Really good comment that touches upon just some of the factors that go into "real world" stuff.
Now, get this ...
In a few weeks, outfit called Clean Energy is set to unveil a potentially game changing paradigm.
Clean Energy was just partially bought out by Total (big bucks, global footprint, deep analytical resources).
With Total's financial backing - and in an effort to jump start this CNG adoption for vehicles nationwide, Clean Energy will offer a VERY attractive leasing program for CNG trucks using Cummings/Westport ISX12N natgas engine.
If it proves successful, Clean Energy will create numerous new customers for their CNG fueling stations.
It would appear to be only a matter of time for the transition from liquids (gasoline/diesel) to gaseous takes place.
With the adoption of IMO 2020 next year, competition for low sulphur diesel is set to soar ... further enhancing the allure of natgas.
