Natural gas is domestically produced and readily available to end-users through the utility infrastructure. It is also clean burning and produces significantly fewer harmful emissions than reformulated gasoline or diesel when used in natural gas vehicles. In addition, commercially available medium- and heavy-duty natural gas engines have demonstrated over 90% reductions of carbon monoxide (CO) and particulate matter and more than 50% reduction in nitrogen oxides (NOx) relative to commercial diesel engines. Natural gas can either be stored on-board a vehicle as compressed natural gas (CNG) at 3,000 or 3,600 psi, or as liquefied natural gas (LNG), typically at 20-150 psi. LNG is cooled to -260° F at ambient temperatures. Natural gas can also be blended with hydrogen.
