Comparison of CNG Cylinder Sizes: Choosing the Right Fit for Your Needs

Aug. 26, 2023

Compressed Natural Gas (CNG) has emerged as a cleaner and more environmentally friendly alternative to traditional fossil fuels for vehicles and industrial applications. CNG cylinders play a crucial role in storing and transporting this clean energy source. With a variety of CNG cylinder sizes available in the market, it's important to understand the differences between them to make an informed decision that suits your requirements. In this article, we will conduct a comprehensive comparison of various CNG cylinder sizes, exploring their benefits, applications, and considerations.


 Understanding CNG Cylinder Sizes


CNG cylinders are typically classified by their capacity to store compressed natural gas, which is measured in cubic feet (ft³) or liters (L). The size of a CNG cylinder determines its storage capacity and, consequently, its range for vehicles or usage duration for industrial applications.


 Small CNG Cylinder Sizes


 1. Type 1 CNG Cylinder (3,600 psi / 250 bar)


 Capacity: Around 8 to 20 GGE (Gasoline Gallon Equivalent)

 Applications: Small passenger vehicles, motorcycles, residential and light commercial use

 Advantages: Compact size, suitable for vehicles with limited storage space, economical for short commutes


 2. Type 2 CNG Cylinder (3,600 psi / 250 bar)


 Capacity: Around 15 to 25 GGE

 Applications: Compact cars, taxis, light-duty trucks, and buses

 Advantages: Higher capacity than Type 1 cylinders, while still suitable for smaller vehicles, offers a balance between capacity and space requirements


 Medium CNG Cylinder Sizes


 3. Type 3 CNG Cylinder (3,600 psi / 250 bar)


 Capacity: Around 30 to 50 GGE

 Applications: Passenger cars, taxis, light and medium-duty trucks, commercial fleets

 Advantages: Offers a good compromise between capacity and weight, suitable for various vehicle types, commonly used in public transportation


 4. Type 4 CNG Cylinder (3,600 psi / 250 bar)


 Capacity: Around 40 to 60 GGE

 Applications: Buses, medium and heavy-duty trucks, industrial use

 Advantages: High capacity with relatively low weight, excellent for larger vehicles and applications demanding higher fuel storage


 Large CNG Cylinder Sizes


 5. Type 3 CNG Cylinder (3,600 psi / 250 bar)


 Capacity: 60+ GGE

 Applications: Heavy-duty trucks, buses, industrial and commercial use

 Advantages: Maximized capacity for extended range and heavy-duty applications, commonly seen in long-haul transportation


CNG Cylinder Sizes

 Factors to Consider


When choosing a CNG cylinder size, several factors need to be considered to ensure the optimal fit for your specific needs:


 1. Application


The intended application – whether it's for personal vehicles, commercial fleets, or industrial use – will dictate the required CNG cylinder size. Larger vehicles or those with longer travel distances will need cylinders with higher storage capacities.


 2. Space Constraints


The available space for cylinder installation is a crucial factor. Smaller vehicles might have limited space, necessitating the use of compact cylinders, while larger vehicles can accommodate bigger cylinders.


 3. Range Requirements


For vehicles, the desired range between refueling stops is a key consideration. Larger cylinders offer greater range, which is especially important for commercial vehicles covering long distances.


 4. Weight and Payload


The weight of the cylinder itself impacts the vehicle's payload capacity. Choosing a cylinder that strikes a balance between capacity and weight is essential for efficient operation.


 5. Refueling Infrastructure


Ensure that the refueling stations in your area are equipped to handle the specific cylinder size you intend to use. Some stations might have limitations on the pressure or capacity they can accommodate.




CNG cylinder sizes offer a spectrum of options to cater to diverse needs, from personal vehicles to commercial fleets and industrial applications. Selecting the appropriate size involves a thoughtful consideration of your intended use, space availability, and desired range. By understanding the benefits and applications of various CNG cylinder sizes, you can make an informed decision that aligns with your objectives while contributing to a cleaner and more sustainable energy future.
