CNG Stations in China: A Comprehensive Guide

Compressed Natural Gas (CNG) has emerged as a vital alternative fuel source in China, driven by the country’s commitment to reducing emissions and promoting sustainable energy. With over 9,000 CNG refueling stations currently operational, the infrastructure supporting CNG vehicles is rapidly expanding. This guide will delve into the technical features, types of CNG dispensers, and the overall landscape of CNG stations in China.

Overview of CNG Stations in China

CNG stations are crucial for the refueling of natural gas vehicles (NGVs). The Chinese government has actively promoted the use of CNG vehicles since 2006, leading to significant advancements in both vehicle technology and refueling infrastructure. Major state-owned companies like CNPC, Sinopec, and CNOOC dominate the market, holding a combined market share of approximately 52%.

The convenience of CNG, coupled with its lower cost compared to traditional fuels, has made it an attractive option for consumers. As of January 2025, the number of CNG refueling stations is expected to grow significantly, with projections indicating a rise to around 20,000 stations.
