In the following video, Fool consumer-goods/industrials analyst Blake Bos discusses how the current natural gas boom has spurred interest in hydrogen-fueled cars. 

The expansion of natural gas infrastructure resulting from increased gas production would make it easier in the future to support hydrogen-powered vehicles, Blake says.

There are environmental concerns regarding the production of hydrogen from natural gas.  However, Blake shares research that points out a potential long-term issue with the current battery technology that Tesla Motors (TSLA 4.96%) and other manufacturers use. Blake also identifies international companies that are embracing hydrogen technology, including Honda (HMC -2.21%) and Toyota (TM -3.23%).
