The latest GM's hydrogen fuel cell concept - Chevrolet Colorado ZH2 (see unveiling) - made its first public appearance at  SEMA (aka the Specialty Equipment Market Association) in Las Vegas last week.

Moving forward, the US Army and GM are looking at FCV technology, and the logistics of hydrogen in the field, so it will be interesting to see how the collaboration and ultimate conclusions on the tech pan out.

On the positive side, the effects of using FCVs are clean water instead of emissions, and the capability to export electricity in the field.

Below:  Lots of gallery pictures from the show, plus some bonus live footage
