Mehrabi told Shana that for the time being, the CNG capacity can be doubled but to guarantee life span and safety of the CNG stations, the capacity will be increased up to 50 percent, let's say up to 30 million cubic meters.

He went on to say that the only source of his Company's concern is safety that is fully observed in the manufacturing phase but periodic supervision and safety should be taken more into consideration.

He said each compressor can operate up to two times its current capacity.
