Most nat gas fleet's that are operatng efficently do so today because they have lighter loads and shorter runs. Maintence costs run 800-1000 annual per truck higher than diesel. Shop upgrade is expensive and contingent to the jurisdiction of your local regs. and fire marshal. Low pressure fueling time averages about 45 minutes. High speed fueling options are expensive and complex, an there are few public options outside of private fueling centers.

Great topic !  Natural Gas is a fantastic opportunity to lower our reliance on Foreign Fuel and create jobs in North America, who wouldn't want to stop sending the over $1 Trillion dollars to foreign fuel providers ?  To be sure, the first issues of the day are engine availability and fuel locations.  Cummins Engines is tackling the issue of engines (the 12L engine with up to 400hp will be available for full production as of August of 2013 and the 15L in late 2014/early 2015) and Clean Energy Fuel Co. is tackling the issue of fuel locations (by creating America's Natural Gas Highway in a "build it and they will come" mentality). A lot of other companies are gettting on the bandwagon (additional tank manufacturers and conversion companies) and this will continue as the growth of Natural Gas engines continues in the transportation industry - all for the good of North America!  Job growth, less foreign fuel reliance, financial security.....The concept of "buying American" as a fuel source is returning as THE TOPIC OF CONVERSATION in transportation today!

I think a big concern will be maintenance and the availability of quick repairs, there is already a huge shortage of diesel mechanics nationwide as more of them are baby boomers and are retiring. I have heard that some turn around times at some dealers are two weeks now!

They have to much hope for Natual Gas. It's was tried before in the mid 90s . It works ok with only local deliveries and city busses. In a OTR truck you will have to fuel up more than once a day and the BTUs are alot lower than diesel is. It wasn't economical then and won't be now, with out alot of incentives.. They were promised them last time and the government reneged on their end of it and the LNG died on the spot. Ask Jack B Kelly.. That was the beginning of the end for that company. They had fueling stations that were going to be put in where ever needed, or Cummins.. They had a LNG engine that was being used.. But it just feels so warm and fuzzy..

We are running over 80 LNG trucks.

 

From the above questions, all questions are a concerned, no different then any existing trucks.

 

The way the questions are asked are misleading. There is a big difference between CNG, LNG, Warm-LNG fuel, etc...

 

Very few people understand natural gaz, some beleive you can repower an existing engine and so. All this is wrong and this is one of the reason the shift to LNG engine is so slow. Yes the technology has to evolved, people too. There is much bigger issues not said and unknown from the public in general, that must be adressed and will contribute in the futur to the development of LNG engine in the future.

 

LNG is a way toward the future, but this is not for everybody, now.

My most pressing concern of the natural gas issue is availability of conversion components for us in the mechanic field to take off the EFI system from the gas burners and install the LNG EFI  components.  Just a little hard now to check on interchangeability of LP parts with LNG systems.  Never got enthused with LP gas with cost of $4.50 plus/gallon and less power and less MPG to boot. LNG looks more promising for use in my service trucks, am eagerly waiting and looking for pieces/parts.  Love to see a conversion kit for my 12V 92.

Jeff, This is much different than the 90's! You're spot on about the Btu delta, but the economics are there for the right type of operation!
