The following video is part of our "Motley Fool Conversations" series, in which industrials editors/analysts Isaac Pino and Brendan Byrnes discuss topics around the investing world.

In today's edition, Isaac and Brendan discuss three catalysts that could propel Clean Energy Fuels in the near future. Forget the fact that the Natural Gas Act hit a roadblock in March; the economics of natural gas make sense for long-haul trucking. The price discrepancy between natural gas and diesel remains intact, significant natural gas exports are a few years off, and production costs are rising rapidly for petroleum resources. Further, the price for upgrading a tractor-trailer to a natural gas engine continues to decline. 

While behind-the-fence operators find natural gas especially enticing -- think regional fleets like UPS and Waste Management -- a company like Clean Energy Fuels could lay the groundwork for cross-country transportation. Find out why Clean Energy could be a strong buy by watching the following video.

The natural gas market could offer enormous profits for an infrastructure play like Clean Energy, but the payoff might be years down the road.
