General Motors will supply its Hydrotec fuel cell power cubes to Navistar Inc. for use in its production model fuel cell electric vehicle (FCEV) – the International® RH^TM Series.

Navistar's FCEV will get energy from two GM Hydrotec fuel cell power cubes. Each Hydrotec power cube contains 300-plus hydrogen fuel cells along with thermal and power management systems. The power cubes are compact and easy to package and can be used in a wide range of applications, including marine, earth-moving and mining equipment, locomotives and power generators.

The long-haul system which will be initially piloted by J.B. Hunt Transport, Navistar said in a statement.

The combined propulsion system within the International^® RH^TM Series FCEV will feature better power density for short-range travel, better short-burst kW output and a per-mile cost expected to be comparable to diesel in certain market segments.

Hydrogen fuel cells offer great promise for heavy duty trucks in applications requiring a higher density of energy, fast refueling and additional range," said Persio Lisboa, Navistar president and CEO. "J.B. Hunt has committed to utilize the solution on dedicated routes and to share key learnings."

Navistar plans to make its first production model International^® RH^™ Series fuel cell electric vehicle (FCEV) commercially available in model year 2024. Test vehicles are expected to begin the pilot phase under the new, complete solution at the end of 2022. The integrated solution will be competitive with other powertrain offerings with a target range of 500+ mi and a hydrogen fueling time of less than 15 minutes.

Under its partnership agreement with Navistar, OneH2 will supply its hydrogen fueling solution, which includes hydrogen production, storage, delivery and safety. Through its affiliates, OneH2 plans to kickstart substantial hydrogen heavy truck refueling infrastructure by incorporating more than 2,000 International^® RH^™ Series FCEVs into existing truck fleets in the near term.
