Nissan's Leaf represents a big bet on battery-electric technology. But the company has also made a bet on hydrogen cars, and now its CEO is saying that he's skeptical of hydrogen's chances. Photo credit: Nissan.

Tesla Motors (NASDAQ:TSLA) CEO Elon Musk has made his feelings on hydrogen fuel-cell cars clear: He thinks the technology is a dead end. Of course, you'd expect him to say that: With Tesla, he's made a huge bet on hydrogen's biggest rival, battery-electric cars. It's only natural that he'd talk down the competition. 

But this week, Nissan (NASDAQOTH:NSANY) CEO Carlos Ghosn expressed his own skepticism about hydrogen-car technology -- and while Nissan has made its own big bet on battery-electric cars, it has also joined with Ford (NYSE:F) and Daimler (NASDAQOTH:DDAIF) in a project to bring fuel-cell vehicles to market later this decade. 

What's the deal? In this video, Fool contributor John Rosevear explains where Ghosn's skepticism is coming from -- and why some of his arguments against hydrogen cars are worth considering carefully.
