GM revealed its latest fuel cell demo, the Chevrolet Colorado ZH2, at the Association of the U.S. Army annual meeting and exhibition in Washington, D.C.

The Army will test the off-road midsize pickup in extreme conditions next year. The ZH2 will be the first fuel cell vehicle to wear the GM Hydrotec badge, which has ties to GM's Ecotec gasoline engines, according to the company.

“We see broad potential for fuel cell systems in military, aerospace and other applications while we continue on the path to a commercial vehicle,” said Charlie Freese, executive director, GM Global Fuel Cell Business. 

GM has invested more than $2.5 billion in hydrogen fuel cell technology and is developing a next-generation system that will be the fraction of the size of the the Electrovan, the world’s first hydrogen-powered fuel cell vehicle, according to the automaker.

The Electrovan, which began development in January 1966, was strictly a test vehicle to explore hydrogen as an energy source for vehicle propulsion.
