It is possible, and may someday be practical, to handle extreme pressures (THOUSANDS of pounds per square inch) in quick-fueling sites, but until then, it may be more sensible to have swap-out tanks, much like the propane tanks on your barbeque grill.

CNG vehicle fueling is not a complicated technology. It has been done for decades and the equipment has long since been standardized.

The real problem is a chicken / egg issue. Not many want to buy a CNG vehicle without convenient places to refuel. Not many want to invest in a CNG refueling system without a sufficient customer base to repay the initial cost and make a profit.

A few companies are spending money on this, but it is still very limited locations to refill.

How is it going to work in all these small cars that the government has been pushing with its CAFE standards?
