There are two systems for storing CNG in reservoir tanks, cascade and buffer storage systems. The main objective of the present work is to apply a more detailed fast filling process modeling with the aim of comparison between these.The main operating cost of any CNG refueling station belongs to the compressor input work. Unlike most previous researches, pressure changes of the reservoir tanks during the filling process have been considered which necessary for compressor modeling. The results of the present work have been validated against the experimental data and also compared with the previous studies. The results show that the energy consumption by the compressor for a cycle is found to be 61.86 and 24.50 kWh for cascade and buffer respectively. The average energy consumption to fill a vehicle is found to be 2.38 and 2.72 kWh for cascade and buffer storage systems respectively.
