True. That's why LNG is sold in Diesel Gallon Equivalent (DGE) units.

I have a propane powered truck and all i would need is a different tank to use LNG instead of propane,
True again. Sort of. The tanks are being manufactured by Westport Manufacturing, as are the engine controls.
But to compete with heavy duty applications, the truck would have to act and feel just like a diesel fuel powered truck. It would have to go 700 miles between fill-ups and have all the power I had in my DD-15. To meet that requirement, there is a 15 liter High Pressure Direct Injection (HPDI) based on the Cummins ISX. Shipment of the fully developed LNG trucks will start in 2013.

If you go to Clean Air, you will see where they have partnered with Flying J and Pilot to establish refueling facilities. They built 70 of them in 2012 (on standby, since the trucks are not out yet), and will build another 70 in 2013. T/A truckstops has a different partner, but they are doing the same thing.

I think as soon as the trucks prove themselves to be more profitable than the diesel fuel trucks the industry will make a huge shift. Maybe, 2015 (?) After all, we're talking a 15-20 cent per mile advantage.

And all without Obama's help.
