South America Gets Its First Hydrogen Truck Fleet
Eight Hyundai XCIENT Class-8 trucks will begin hauling timber across Uruguay starting November 2026, marking the first deployment of hydrogen fuel cell heavy-duty vehicles anywhere in South America. The project, named Kahiros, aims to decarbonize one of the continent's most diesel-dependent logistics corridors.
Uruguay might seem like an unlikely location for a hydrogen freight pilot. But the country already generates over 95 percent of its electricity from renewable sources, primarily wind and hydroelectric. That clean grid makes green hydrogen production viable at costs that would be prohibitive in nations still reliant on fossil-fuel power generation.
The Kahiros Project Infrastructure
A $40 million investment, backed by Santander Group, the International Finance Corporation (IFC), and the United Nations, funds not just the trucks but the entire hydrogen supply chain from scratch. A 4.8 MW solar park will power a dedicated electrolysis plant capable of producing 77 tons of green hydrogen annually.
That tonnage is calibrated specifically for the eight-truck fleet rather than broader commercial distribution. Each truck's 68 kg hydrogen capacity means the electrolysis plant can support roughly 1,130 full refueling cycles per year, or about 141 per truck. For a timber logistics operation running fixed routes between forests and processing facilities, that math works.
Building generation, electrolysis, and dispensing infrastructure simultaneously eliminates the chicken-and-egg problem that has stalled hydrogen adoption in other markets. Trucking companies elsewhere have hesitated to purchase fuel cell vehicles when refueling stations do not exist, while energy companies refuse to build stations without guaranteed demand. Kahiros solves both sides at once.
What the XCIENT Brings to the Job
The XCIENT fuel cell truck is not a concept or a compliance vehicle. Hyundai has been refining this platform since 2020, and the specifications reflect real-world commercial requirements rather than laboratory ambitions.
The powertrain centers on a 180 kW fuel cell stack feeding a 350 kW electric motor that produces 2,237 Nm of torque. Ten onboard tanks hold 68 kg of compressed hydrogen, providing an estimated range of approximately 450 miles per fill. For comparison, a typical diesel Class-8 truck achieves 500 to 600 miles per tank, so the XCIENT approaches diesel parity without reaching it entirely.
Refueling takes roughly 15 to 20 minutes, a critical advantage over battery-electric trucks where charging times for heavy-duty applications can stretch beyond an hour even with the fastest available chargers. In timber logistics, where trucks operate on tight schedules dictated by processing plant capacity, that refueling speed matters enormously. 🌿
Global Track Record Provides Confidence
Uruguay's fleet will not operate in isolation from Hyundai's broader hydrogen program. Sixty-three XCIENT trucks already operate across North America, having accumulated 1.6 million kilometers. In Europe, 165 units have logged over 20 million kilometers in commercial service.
Those European kilometers are particularly relevant. Switzerland deployed the first XCIENT fleet in 2020, and the trucks have operated through Alpine conditions, high-altitude passes, and extreme temperature variations. Timber logistics in Uruguay presents different challenges, including unpaved forest roads and subtropical humidity, but the European data at least confirms the powertrain's durability under sustained heavy use.
Why Timber, Why Uruguay
Timber logistics offers an ideal test case for hydrogen trucks. Routes are predictable, running between plantation forests and processing mills on established corridors. Daily distances are consistent. Fleet operators control enough vehicles to justify dedicated refueling infrastructure. And the industry faces growing pressure from European import regulations that increasingly require proof of low-carbon supply chains.
Uruguayan timber exports, primarily eucalyptus pulp bound for European and Asian paper manufacturers, already carry sustainability certifications. Adding zero-emission transport to the supply chain strengthens that positioning in markets where carbon footprint disclosure is becoming mandatory.
The 77 tons of green hydrogen produced annually at the Kahiros facility would require approximately 860,000 liters of water through electrolysis, a negligible volume relative to Uruguay's abundant freshwater resources in the country's timber-producing interior.
