Despite the fuel cell powertrain, it retains its full payload capacity.

Hyundai has taken the wraps off its hydrogen-powered H350 Fuel Cell Concept van, which musters 136 horsepower (101 kilowatts) and has a range of 262 miles (422 kilometers) on a single tank.

The 46-gallon (175 liter) hydrogen tank is sited under the load bay floor, between the two axles. The fuel cell stack feeds electricity to a 24 kW lithium-polymer battery pack that, in turn, powers the 100 kW electric motor. The result is that 136 hp and 221 pound-feet (300 Newton meters) of torque at the rear wheels. Top speed is claimed to be 93 miles-per-hour (150 kilometers-per-hour).

Despite the room the fuel cell powertrain takes up, there is no loss of load space. Two lengths are available, the shorter with a cargo volume of 370.8 cubic feet (10.5 cubic meters), the longer with a volume of 455.5 cu ft (12.9 cu m). But Hyundai hasn’t said if the weight the van can carry has been reduced by that of the powertrain.

It also comes as a 14-seat passenger van.

The standard, internal combustion-powered H350 was launched two years ago. Hyundai’s first van designed specifically for the European market, it aims squarely at other full-size vans like the Ford Transit and Mercedes Sprinter. Indeed, you can see elements of those rivals in the H350’s styling, though the front end carries a grille familiar from the Korean automaker’s road car range.

Unusually in this sector, the H350 features monocoque construction and is only available with a high-roof body. Like the Fuel Cell Concept, though, two wheelbases are available. Rated at 3500 kilograms (7716 pounds) gross, payload ranges from 1233 kg (2718 lbs) to 1365 kg (3009 lbs). Panel van, passenger van, and chassis cab versions are available.

Power comes from a 2.5-liter turbo diesel engine making 150 hp (112 kW) and 275 lb/ft (373 Nm), or 170 hp (127 kW) and 311 lb/ft (422 Nm). Both send drive through a six-speed manual gearbox to the rear wheels.

Though it is branded as a concept, the H350 FCC could well go on sale. After all, Hyundai was the first manufacturer to put a hydrogen-powered car into production, launching the Tucson/iX35 FCEV in 2013. Considering restrictions on diesel-powered vehicles in city centers are only going to become stricter, demand for emissions-free commercial vehicles will inevitably increase massively in the coming years.
