The rapid expansion of China’s natural gas pipeline network is stimulating the construction of CNG plants (also called CNG Mother Station in China) alongside the pipeline routes.

By 2021.12, the statistics shows there are 724+ CNG plants (existing, constructing and planning) in China, among which 542+ plants were put into operation. 95% of the CNG plants compress and sell conventional natural gas. Over half of the rest 5% CNG plants use coal bed methane as their gas source.

The downstream market also provides a solid basis for CNG suppliers: among China's total 4,667+ franchised city gas zones, over 335 zones use CNG as their exclusive city gas source while 2075+ other zones use CNG as supplementary city gas source and feul for natural gas vehicle.
