可再生天然气RNG成为美国重型卡车的发力点

Renewable Natural Gas(RNG)Becomes the Driving Force for Heavy-duty Trucks in the United States

美国重型柴油车面临着减污和降碳的双重压力,以及柴油燃料价格的不确定性。针对这些挑战,美国环保署(EPA)于2022年12月通过了一项重要的规则:《控制新型机动车的空气污染:重型发动机和车辆标准》。这项新规定比现有的标准严格了80%以上。新规要求重型商用车在正常运行时,氧化氮(NOx)的排放量必须限制在0.035 g/马力小时,低负荷时为0.050 g,怠速时为10.0 g。

Renewable natural gas(RNG)is becoming a new choice for heavy-duty commercial vehicles in the United States due to its economic,clean,and stable characteristics.This paper focuses on the concept of renewable natural gas and the preferential policies for the use of renewable natural gas in the United States.
