General Motors will supply its Hydrotec fuel cell power cubes to freight truck maker Navistar for use in its production model fuel cell electric vehicle (FCEV) – the International RHTM Series. The Navistar tie-up is the latest for GM with its 'hydrotech' fuel-cell technology.

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.

Navistar is targeting the fuel-cell-powered semitruck to offer more than 500 miles of range and a hydrogen fueling time of less than 15 minutes.

A pilot for the hydrogen powered semitrucks is planned for the end of 2022, with the first trucks available in 2024. 

The deal with Navistar follows a hydrogen tech deal announced for GM with electric freight truck developer Nikola. Its higher energy density means that Hydrogen is seen as a better bet for electric drive HGVs than the lithium-ion batteries used for light duty vehicles.
