This document discusses China's growing natural gas vehicle (NGV) market and compressed natural gas (CNG) infrastructure. It provides the following key points: 1. China has over 4 million NGVs and over 4,400 CNG stations as of 2014, with annual growth rates of over 20% for vehicles and stations since 2010. 2. Most NGVs in China are used for public transportation and taxies, fuelled primarily with CNG rather than dual-fuel systems. 3. China is increasing its CNG infrastructure through building daughter refueling stations using hydraulic and 3-in-1 technologies, with capacities from 1,000-2,500 cubic meters per hour.
