Navistar is introducing a hydrogen fuel-cell semi truck for customer implementation through a new zero-emission long-haul system in collaboration with General Motors and OneH2.

Navistar plans to make its first production model International RH Series fuel cell electric vehicle (FCEV) commercially available in model year 2024, according to Navistar. Test vehicles are expected to begin the pilot phase under the new, complete solution at the end of 2022. The integrated solution will offer a target range of more than 500 miles and a hydrogen fueling time of less than 15 minutes.

General Motors will supply its Hydrotec fuel cell power cubes to Navistar for use in the International RH Series, the automaker siad. Navistar's FCEV will get energy from two GM Hydrotec fuel cell power cubes.

The system will be initially piloted by J.B. Hunt Transport, Inc., a subsidiary of J.B. Hunt Transport Services, Inc. 

"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. "We are excited to provide customers with added flexibility through a new hydrogen truck ecosystem that combines our vehicles with the hydrogen fuel cell technology of General Motors and the modular, mobile and scalable hydrogen production and fueling capabilities of OneH2."

Each Hydrotec power cube contains 300-plus hydrogen fuel cells along with thermal and power management systems. They are compact and easy to package into many different applications.

The combined propulsion system within the International RH 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, according to the companies.

"GM's vision of a world with zero emissions isn't limited to passenger vehicles. We believe in EVs for everyone," said Doug Parks, GM executive vice president of Global Product Development, Purchasing and Supply Chain. "We're thrilled to work with like-minded companies like Navistar and OneH2 to offer a complete solution for progressive carriers that want to eliminate tailpipe emissions with a power solution that can compete with diesel."

Under its partnership agreement with Navistar, OneH2 will supply its hydrogen fueling solution, which includes hydrogen production, storage, delivery and safety. In addition, Navistar is taking a minority stake in OneH2. 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.

These newly announced collaborations with General Motors and OneH2 represent new milestones in Navistar's phased development of hydrogen fuel cell solutions. These technologies leverage Navistar's battery electric vehicle platforms and provide the customer with a single-source, fully integrated zero-emission solution that includes vehicles, fueling and service, according to the company.
