Possibilities of mobile auto-gas tankers usage in the development of the natural gas stations chain

The article deals with possibilities of the development of the petrol station chain, based on the compressed natural gas (CNG), where mobile auto-gas tankers are used, on the example of the Republic of Tatarstan. The calculation example of the quantity of stations, based on the CNG, is given in the article.
Results
The petrol station chain, based on the CNG, that includes NGV Gas station and mobile auto-gas tanker, with the sufficient free traffic for automobiles on CNG was developed on the example of the Republic of Tatarstan. The aim of the chain is to develop the self-sustaining gas-engine market.
Сonclusions
It is necessary to construct 23 new NGV Gas stations and to put into service 94 mobile auto-gas tankers to provide the distance between gas stations in 50 km, taking into account the existence of 18 NGV Gas stations in Republic of Tatarstan at the moment. Initially, it would be preferable to install the mobile auto-gas tanker instead of 22 NGV Gas stations, during the gasification of means of transport; it can give an opportunity to reduce expenses for constructing the petrol station chain.
