"Why go to liquid when vehicles can burn compressed natural gas?" Because in some places - like the North Slope - conversion to liquids enables transportation. Bob

>> Why go to liquid when vehicles can burn compressed natural gas? << Because CNG takes up too much space, fewer BTU's per unit volume. So you get greater range per fill up with liquids without giving up a lot of trunk space for pressure bottles.

In the mid 80 GM had a fleet of CNG vehicles here in Houston. They were leased by our local utility. Althought the infrastructure was sparse there were fuel card secure places around out exterior loop that allowed sufficient access. The worst feature of CNG is it requires a very high pressure tank. In the mid 80's one of these tanks which was comprised of a fiberglass exterior with metal hydroformed end caps. While refueling, one of these end caps blewout through the Pick ups rear quarter panel and injured the driver while refueling. GM purchased back the vehicles and dropped the project, as there was no way of having a cruising range with out high pressure tanks. It is an inherent danger and GM was not in the mood for huge liability problems. The utility did NOT want to give back the trucks. GM insisted. I know the man who handed over the repurchase check. That's the down side of CNG - fuel storage liability. Bob
