Answer
Prashant,

It seems that CNG can be supplied by permanent mounted tanks, tanker trucks, or a pipeline.

How natural gas is delivered to transportation customers in California:

In 2004, California produced 15.4 percent of its natural gas from in-state wells. The rest is imported by pipeline from Canada and the Rocky Mountain and Southwestern states. California gas utilities such as Pacific Gas and Electric, Southern California Gas, and San Diego Gas & Electric distribute the fuel to customers. Most CNG vehicle fueling stations are owned and operated by private companies and local governments.

How is natural gas stored?

In smaller fueling locations and on vehicles, CNG is stored in thick-walled steel, aluminum, or composite tanks built to last more than 20 years.
