Oh gosh, I can remember using CNG on road vehicles more than 25 years ago.  It was a large E-250 van with a conversion kit that basically put new jets in the carb, and bolted on a different fuel tank system.  The fuel tank was a very large thing on the side of the vehicle and filling it required gloves to prevent frostbite.

We called it "The Rolling Bomb" because we were never too sanguine about having a large tank of natural gas under pressure under the side of the vehicle. One crash could make for a spectacular explosion.  Mind you, we were young and ignorant in those days, but still knowlegable enough to know what a large tank of propane can do.  The van performed reasonably well, but I was always very nervous driving it. 

I would hope that these vehicles are carefully tested for crash-worthiness and that the propane tanks are able to hold sufficient fuel to actually get somewhere.

Next: Let's see someone build a fuel cell with CNG and use it to power the vehicle electrically. I'll bet that will give the Otto cycle folk a run for their money...

Safety concerns

How is the auto industry addressing the obvious safety concerns of compressed natural gas in moving vehicles?  Until a strong solution presents itself, I see this as a very limiting factor.

Natural gas vehicle introduction will erradicate the problem of exhaustion of natural resources. Toaday vehicle used much fuel then used in home. So such intrduction of natural gas is a big boon for today's world.

Chuck, Very interesting post. In the U.S., I would think that the availability of fuel will be a major deterrent other than fleets that arrange access to meet their needs.

Here are a few more numbers from Navigant Research's study. In 2013, U.S. sales of natural gas vehicles is expected to be 26,700. Italy will be 161,000, Ukraine 112,000, Pakistan 254,000, China 421,000, Iran 450,000. The compound annual growth ratefor natural gas vehicles is expected to be 16% through 2020.

The numbers will definitely increase, but the pecentages will still be small. Even if we reach 35 million vehicles on the road worldwide by 2020, it will still only amount to about 2.3% of the overall. And most of those will be outside the U.S. (The number of vehicles on the road by that time will be 1.5 billion.)

Where's the natural gas car boom?

Nice slide show, chuck. Given the downward spiral of natural gas prices and the surprising volume of gas now extracted in North America, there should be a natural gas vehicle boom in the U.S.
