Hyundai hydrogen fuel-cell HD truck packs as much battery capacity as GMC Hummer EV

Hyundai on Tuesday announced upgrades for its Xcient Fuel Cell heavy-duty truck, indicating the automaker remains committed to fuel-cell commercial vehicles.

Hyundai claims the Xcient Fuel Cell is the world’s first mass produced hydrogen fuel-cell heavy duty truck, but the automaker only plans to delivery 1,600 to European fleet customers by 2025. Production of the upgraded version also doesn’t start until August.

Offered in 6×2 and 4×2 configurations, the Xcient Fuel Cell uses a pair of 90-kilowatt fuel-cell stacks, which power an electric motor rated at 350 kw (469 horsepower) and 1,649 pound-feet of torque.

Seven hydrogen tanks can store a combined 31 kilograms of fuel according to Hyundai. The company said refueling takes between eight and 20 minutes (depending on ambient temperature), with a lower pressure of 35 megapascals, which makes hydrogen easier to store and dispense. Range is estimated at around 248 miles.

However, the Xcient Fuel Cell also uses three 72-kilowatt-hour battery packs for supplementary power. That’s about as much battery capacity as the upcoming GMC Hummer EV pickup truck.
