In this paper, general characteristics related to the supply chain of compressed natural gas (eng. CNG - Compressed Natural Gas) are given. Compressed natural gas is stored in a compressed gas state in tanks (bottles), in contrast to liquefied natural gas (eng. LNG - Liquefied Natural Gas) in which natural gas is stored in liquid form. The production and storage of compressed natural gas is somewhat cheaper compared to liquid natural gas, with the fact that the storage volumes are different. From all of this, there is a need to analyze the supply chain with CNG from the aspect of the compression process, transportation and storage costs. This paper describes the process of exploitation of CNG as a fuel for the conditions of functioning of the supply chain in Bosnia and Herzegovina. Real data related to the process of compression, transportation and storage of natural gas were taken from the company: "Prvo gasno društvo, D.O.O. Zvornik". The paper analyzed the indicators of chain like as: energy efficiency, CO2 emissions and production cost reduced per 1 kwh of energy expressed in the lower heat value (LHV) of the distributed fuel. Also, a short comparison the supply chains by CNG, wood pellets and chips as fuels are presented by MCDM method. From the aspect of transport logistics, CNG has significantly better predispositions compared to other supply chains of pellets and wood chips, taking into account the energy efficiency of its process as well as the cost of supply logistics itself. However, CNG belongs to the category of fossil fuels.
