重型車輛導致的增長 - 年均增長率為14.6％
天然氣，壓縮天然氣（CNG）和液化天然氣（LNG），是增長最快的燃料在運輸部門在美國，美國能源情報署（EIA）報告。代理項目二○一一年至2040年年均增長率為11.9％。CNG專配減壓閥 627調壓器，奧麗斯特減壓閥
重型車輛（HDVs） - 其中包括拖拉機拖車，職業的車輛，公交車，重型皮卡和面包車與車輛總重量評級（GVWR）10001磅或的 - 導致天然氣需求的增長，在整個預測期間。HDVs從2011年的幾乎為零上升到在2040年超過1萬億BTU天然氣燃料消耗，年均增長率為14.6％。
雖然HDVs以天然氣為燃料，具有顯著的增量成本與柴油動力相比，天然氣消費量的增加HDVs促使柴油燃料相比，天然氣價格較低，以及購買天然氣車輛相對高VMT（車輛行駛里程）的應用程序，如拖拉機拖車。
HDVs英里，每年旅游總人數增長了82％，在參考的情況下，從2011年438億英里，在2040年的240億英里，年均增長2.1％。HDVs GVWR與大于26,000磅（主要是拖拉機掛車），占HDVs在2040年卡車VMT和91％的天然氣消費量的大約四分之三。VMT上升的支持，在預測期內的經濟產出上升和道路上的卡車數量增加，從2011年的9.0萬至13.7萬美元，在2040年。
Heavy Duty Vehicles lead the growth - average annual growth rate of 14.6 percent
Natural gas, as compressed natural gas (CNG) and liquefied natural gas (LNG), is the fastest-growing fuel in the transportation sector in the USA, reports the U.S. Energy Information Administration (EIA). The agency projects an average annual growth rate of 11.9 percent from 2011 to 2040.
Heavy Duty vehicles (HDVs) — which include tractor trailers, vocational vehicles, buses, and heavy-duty pickups and vans with a gross vehicle weight rating (GVWR) of 10,001 pounds or more — lead the growth in natural gas demand throughout the projection period. Natural gas fuel consumption by HDVs increases from almost zero in 2011 to more than 1 quadrillion Btu in 2040, at an average annual growth rate of 14.6 percent.
Although HDVs fueled by natural gas have significant incremental costs in comparison with their diesel-powered counterparts, the increase in natural gas consumption for HDVs is spurred by low prices of natural gas compared with diesel fuel, as well as purchases of natural gas vehicles for relatively high-VMT (vehicle miles traveled) applications, such as tractor trailers.
The total number of miles traveled annually by HDVs grows by 82 percent in the Reference case, from 240 billion miles in 2011 to 438 billion miles in 2040, for an average annual increase of 2.1 percent. HDVs, those with a GVWR greater than 26,000 pounds (primarily tractor trailers), account for about three-fourths of truck VMT and 91 percent of natural gas consumption by all HDVs in 2040. The rise in VMT is supported by rising economic output over the projection period and an increase in the number of trucks on the road, from 9.0 million in 2011 to 13.7 million in 2040.
