The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...

Natural Gas Buses: Separating Myth from Fact

Increasing numbers of transit agencies across North America are making the choice to convert their bus fleets to compressed natural gas (CNG), and even more are seriously considering it. Natural gas buses now account for at least 20% of all new bus orders. However, it becomes difficult for fleet operators to fairly evaluate the potential benefits of an alternative fuel program if they are confr...

Impact of Compressed Natural Gas Fueled Buses on Street Pavements

Federal Clean Air Act Amendments of 1990 (CAAA) and the Energy Policy Act of 1992 (EPACT), together with other state regulations have encouraged or mandated transit systems to use alternative fuels to power bus fleets. Among such fuels, compressed natural gas (CNG) is attractive, although it must be stored in robust, heavy pressurized cylinders, capable of withstanding pressures up to 5,000 psi...
