The hydrogen-powered off-roader will eventually be tested by the US Army to explore the viability of hydrogen powertrains for military applications.

General Motors has revealed the Chevrolet Colorado ZH2. a hydrogen-powered concept designed for US Army trials.

The midsize pickup chassis has been reinforced and stretched to span more than seven feet wide, standing more than 6.5 feet tall on 37-inch off-road tires and modified suspension.

The company suggests hydrogen fuel-cell technology could have several potential benefits for military use. It is near-silent, with reduced thermal signatures for stealthy operation. An electric drive system also provides high wheel torque at all speeds, with low fuel consumption and water as a usable by product.

The ZH2 can operate as an electrical generator, thanks to an Exportable Power Take-Off (EPTO) unit, potentially eliminating the need for separate batteries or generators in areas where electric power is unavailable.

GM collaborated with the US Army Tank Automotive Research, Development and Engineering Center (TARDEC) to develop the ZH2 from contract to concept in less than a year. A bit more work needs to be done before the military begins tests next year.
