由于人们对能源依赖、空气质量和排放以及最近的气候变化的担忧日益增加，天然气汽车正在开发。天然气汽车的主要优点是燃料成本较低。一些经济和技术因素，如有限的范围和相关基础设施的可用性，阻碍了天然气汽车的广泛采用。提出了一个压缩天然气（CNG）汽车与汽油动力汽车竞争可能性的财务分析模型。该模型评估了通勤者在多大程度上发现采用CNG汽车在美国经济上是可行的。结果表明，通勤者谁会采用CNG汽车的百分比是小的，即使加油基础设施得到充分发展和CNG汽车广泛可供购买。更多的车辆行驶里程和汽油价格上涨鼓励通勤者采用CNG汽车，而更高的燃油经济性和购买价格差异导致采用率较低。在某些情况下，根据模型参数的值而变化，通勤者购买CNG车辆作为他们的第二辆车，并保留汽油动力汽车作为他们的第一辆车。
Natural gas vehicles are being developed because of increasing concerns about energy dependence, air quality and emissions, and, more recently, climate change. The major advantage of natural gas vehicles is their lower fuel cost. Several economic and technical factors such as limited range and availability of relevant infrastructure prevent widespread adoption of natural gas vehicles. A model for the financial analysis of the possibility of compressed natural gas (CNG) vehicles being competitive with gasoline-powered vehicles is offered. The model evaluates the extent to which commuters find adoption of CNG vehicles to be economically viable in the United States. The results indicate that the percentage of commuters who would adopt CNG vehicles is small, even if fueling infrastructure were fully developed and CNG vehicles were widely available for purchase. A larger number of vehicle miles traveled and increased gasoline prices encourage commuters to adopt CNG vehicles, while higher fuel economy and purchase price differentials result in lower adoption rates. In some cases, which vary in accordance with the values of the model’s parameters, commuters purchase a CNG vehicle as their second car and keep a gasoline-powered car as their first.
