuting the concept at the “Hydrogen Energy Park!!” exhibition during Expo 2025 Osaka.
hydrogen power linked to labour and emissions challenges
The Japanese manufacturer said the prototype aims to address two of agriculture’s structural challenges — decarbonisation and labour shortages — by combining zero-emission operation with autonomous and remote-control functionality. The unveiling underscores Japan’s efforts to expand hydrogen’s role beyond transport and industry into agricultural applications.

The tractor uses a solid polymer fuel cell powered by compressed hydrogen to deliver performance equivalent to a 100-horsepower diesel engine. At 4.38 metres long and 2.2 metres wide, it is designed for large-scale farming operations. Kubota said hydrogen’s higher energy density compared with batteries allows for extended operation and faster refuelling, making it more suitable for heavy-duty use than current battery-electric models.
Kubota to begin hydrogen tractor field trials in japan
Field trials are planned in Japan to test autonomous driving, hydrogen refuelling logistics and long-term reliability under agricultural conditions. “The development reflects Kubota’s commitment to sustainable and intelligent agricultural machinery,” the company said in a statement. It has not provided a commercialisation timeline.
Kubota explores hydrogen internal combustion engines alongside fuel cells
The firm is also exploring hydrogen internal combustion engines, having developed a 3.8-litre prototype for off-road equipment. It said both technologies could have a role depending on operating requirements.
Implications for hydrogen agriculture and japan’s clean energy policy
Japan’s government has been promoting hydrogen infrastructure as part of its clean energy transition, offering a favourable environment for such trials. However, fuel availability and cost remain constraints to wider deployment in agriculture, where diesel remains dominant and margins are thin.
For equipment manufacturers, the move reflects growing interest in how hydrogen could complement electrification in heavy machinery. For policymakers, it highlights the broader test of whether hydrogen can be made cost-competitive outside industrial and transport hubs — a question that may determine whether Kubota’s concept remains an exhibition prototype or a glimpse of farming’s low-carbon future.
