One Dollar Per Gallon?

Actually, that would have to be LNG, there is no way they could store enough compressed CNG to power a cruise ship. UPS is starting to use a bunch of LNG semis for the increased range when running a standard route from hub to hub, it's easy for them to refill at the hub with their own LNG system. You can store much more natural gas as a liquid than you can compressed at a few thousand PSI - BUT it's hard to make into liquid and must be kept cold.


Correct you are, my mistype.

Looks like those walls might be more of a hazard if a tank blows with those cinder blocks flying.
Poured concrete walls with rebar reinforcement would do the trick.

I believe most city bus fleets have been CNG for years. They have been around here for at least twenty years. Also, garbage trucks and other utility fleets.

Had one in one of my terminals in Iowa today. It is odd seeing a tanker carrying diesel fuel running on cng. They must have some good range. It had Wisconsin liscense plates and the terminal is about 2 hours from Wisconsin.

Diesel engines produce the massive amount of torque
needed for moving 80,000 pounds up a hill.
CNG engines are like gasoline engines when it comes to torque so not a cost effective choice.

The natural gas engines are simply converted diesel engines. A turbocharged natural gas engine is a nice setup. They produce lots of power and torque with super high octane fuel. The one linked in the first post is showing 400hp and 1450ft lbs. Likely not much different than the diesel version of the same engine.

Freightliner? Boooooooo. (I now work for International)

We've been told by an owner of a local paper transport company that the 100+ CNG day cabs that he bought and put into service have not made one dime for the company. The only positive is he can sell to customers who would like or require lower emission based vendors.

Schneider National is in my area (the hideous orange trucks) and they have zero non-diesel tractors. I worked there a few months and saw the numbers and they have over 17k tractors in service. I think that says something, considering that they make purchase decisions based on hundredths of a MPG.

Kwik Trip's HQ and main fleet yard is in Lacrosse, WI. Big facility.

Hmmm. Care to back that with numbers Mr. Engineer?

BTW, speed and grade will determine a horsepower requirement. Acceleration is a torque requirement, but because speed is always involved there is also a horsepower requirement. Torque says nothing about time.

Judging by the Schneider drivers I had come across I bet it is more that they would be sitting at a truck stop trying to figure out how to cram the diesel fuel nozzle into the tank.

I wonder the emissions devices on the LNG engines are less. The emission controls on the new diesels are expensive.
