Compressed Natural Gas Vehicles and Fueling Stations


Take your compressed natural gas vehicles and fueling stations to global markets with confidence

Did You Know?

  • Favorable government initiatives, such as subsidies in key consuming economies of Asia Pacific such as China, and India, are projected to fuel the demand for CNG through 2025.
  • The cost of fueling with CNG is substantially cheaper than petroleum-based fuels, giving fleet operators a potential opportunity to capitalize on a major cost-saving.

The commercial transportation industry represents a significant portion of worldwide energy demand and contributes large amounts of global greenhouse gas emissions. Many providers are looking for ways to contribute to decarbonization, such as using compressed natural gas (CNG) vehicles.

CNG is formed when natural gas is compressed to less than one percent of the space it would occupy in the atmosphere. This makes CNG an appealing option because it is cheaper, cleaner, and abundantly available.

CSA Group offers testing and certification services to help you meet compliance requirements for CNG vehicle and fueling stations. We also offer a full suite of standards, training, and personnel certification programs to support the CNG industry. Access to a database is available to help find qualified CNG cylinder and fuel system inspectors in your area.
