Toyota (NYSE:TM), Hyundai, and Honda are introducing hydrogen vehicles in the next couple of years, which pits them against electric vehicles in the alternative fuel space. That's where Tesla Motors (NASDAQ:TSLA) has seen a lot of success, and where Ford (NYSE:F) and General Motors (NYSE:GM) are making a big push. Which type of auto will end up the winner? 

Erin Miller sat down with Fool contributor Travis Hoium to discuss this emerging battle. Travis points out in the video below that despite spewing zero emissions from the tailpipe, hydrogen vehicles may actually be dirtier than electric vehicles, especially when you combine a Tesla with a SolarCity (NASDAQ:SCTY.DL) solar installation.
