Kubota Corp. showcased what it claims is the world’s first hydrogen-powered self-driving tractor at the World Expo in Osaka on Monday, combining clean energy with automation as agricultural machinery makers race to meet emissions targets.
The 100-horsepower machine, measuring 4.4 meters long and 2.2 meters wide, lacks a driver’s seat and can operate autonomously or via remote control for half a day on a single charge, according to Jiji Press. The concept model will be displayed through Thursday at the expo.
While the Osaka-based manufacturer calls the machine a breakthrough, significant hurdles remain before hydrogen tractors reach farmers’ fields. The company previously indicated hydrogen-powered models would cost roughly 40% more than diesel alternatives, and commercial rollout timelines have slipped since initial 2025 targets.
The agricultural machinery sector faces mounting pressure to decarbonize operations. Market researchers project the hydrogen-powered tractor market could reach $4.54 billion by 2035, though current adoption remains limited by infrastructure constraints and high costs.
The machine generates electricity from hydrogen and oxygen reactions, producing only water vapor, addressing environmental concerns that have prompted government incentives for clean agricultural technology. However, the lack of widespread hydrogen refueling infrastructure and production costs continue to challenge commercial viability.
Competitors including John Deere and CNH Industrial are also developing hydrogen-powered farm equipment, intensifying competition in the nascent market segment.
