What: Shares of natural gas fuels specialist Clean Energy Fuels
So what: Westport Innovations
Now what: It's exciting to see cleaner and more sustainable fuel technologies slowly making their way into the mainstream. Yeah, LNG is still a petrochemical product just like the oil, diesel, and gasoline we all know and loathe, but a less-exploited and somewhat more eco-friendly one. If Shell and friends can make this work for commercial vehicles at first, we'll have a low-cost alternative to gas-and-battery hybrids for the consumer market soon enough. When the natural gas runs out, let's just hope we'll have cold fusion reactors in every home already.Fool contributor Anders Bylund holds no position in any of the companies discussed here.
