The process of storing high-pressure compressor gas is done in storage tanks and is sent to distributors when needed. The storage tank system is installed in 3 banks to minimize the fueling time.

A standard Type 3 tank is 20–26 inches in diameter. Advanced Structural Technologies manufactures CNG tanks of up to 26 inches in diameter. They are high pressure and high capacity, making them suitable for both storage and transport solutions for CNG.
What is the capacity of the CNG cylinder, and mileage from one fill ? The tank which has a storage capacity of 60 water liters can store up to 8 to 10 kilograms of CNG. A mid-sized car of about 1200cc can run up to 175 kms to 200 kms in one filling.

The most common way to store natural gas is in large caverns underground. It can also be stored in smaller quantities in tanks above ground.
CNG cylinders are designed and built in such a way so as to withstand high pressure. The maximum pressure in a CNG cylinder is up to 200 kg/cm2 (g) (about 2840 psi (g). CNG cylinders are specially designed and manufactured.
