Compressed Natural Gas Vehicle Fuel Survey

In response to the corresponding drop in natural gas prices, several automakers have introduced new models of natural gas vehicles (NGVs) for medium-duty and heavy-duty use and are working to expand the markets for NGVs in the United States. A key challenge to automakers in their plans for market expansion is the lack of data on compressed natural gas (CNG) quality at existing refueling stations and in regions where new CNG stations would be built. Data on water vapor in CNG is of particular interest because of its potential to corrode NGV fuel systems and to form hydrates that can plug fuel valves. The quality of natural gas delivered by transmission pipelines and local distribution companies to CNG stations varies, depending on factors such as available gas supplies, the amount of processing performed on the gas, and supplies drawn from storage during high-demand months. The recent increase in “shale gas” production in the United States has increased these variations since the last published study of pipeline gas compositions. To help automakers and other stakeholders understand the geographic variations in natural gas quality that NGVs may encounter, Southwest Research Institute (SwRI) has obtained data on pipeline natural gas quality and CNG quality at CNG stations across the United States. The goals of this project were to provide the Coordinating Research Council with data on natural gas quality at transmission pipelines, local distribution company pipelines, and CNG dispensers, and to provide CRC with an understanding of any geographic variations in natural gas components and parameters affecting NGV performance.
