U.S. Army officials are touting the potential of a new prototype vehicle from General Motors.

The Chevrolet Colorado ZH2 is powered by a hydrogen fuel cell and is whisper-quiet.  Army officials say it may be especially helpful for special forces in need of a stealthy vehicle.   

U.S. Sen. Gary Peters was on hand as GM officials literally handed over the keys to Army researchers. The Michigan Democrat praises the technology in the vehicle.

Battery-powered cars and trucks seem to be winning the day as the way forward to increase fuel efficiency and to cut carbon pollution.

But there was a time when we heard a lot about fuel cells. The cells convert hydrogen into electricity that can then power a car or truck.

That hype died down as people realized there are significant barriers to powering our vehicles with hydrogen.
